How many types of ball mill 1. Based on the axial orientation a. Horizontal ball mill. It is the most common type supplied from ball mill manufacturers in China. Although the capacity, specification, and structure may vary from every supplier, they are basically shaped like a cylinder with a drum inside its chamber. As the name implies, it comes in a longer and thinner shape form that vertical ball mills. Most horizontal ball mills have timers that shut down automatically when the material is fully processed. b. Vertical ball mills are not very commonly used in industries owing to its capacity limitation and specific structure. Vertical roller mill comes in the form of an erect cylinder rather than a horizontal type like a detachable drum, that is the vertical grinding mill only produced base on custom requirements by vertical ball mill manufacturers. 2. Base on the loading capacity Ball mill manufacturers in China design different ball mill sizes to meet the customers from various sectors of the public administration, such as colleges and universities, metallurgical institutes, and mines. a. Industrial ball mills. They are applied in the manufacturing factories, where they need them to grind a huge amount of material into specific particles, and alway interlink with other equipment like feeder, vibrating screen. Such as ball mill for mining, ceramic industry, cement grinding. b. Planetary Ball Mills, small ball mill. They are intended for usage in the testing laboratory, usually come in the form of vertical structure, has a small chamber and small loading capacity. Ball mill for sale In all the ore mining beneficiation and concentrating processes, including gravity separation, chemical, froth flotation, the working principle is to prepare fine size ores by crushing and grinding often with rock crushers, rod mill, and ball mils for the subsequent treatment. Over a period of many years development, the fine grinding fineness have been reduced many times, and the ball mill machine has become the widest used grinding machine in various applications due to solid structure, and low operation cost. The ball miller machine is a tumbling mill that uses steel milling balls as the grinding media, applied in either primary grinding or secondary grinding applications. The feed can be dry or wet, as for dry materials process, the shell dustproof to minimize the dust pollution. Gear drive mill barrel tumbles iron or steel balls with the ore at a speed. Usually, the balls filling rate about 40%, the mill balls size are initially 3080 cm diameter but gradually wore away as the ore was ground. In general, ball mill grinder can be fed either wet or dry, the ball mill machine is classed by electric power rather than diameter and capacity. JXSC ball mill manufacturer has industrial ball mill and small ball mill for sale, power range 18.5-800KW. During the production process, the ball grinding machine may be called cement mill, limestone ball mill, sand mill, coal mill, pebble mill, rotary ball mill, wet grinding mill, etc. JXSC ball mills are designed for high capacity long service, good quality match Metso ball mill. Grinding media Grinding balls for mining usually adopt wet grinding ball mills, mostly manganese, steel, lead balls. Ceramic balls for ball mill often seen in the laboratory. Types of ball mill: wet grinding ball mill, dry grinding ball mill, horizontal ball mill, vibration mill, large ball mill, coal mill, stone mill grinder, tumbling ball mill, etc. The ball mill barrel is filled with powder and milling media, the powder can reduce the balls falling impact, but if the power too much that may cause balls to stick to the container side. Along with the rotational force, the crushing action mill the power, so, it is essential to ensure that there is enough space for media to tumble effectively. How does ball mill work The material fed into the drum through the hopper, motor drive cylinder rotates, causing grinding balls rises and falls follow the drum rotation direction, the grinding media be lifted to a certain height and then fall back into the cylinder and onto the material to be ground. The rotation speed is a key point related to the ball mill efficiency, rotation speed too great or too small, neither bring good grinding result. Based on experience, the rotat

ion is usually set between 4-20/minute, if the speed too great, may create centrifuge force thus the grinding balls stay with the mill perimeter and dont fall. In summary, it depends on the mill diameter, the larger the diameter, the slower the rotation (the suitable rotation speed adjusted before delivery). What is critical speed of ball mill? The critical speed of the ball mill is the speed at which the centrifugal force is equal to the gravity on the inner surface of the mill so that no ball falls from its position onto the mill shell. Ball mill machines usually operates at 65-75% of critical speed. What is the ball mill price? There are many factors affects the ball mill cost, for quicker quotations, kindly let me know the following basic information. (1) Application, what is the grinding material? (2) required capacity, feeding and discharge size (3) dry or wet grinding (4) single machine or complete processing plant, etc.

wet ball mill for metal ores and non-ferrous metals wet milling

Applications: It can deal with metal and non-metal ores, including gold, silver, copper, phosphate, iron, etc. The ore that needs to be separated and the material that will not affect the quality of the final product when encountering water.

Wet ball mill is a kind of equipment which uses grinding medium and a certain amount of liquid (water or anhydrous ethanol) to grind materials. Unlikedry ball mill, wet ball mill adopts the wet grinding method.

The characteristic of wet grinding is that the material needs to be soaked in the liquid for grinding. This method can effectively reduce the chance of the material properties changing due to the temperature increase during the grinding process.

In the process of grinding, due to the different grinding materials, a proper amount of water or anhydrous ethanol will be added to the wet grinding ball mill. Steel ball and liquid participate in the grinding process together. The common ratio of steel ball, material and water in the wet grinding mill is 4:2:1. Depending on the nature of the grinding material, the actual ratio will be adjusted, and the specific ratio needs to be determined through the beneficiation test.

The working principle of the wet ball mill is basically the same as that of the dry ball mill. Both the rotation of the barrel drives the grinding medium and the material in the barrel to move together, and the purpose of grinding the material is finally achieved through the action of dropping and squeezing.

With the continuous feeding of materials, the generated pressure forces the materials that are fed first and have reached the qualified particle size to move to the discharge port of the wet grinding mill. The discharge port of the wet grinding ball mill is of the trumpet type, with a built-in screw device. The water flows out along the screw device, and the qualified materials are taken out of the ball mill at the same time.

Because there is liquid involved in the grinding process, the wet grinding mill will not produce dust during the work process, so there is no need to add other auxiliary equipment. According to the different discharging methods, wet ball mill can be divided into overflow type andgrate type ball mill. Wet grinding ball mill is suitable for the treatment of materials with high moisture content, most of the ore will not produce physical or chemical reaction when encountering water, so it is also suitable for wet grinding.

As a ball mills supplier with 22 years of experience in the grinding industry, we can provide customers with types of ball mill, vertical mill, rod mill and AG/SAG mill for grinding in a variety of industries and materials.

grinding - mineral processing

The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.

In order to separate the concentrate from the ore, the ore should be ground fine enough to release the target mineral from the non-mineral grains. The degree of grinding required for this depends on the size of the mineral particles in the ore. A laboratory-scale flotation test is usually required on materials of different particle sizes to determine the grinding particle size required to release the target minerals.The fineness of the ore particles produced by grinding is crucial to recover the minerals by flotation. The most common grinding machines are semi-automatic (SAG) and automatic (AG) mills and ball mills.

Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process.The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the bubbles, thereby reducing their ability to be recovered into the concentrate.In addition, extremely fine rock and iron sulfide particles may agglomerate with extremely fine sulfide ore particles, preventing the ore particles from floating.

According to the test, the particles usually need to be ground to a diameter of about 100 mm to release minerals from each other. When the particles are less than about 10 mm, this is not conducive to the flotation effect.Grinding operations are very power-hungry, which is another reason to avoid excessive grinding.

The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.A large vibrating screen is used to sieve the ground products to separate the oversized particles. A small cone crusher to recover the oversized material, and then sent them return to the SAG or AG mill for re-grinding. The correct size material is sent to the ball mill for final grinding.

The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.Grinding is always carried out under wet conditions, with about 70% solid mixture in water.This procedure maximizes ore production and minimizes power consumption.

small ball mills for sale

Our small-scale miners Ball Mills use horizontal rotating cylinders that contain the grinding media and the particles to be broken. The mass moves up the wall of the cylinder as it rotates and falls back into the toe of the mill when the force of gravity exceeds friction and centrifugal forces. Particles are broken in the toe of the mill when caught in the collisions between the grinding media themselves and the grinding media and the mill wall. In ball mills, the grinding media and particles acquire potential energy that becomes kinetic energy as the mass falls from the rotating shell. Ball mills are customarily divided into categories that are mainly defined by the size of the feed particles and the type of grinding media.

Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 um. This duty represents reduction ratios as great as 100.

The ball mill, an intermediate and fine-grinding device, is a tumbling drum with a 40% to 50% filling of balls. The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. Very large tonnages can be ground with these devices because they are very effective material handling devices. The feed can be dry, with less than 3% moisture to minimize ball coating, or a slurry can be used containing 20% to 40% water by weight. Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, autogenous mills, or semi-autogenous mills. Regrind mills in mineral processing operations are usually ball mills, because the feed for these applications is typically quite fine. Ball mills are sometimes used in single-stage grinding, receiving crusher product. The circuits of these mills are often closed with classifiers at high-circulating loads.

All ball mills operate on the same principles. One of these principles is that the total weight of the charge in the mill-the sum of the weight of the grinding media, the weight of the material to be ground, and any water in the millis a function of the percentage of the volume of the mill it occupies.

The power the mill draws is a function of the weight of the charge in the mill, the %of volumetric loading of the mill, the %of critical speed, which is the speed in RPM at which the outer layer of the charge in the mill will centrifuge.

For closed grinding circuits producing typical ball mill products, indirect and direct on-line measurements of the product size are available. The indirect means are those which assume that the product size is relatively constant when the feed condition to the classifying unit and the operating conditions in the classifying unit are constant. One example is maintaining a constant mass flow, pulp density and pressure in the feed to the cyclone classifier.

By using math modeling, it is possible to calculate the product size from measured cyclone classifier feed conditions and circuit operating data, thus establishing the effect on the particle size distribution in the product for changes in the variables.

Direct on-line means to measure either particle size or surface area are available for typical ball mill circuit products. These require the means to obtain representative or at least consistent samples from the grinding circuit product stream. These direct means and the calculated product particle size distributions can be used to:

Small variations in the feed size to ball mill circuits generally is not critical to the calculation of operating work index because they make a very small change in the 10F factor. Thus, a computer program can be developed to calculate operating work indices from on-line data with the feed size a constant and with the program designed to permit manually changing this value, as required to take into account changes in feed size resulting from such things as drawing down feed bins, crusher maintenance, work screen surfaces in the crushing plant, etc. which are generally known in advance, or can be established quickly. Developments underway for on-line measurement of particle size in coarser material which when completed will permit measuring the feed size used to calculate operating work indices.

recorded by a data logger, gives continuous means to report comminution circuit performance and evaluate in-plant testing. Changes in Wio indicated on data loggers alert operating and supervisory personnel that a change has occurred in either the ore or in circuit performance. If sufficient instrumentation is available, the cause for a problem can often be located from other recorded or logged data covering circuit and equipment operation, however, generally the problem calls for operator attention to be corrected.

Wio can be used to determine the efficiency of power utilization for the entire comminution section of a mill, and for the individual circuits making up the comminution section. The efficiency of a comminution circuit is determined by the following equation.

Wi is obtained by running the appropriate laboratory tests on a composite sample of circuit feed. Wio is calculated from plant operating data covering the period when the feed sample was taken. Since Wi from laboratory tests refers to specific conditions for accurate efficiency determinations, it is necessary to apply correction factors as discussed in The Tools of Power Power to Wio to put the laboratory and operating data on the same basis.

To-date, there is no known way to obtain standard work index data from on-line tests. Continuous measurement of comminution circuit efficiency is not possible and thus efficiency is not available for circuit control. Using laboratory data and operating data, efficiency can be determined for overall section and individual circuit for evaluation and reporting. Just monitoring Wio and correcting operating problems as they occur will improve the utilization of the power delivered to the comminution circuits.

Samples taken from the chips around blast hole drillings and from broken ore in the pit or mine for laboratory work index and other ore characteristic determinations before the ore is delivered to the mill, can be used to predict in advance comminution circuit performance. Test results can also be used for ore blending to obtain a more uniform feed, particularly to primary autogenous and semi-autogenous circuits.

We sell Small Ball Mills from 2 to 6 (600 mm X 1800 mm) in diameter and as long as 10 (3000 mm) in length.

All ball mills always come withOSHA-type gear guard.

A PULP level sufficiently high to interpose a bed of pulp, partly to cushion the impact of the balls, permits a maximum crushing effect with a minimum wear of steel. The pulp level of theseSmall Ball Millscan be varied from discharging at the periphery to discharging at a point about halfway between the trunnion and the periphery.The mill shell is of welded plate steel with integral end flanges turned for perfect alignment, and the heads are semi-steel, with hand holes in the discharge end through which the diaphragm regulation is arranged with plugs.The trunnion bearings are babbitted, spherical, cast iron, and of ample size to insure low bearing pressure; while the shell and saddle are machined to gauge so that the shells are interchangeable.

The CIW is a Small Ball Mill thats belt driven, rigid bearing, wet grinding, trunnion or grate discharge type mill with friction clutch pulley and welded steel shell. The 7 and 8 foot diameter mills are of flange ring construction with cut gears while all other sizes have cast tooth gears. All these mills are standard with white iron bar wave type shell liners except the 8 foot diameter mill which is equipped with manganese steel liners. The horsepowers shown in the table are under running conditions so that high torque or wound rotor (slip ring) motors must be used. Manganese or alloy steel shell or head liners and grates can be supplied with all sizes of mills if required. Alloy steel shell liners are recommended where 4 or larger balls are used and particularly for the larger sized mills.

Small (Muleback Type) Ball Mill is built for muleback transportation in 30 and 3 diameters (inside liners). A 4 (Muleback Type) Ball Mill is of special design and will be carefully considered upon request. Mankinds search for valuable minerals often leads him far away from modern transportation facilities. The potential sources of gold, silver and strategic minerals are often found by the prospector, not close by our modern highways, but far back in the mountains and deserts all over the world. The Equipment Company has realized this fact, and therefore has designed a Ball Mill that can be transported to these faraway and relatively inaccessible properties, either by the age old muleback transportation system, or by the modern airplane. As a result these properties may now obtain a well-designed ball mill with the heaviest individual piece weighing only 350 pounds.

The prime factor considered in this design was to furnish equipment having a maximum strength with a minimum weight. For this reason, these mills are made of steel, giving a high tensile strength and light weight to the mills. The muleback design consists of the sturdy cast iron head construction on the 30 size and cast steel head construction on the larger sizes. The flanges on the heads are arranged to bolt to the rolled steel shell provided with flanged rings. When required, the total length of the shell may consist of several shell lengths flanged together to provide the desired mill length. Liners, bearings, gears and drives are similar to those standard on all Ball Mills.

This (Convertible) and Small Ball Mill is unique in design and is particularly adapted to small milling plants. The shell is cast in one piece with a flange for bolting to the head. In converting the mill from a 30x 18 to a 30x 36 unit with double the capacity, it is only necessary to secure a second cast shell (a duplicate of the first) and bolt it to the original section.

30 Convertible Ball Mills are furnished with scoop feeders with replaceable lips. Standard mills are furnished with liners to avoid replacement of the shell; however, themill can be obtained less liners. This ball mill is oftendriven by belts placed around the center, although gear drive units with cast gears can be furnished. A Spiral Screen can be attached to the discharge.

This mill may be used for batch or intermittent grinding, or mixing of dry or wet materials in the ore dressing industry, metallurgical, chemical, ceramic, or paint industries. The material is ground and mixed in one operation by rotating it together with balls, or pebbles in a hermetically sealed cylinder.

The cast iron shell which is bolted to the heads is made with an extra thick wall to give long wearing life. Two grate cleanout doors are provided on opposite sides of the shell by means of which the mill can be either gradually discharged and washed, while running, or easily and rapidly emptied and flushedout while shut down. Wash-water is introduced into the interior of the mill through a tapped opening in the trunnion. The mill may be lined with rubber, silex (buhrstone) or wood if desired.

The Hardinge Conical Ball Mill has been widely used with outstanding success in grinding many materials in a wide variety of fields. The conical mill operates on the principle of an ordinary ball mill with a certain amount of classification within the mill itself, due to its shape.

Sizes of conical mills are given in diameter of the cylindrical section in feet and the length of the cylindrical section in inches. Liners can be had of hard iron, manganese steel or Belgian Silex. Forged steel balls or Danish Flint Pebbles are used for the grinding media, depending upon the material being milled.

The Steel Head Ball-Rod Mill gives the ore dressing engineer a wide choice in grinding design so that he can easily secure a Ball-Rod Mill suited to his particular problem. The successful operation of any grinding unit is largely dependent on the method of removing the ground pulp. The Ball-Rod Mill is available with five types of discharge trunnions, each type obtainable in small, medium or large diameters. The types of discharge trunnions are:

The superiority of the Steel Head Ball-Rod Mill is due to the all steel construction. The trunnions are an integral part of the cast steel heads and are machined with the axis of the mill. The mill heads are assured against breakage due to the high tensile strength of cast steel as compared to that of the cast iron head found on the ordinary ball mill. Trunnion Bearings are made of high- grade nickel babbitt.

Steel Head Ball-Rod Mills can be converted intolarger capacity mills by bolting an additional shell lengthonto the flange of the original shell. This is possible because all Steel Head Ball or Rod Mills have bearings suitable for mills with length twice the diameter.

Head and shell liners for Steel Head Ball-Rod Mills are available in Decolloy (a chrome-nickel alloy), hard iron, electric steel, molychrome steel, and manganese steel. Drive gears are furnished either in cast tooth spur gear and pinion or cut tooth spur gear and pinion. The gears are furnished as standard on the discharge end of the mill, out of the way of the classifier return feed, but can be furnished at the mill feed end by request. Drives may be obtained according to the customers specifications.

If this is true, there is significance in the factthat international Nicked and Climax Molybdenum, theworlds largest producers of two important steel alloys, areboth users of MARCY Mills exclusively. With international interest centered on increasingproduction of gold, it is even more significant that MARCYMills are the predominant choice of operators in everyimportants gold mining camp in the world.

Ball Mill. Intermediate and fine size reduction by grinding is frequently achieved in a ball mill in which the length of the cylindrical shell is usually 1 to 1.5 times the shell diameter. Ball mills of greater length are termed tube mills, and when hard pebbles rather than steel balls are used for the grinding media, the mills are known as pebble mills. In general, ball mills can be operated either wet or dry and are capable of producing products on the order of 100 pm. This duty represents reduction ratios as great as 100.

The ball mill, an intermediate and fine-grinding device, is a tumbling drum with a 40% to 50% filling of balls (usually steel or steel alloys). The material that is to be ground fills the voids between the balls. The tumbling balls capture the particles in ball/ball or ball/liner events and load them to the point of fracture. Very large tonnages can be ground with these devices because they are very effective material handling devices. The feed can be dry, with less than 3% moisture to minimize ball coating, or a slurry can be used containing 20% to 40% water by weight. Ball mills are employed in either primary or secondary grinding applications. In primary applications, they receive their feed from crushers, and in secondary applications, they receive their feed from rod mills, autogenous mills, or semiautogenous mills. Regrind mills in mineral processing operations are usually ball mills, because the feed for these applications is typically quite fine. Ball mills are sometimes used in single-stage grinding, receiving crusher product. The circuits of these mills are often closed with classifiers at high-circulating loads.

These loads maximize throughput at a desired product size. The characteristics of ball mills are summarized in the Table, which lists typical feed and product sizes. The size of the mill required to achieve a given task-that is, the diameter (D) inside the liners-can be calculated from the design relationships given. The design parameters must be specified.

The liner- and ball-wear equations are typically written in terms of an abrasion index (Bond 1963). The calculated liner and ball wear is expressed in kilograms per kilowatt-hour (kg/kWh), and when multiplied by the specific power (kWh/t), the wear rates are given in kilograms per ton of feed. The wear in dry ball mills is approximately one-tenth of that in wet ball mills because of the inhibition of corrosion. The efficiency of ball mills as measured relative to single-particle slow-compression loading is about 5%. Abrasion indices for five materials are also listed in the Table.

The L/D ratios of ball mills range from slightly less than 1:1 to something greater than 2:1. The tube and compartment ball mills commonly used in the cement industry have L/D ratios 2.75:1 or more. The fraction of critical speed that the mill turns depends on the application, and most mills operate at around 75% of critical speed. Increased speed generally means increased power, but as the simulations presented in Figure 3.26 show, it can also produce more wasted ball impacts on the liners above the toe. causing more wear and less breakage.

There are three principal forms of discharge mechanism. In the overflow ball mill, the ground product overflows through the discharge end trunnion. A diaphragm ball mill has a grate at thedischarge end. The product flows through the slots in the grate. Pulp lifters may be used to discharge the product through the trunnion, or peripheral ports may be used to discharge the product.

The majority of grinding balls are forged carbon or alloy steels. Generally, they are spherical, but other shapes have been used. The choice of the top (or recharge) ball size can be made using empirical equations developed by Bond or Azzaroni or by using special batch-grinding tests interpreted in the content of population balance models. The effect of changes in ball size on specific selection functions has been found to be different for different materials. A ball size-correction method can be used along with the specific selection function scale-up method to determine the best ball size. To do this, a set of ball size tests are performed in a batch mill from which the specific selection function dependence on ball size can be determined. Then, the mill capacities used to produce desired product size can be predicted by simulation using the kinetic parameter corresponding to the different ball sizes.

The mill liners used are constructed from cast alloy steels, wear-resistant cast irons, or polymer (rubber) and polymer metal combinations. The mill liner shapes often recommended in new mills are double-wave liners when balls less than 2.5 in. are used and single-wave liners when larger balls are used. Replaceable metal lifter bars are sometimes used. End liners are usually ribbed or employ replaceable lifters.

The typical mill-motor coupling is a pinion and gear. On larger mills two motors may be used, and in that arrangement two pinions drive one gear on the mill. Synchronous motors are well suited to the ball mill, because the power draw is almost constant. Induction, squirrel cage, and slip ring motors are also used. A high-speed motor running 600 to 1,000 rpm requires a speed reducer between the motor and pinion shaft. The gearless drive has been installed at a number of locations around the world.

Mineral processing is the most important link in the entire production process of mineral products. It is a process of separating useful minerals from useless minerals (usually called gangue) or harmful minerals in a mineral raw material by physical or chemical methods, or a process of separating multiple useful minerals The process is called mineral processing, also known as ore processing.

The first step in the ore processing is to select the useful minerals. In order to select useful minerals from ore, the ore must be crushed first. Sometimes, in order to meet the requirements of subsequent operations on the particle size of materials, it is necessary to add a certain ore grinding operation in the process.

The preparation before beneficiation is usually carried out in two stages: crushing screening operation and mineral classification operation. Crusher and ore ball mill are the main equipment in these two stages.

wet grid ball mill

Grid ball mill is widely used in smashing all kinds of ores and other materials, ore dressing and national economic departments like building and chemical industries etc. The size of ore shall not exceed 65mm and the best feed size is under 6mm. The effect in this job is better than coarse grinding. Grid ball mill consists of the shell, feeding part, discharging part, main bearing, lubricating system, driving system and other parts. There is wearing a liner inside the shell, and both ends of the shell are provided with a flange. The end cover of the mill is connected with the flange plate. The feeding part consists of the head, trunnion and feeding device. The discharge part includes the grid plate, head, and discharge trunnion.

Wet Grid ball mill is mainly used for mixing and grinding materials in two types: dry grinding and wet grinding .It has advantages of fineness uniformity and power saving. The machine uses different types of liner to meet different customer needs. The grinding fineness of material can be controlled by grinding time. The electro-hydraulic machine is auto-coupled and decompressed to reduce the starting current, and its structure is divided into integral type and independent type.

Compared with similar products,Wet Grid ball mill has the characteristics of low investment, low energy consumption, novel structure, simple operation, stable and reliable performance. It is suitable for mixing and grinding ordinary and special materials. The users can choose the right type, liner and medium type by considering the specific gravity, hardness, yield and other factors. The grinding medium is Wet Grid ball.

1.The ball mill is composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The main body is a long cylinder made of steel. The cylinder is provided with an abrasive body, and the steel lining plate is fixed to the cylinder body. The grinding body is generally a steel ball and is loaded into the cylinder according to different diameters and a certain proportion, and the grinding body can also be used with a steel section.

2.According to the particle size of the grinding material, the material is loaded into the cylinder by the hollow shaft of the wet grid ball mill feeding end. When the ball mill cylinder rotates, the grinding body acts on the cylinder liner due to the action of inertia and centrifugal force and friction. It is carried away by the cylinder. When it is brought to a certain height, it is thrown off due to its own gravity. The falling abrasive body crushes the material in the cylinder like a projectile.

3.The material is uniformly fed into the first chamber of the mill by the feeding device through the hollow shaft of the feeding material. The chamber has a step liner or a corrugated liner, and various steel balls are loaded therein. The rotation of the cylinder generates centrifugal force to bring the steel ball to a certain extent. The height drops and then hits and grinds the material. After the material reaches the rough grinding in the first bin, it enters the second bin through the single-layer partition plate. The bin is embedded with a flat liner with steel balls inside to further grind the material. The powder is discharged through the discharge raft to complete the grinding operation.

The main function of the steel ball in the ball mill is to impact crush the material and also play a certain grinding effect. Therefore, the purpose of grading steel balls is to meet the requirements of these two aspects. The quality of the crushing effect directly affects the grinding efficiency, and ultimately affects the output of the ball mill. Whether the crushing requirement can be achieved depends on whether the grading of the steel ball is reasonable, mainly including the size of the steel ball, the number of ball diameters, and the ball of various specifications. Proportion and so on.

The ball mill is composed of the main part such as a feeding part, a discharging part, a turning part, a transmission part (a reduction gear, a small transmission gear, a motor, and electric control). The hollow shaft is made of cast steel, the inner lining can be replaced, the rotary large gear is processed by casting hobbing, and the barrel is embedded with wear-resistant lining, which has good wear resistance. The machine runs smoothly and works reliably.

ball mill explained - savree

Ball mills are employed in the comminution stage as grinding machines (size reduction). The purpose of grinders in the mining industry is to reduce the feed material size in order to liberate the minerals from the barren rock. Ball mills are the most common grinding machine employed in the mining industry.

Grinding occurs in a single stage, or multiple stages. Multiple stages may include a rod mill followed by a ball mill (two stage circuit), or a semi-autogenous grinding (SAG) mill followed by a ball mill (two stage circuit). Smaller plants tend to add extra crushing stages in order to operate a single grinding stage only.

The following process description is based upon a ball mill used in the hard rock mining industry for liberating minerals from ore, but the operating principle for ball mills used in other industries is the same.

For both wet and dry ball mills, the ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drums volume so that the total volume of the drum is 50% charged. Pulp is usually 75% solid (crushed ore) and 25% water; pulp is also known as slurry.

An electric motor is used to rotate the ball mill. As the ball mill rotates, the balls stick to the inner surface of the drum due to the centrifugal force created within the drum. At a certain angle, the weight of the balls overcomes the centrifugal force holding them against the drum and they begin to tumble back to the centre line of the ball mill (this area is known as the toe). In this manner, the ore is reduced in size by both attrition (ore rubbing against other bits of ore) and impact (balls impacting with the ore).

The ore moves gradually through the mill then exits through the discharge port. The discharge port may be covered by a grate to prevent oversized ore exiting the mill, or it may have no grate (overflow type ball mill).

Ball mills may operate in a closed-circuit, or open-circuit. Closed circuits return a certain amount of the ball mills output back to the ball mill for further size reduction. A typical closed system grinds the ore between two to three times.

Hydro-cyclones installed directly after the ball mill ensure only over-sized material is returned to the ball mill. Other types of classifiers can be used (rake and spiral classifiers), but the hydro-cyclone is now one of the most common.

Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble.

Most ball mills operate at approximately 75% critical speed, as this is determined to be the optimum speed. The true optimum speed depends upon the drum diameter. Larger drum diameters operate at lower than 75% critical speed whilst smaller drum diameters operate at higher than 75% critical speed.

Irrespective of the type of grinding machine employed, grinding is a low efficiency and power intensive process. For this reason, the grinding stage of a mineral processing plant may account for up to 40% of total operating costs.

As a general rule of thumb, the larger the diameter of the ball mill drum, the more efficient the grinding process will be. This rule of thumb stops though once the diameter of the drum reaches approximately 4m (13.1 feet).

wet pan mill gold mining - crushers, ball mills and flotation cells for mining and mineral beneficiation

CGN wet pan mill gold mining also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator.

1. The Application of Wet Pan Mill gold mining CGN wet pan mill also called wet gold grinding machine is used for amalgamation gold extraction of sulfide-free gold mines and is suitable for operations in field areas without power supply by equipped with a diesel generator. This machine, which has functions of crusher and ball mill, can crush the ores once for all in the purpose of gold extraction in amalgamation method.

3.Working principle of Wet Pan Mill The diesel generator is responsible for power supply in operation. The reducer and the interlocked main shaft are driven via the belt to run the grinding wheel and grind the ores. When crushed to 0.05-1mm, the ores are added for mercury cycle operations. When extracting mercury cream, the machine should be stopped.

4. Principle of Amalgamation for gold Amalgamation method is to extract gold particles in the ores. When crushed to 0.05-1mm grain size or more, most of the gold particles can be separated and drift in the water. The gold particles in 0.05mm-1mm grain size are surrounded by mercury, and compound reaction occurs to generate mercury paste of AuHg2, Au2Hg and Au3Hg, which is also known as gold amalgam. Since gold and silver are usually associated, there is silver in the mercury paste in addition to gold, and is separated from other metallic minerals. The amalgamation process takes place under the infiltration effect of water, gold and mercury. The recovery of gold depends on grinding size, cleanliness of gold particle, ore pulp concentration, temperature, and pH value. To save the consumption of mercury, the ores are usually ground to 0.05-1mm before added to mercury. The mercury per ton of ore depends on the grade of raw ores. 2% of lime should be added to reduce the viscosity of the ore pulp, the pH value of the ore pulp should be adjusted to PH8-9, and the concentration should be in 30%-40% for amalgamation operations. After amalgamation, water is added to dilute the ore pulp for mercury deposition and accumulation. The mercury paste can be recycled after the gold particles treated and removed.

6.Installation, Usage and Maintenance 1. The machine should be installed on a concrete foundation, placed on level and the anchor bolts should be tightened. 2. Operation steps: Shift the clutch handle to ON position to start the diesel generator. Engage the clutch to drive the host when the operation is normal, and feed materials and water for operation. Disconnect the clutch to stop the machine before cleaning up the mercury paste. 3. Add water, engine oil and diesel oil to the diesel generator on regular basis. See the instructions for details. Lubricate the clutch and upper bearing cover once and add engine oil into reducer once every 30 days. 4. The power section should be kept from sunlight and rain, and ore pulp infiltration to be avoided in operation.

ZJH mainly focus on producing and supply crushers, ore grinding equipment, mineral Beneficiation equipment, laboratory and pilot scale ore dressing equipment for Mining and Mineral Processing Industry. Our aim is to work together with Mines, Mineral Beneficiation Plantsfor helping to reduce the operating cost ,to improve the operating efficiency.

ball mill - easystudypoint

Ball mill is that the key machine to grind the crushed materials. The ball mill machine is wide accustomed method cement, salt product, building material, refractory material, fertilizer, ceramics, and glass, etc. The ball mill, also known as the rod mill, will work in a dry manner or wet way. you choose the operating way of a little ball mill machine according to your material and discharging way.

The work of a wet type ball mill wants water, adding water throughout the grinding work, and its primarily utilized in mineral dressing line. A wet-type ball mill will grind ores into pulp, then the pulp may be separated by magnetic separators or flotation cells.According to the distinction of raw materials, Fote produces the subsequent ball mills: gold ore ball mill machine, metallic element ore ball mill machine, nickel ore ball mill machine, tin ore ball mill machine, copper ore ball mill machine, mineral ball mill machine, andalusite ball mill machine, aluminum ash ball mill machine, molybdenum ball mill machine, and fluorspar ball mill machine.Since people have completely different demands toward ball mill like structure, technology, and working way, Fote produces the subsequent kinds: overflow ball mill, high-efficient, and energy-conserving ball mill, tube mill, wet ball mill, intermittent ball mill, cement ball mill, ceramic ball mill, and cone ball mill, etc.

Through feeder and hollow shaft spiral, raw materials are equally delivered into the primary bin, that has stepped lining plates and completely different steel balls inside. once the drum moves, centrifugal force is created and brings steel balls to a particular height. Then, steel balls suddenly drop to hit or grind raw materials. when being coarsely ground within the first bin, raw materials are delivered into the second bin through the single-wall partition. during this bin, there are flat linear plates and steel balls, which might any grind materials. The finished powders are finally discharged out via grid plate.

The high-pressure air blower constantly inhales air at intervals the grinding mill and, in turn, the airflow with crushed materials are delivered to the classifier whose high-speed vane can screen the airflow: the unqualified particle size will fall and come back to the mill for being reground whereas the qualified particle size mixed with air will move into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a tiny low proportion of the fine powders, with airflow, moves to the mud cleaner and clings to the surface of the filter bags. At constant time, the fine powders clinging to the surface crumple by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the heartbeat valve. The materials from on top of 2 heaps are sent by the conveyor at an all-time low to induce finished powders packed. In addition, filtered clean air is emitted from the air outlet of the muffler within the end.

grinding cylpebs

Our automatic production line for the grinding cylpebs is the unique. With stable quality, high production efficiency, high hardness, wear-resistant, the volumetric hardness of the grinding cylpebs is between 60-63HRC,the breakage is less than 0.5%. The organization of the grinding cylpebs is compact, the hardness is constant from the inner to the surface. Now has extensively used in the cement industry, the wear rate is about 30g-60g per Ton cement.

Grinding Cylpebs are made from low-alloy chilled cast iron. The molten metal leaves the furnace at approximately 1500 C and is transferred to a continuous casting machine where the selected size Cylpebs are created; by changing the moulds the full range of cylindrical media can be manufactured via one simple process. The Cylpebs are demoulded while still red hot and placed in a cooling section for several hours to relieve internal stress. Solidification takes place in seconds and is formed from the external surface inward to the centre of the media. It has been claimed that this manufacturing process contributes to the cost effectiveness of the media, by being more efficient and requiring less energy than the conventional forging method.

Because of their cylindrical geometry, Cylpebs have greater surface area and higher bulk density compared with balls of similar mass and size. Cylpebs of equal diameter and length have 14.5% greater surface area than balls of the same mass, and 9% higher bulk density than steel balls, or 12% higher than cast balls. As a result, for a given charge volume, about 25% more grinding media surface area is available for size reduction when charged with Cylpebs, but the mill would also draw more power.

Individuals who have ever been in a processing plant in which hard material are ground into fine powder may have heard of a ball mill, but most people wonder, what is a ball mill? A ball mill is a type of device that is used for grinding and turning the material into very fine powder. They are cylindrical and they are mostly used in mashing paints, ceramic materials, ores and hard chemicals. The ball mill is rotated on an axis that is horizontal and this is how it is able to convert the material into very loose powder.

A ball mill usually has a grinding material which could be stainless steel balls, ceramic balls or even flint pieces. These balls are necessary for the ball milling process because when they grind against another material, this material is crushed into fine powder.

When asking what is a ball mill, it is important to also know how it works. The ball mil is usually operated by a machine, which feeds the materials to be ground through one end, and it is passed through the milling balls and out of the other end as fine loose powder. Most ball mills use balls made of stainless steel because steel can pulverize most materials, though a disadvantage is that steel cannot be used with materials that are flammable or sensitive. In such cases, ceramic and flint balls replace steel in the ball mill.

Ball milling processrefers to the process of grinding materials of different kinds into powder using a ball mill. This process is usually undertaken in the building industry, in the chemical industry and in the mining industry. There are two major types of processes which are the dry and the wet processes.

Examples of materials that ground using a ball mill are cement, fire proof material, non-ferrous metals, ceramics, glass, black metal, cement and silicate products. The equipment has a horizontal type as well as tubular running devices with two warehouses. The outside of the machine runs across a gear. The material to be milled enters evenly through the first warehouse of the ball mill along the input hollow axis. There are different types of steel balls and when the body of the barrel rotates, it produces centrifugal force. The steel balls are carried to a certain height and then they fall, thus grinding the material.

After the material has been ground to a coarse powder in the first warehouse, the coarse powder enters the second warehouse where it is reground with the steel balls into finer powder and ultimately, the fine powder is released at the end through the output board and this is what marks the end of the ball milling process.

Mineral milling is the process of grinding minerals into a fine powder. It is different from the process of granulation or crushing which is about the reduction of the size of a mineral to the size of a grain. Before milling a mineral, it is important to first determine its characteristics which include its hardness, brittleness, toughness, stickiness, melting or softening temperature, structure, abrasiveness, chemical stability, purity, homogeneity, free moisture content and structure.

The hardness of the mineral determines the specialization as well as cost of the type of mill that will be used. Brittleness is the ease with which a material will break. The free moisture content of a mineral should be low in order to ensure that the milling process takes place without any problems while the size and the degree of fineness of the mineral is required in order to know which mill to use.

There are various types of mills that can be used in the milling process including roller mills, hammer mills, pin mills, turbo mills, ball mills and vibrating mills. Each type of mill has different features and it is suitable for milling minerals with specific characteristics. For example, autogenous mills mill minerals that are fairly coarse into products that are relatively fine.

Mineral milling is not an easy task as many people perceive. There is a lot that is required to add up to give required end results and these services are offered by professionals that are well conversant with the milling business. There are things you need to consider if you are looking for good mineral milling services company.

All over the world there are specific companies that are known over the years of good mining services. Most of these companies have been listed in the mining website and better still they are listed in their own websites. They have all important information that is required to be seen by the client who is looking for the services.

To get good mineral milling services you need to compare many different companies and also looking around for those companies that have had good experiences with such companies. The mineral milling business requires you to get a good company since the mining takes a long period of time.

Once you have chosen a company you need to take a look at the machinery they intend to use. For one they need to be able to consume a less power and also mill in large volumes. Milling services that are recommended should be able to give you warranty of the machinery they are using and also provide the best engineers to maintain your machinery and also staff that will operate the machines to the required standards.

Mining of substances like minerals is usually done on a large scale and from many meters underneath the ground. The material mined are very heavy and brining them up in this status could require a lot of very heavy machines and in most cases they cant with stand the weight so they spoil fast. Technology has made al this easier by providing milling options and its called mineral milling.

Mineral milling is whereby grinding machines are used to grind the raw materials to finer forms for easy transport. Also even for easy means for transforming to an end product. This process is reversible to those particles that are not fine enough. Solid matter are ground using string mechanical forces that are used to trench internal forces that are holding the material together and break them. There are other grinding mineral millings that are used to produce manufacturing products.

Mineral milling is mainly done by large companies since it requires a lot of big machineries which are very expensive to purchase as an individual. These machines are usually transported in pieces and then they are reassembled at the plant where they will be used to grind. Each machine has a manual to help determine how each material can be grinded. This is because different rotation power is required to be used. Different mediums are also used to grind different raw materials. All these requires trained personnel to ensure the machines are working and are well maintained.

Planetary ball millis a type of cylinder that is used to grind materials into small particles. There are other materials that are ground and there are mediums that are used to make the process successful and complete. These machines are the latest technology that has been modified to use lees power and also give mass production. There are both large machines that rotate on their axis and small ones that sit on drive shafts.

Planetary ball mill consume less space since they are smaller and they are mostly used in laboratories. They grind sample material right down to the smallest particles. They include a grinding jar which can be more than one that is arranged eccentrically on a wheel which moves in a different direction from the grinding jars. Coroilis forces are the rotational movements which are found in the grinding jars. The speeds that run the balls inside the mills produce an interaction between impact forces and frictional forces. They release high dynamic energy making the products grind to form fine powder as end product. Reaction rate is increased by the operator depending on how fast the product is needed and also the volume. These machines are normally expensive but they are really safe to use in laboratories. Shipping arrangements can be made with the manufacturers to ensure the planetary ball mill gets to you in one piece however you could be forced to foot the extra charges.

Machinery in most cases is used to manufacture an end product and mineral ball mills are used for the same purpose by grinding. Machines have different mechanism on how they work so that the end product can be achieved. Its important for any one who intends to buy mining machine to know how mineral ball mills work.

The cylinder either rotating on its axis or using a cylindrical container rotates at a relatively low speed. This is to allow the balls to cascade or move in the mill base and allowing for the grinding of the material to occur. The rotation according to engineers should happen at twenty revolutions per minute which is highly determined by the diameter of the mill. If the diameter is large then the rotation is slower.

A closed system is preferred to operate the mineral ball mills so as to achieve reasonable efficiency. Over size material is usually and continuously re circulated back to be reduced and the discharge from the ball mills are usually classified using screens, cyclones and air classifiers. To grind the materials to finer powder the speed is usually increased especially if the machinery is using electricity and not fuel to power. This is because controlling becomes easy. there are mineral balls that are used to grind cement and these are usually large and they consume a lot of fuel or electricity Machinery in most cases is used to manufacture an end product and mineral ball mills are used for the same purpose by grinding.

A ball mill mineral machine or a grinder is used in mines to grind material into a fine powder. The grinded materials are in turn used in mineral dressing process such as pyrotechnics, paints and ceramics. It mixes materials like ores and even ceramic raw materials by rotating in a round horizontal axis. The mills are filled half way with the material to be grinded and the grinding medium or product is also put.

There are different sizes of ball mills and the large ones are the ones that rotate on their axis while the smaller ones consisting of a cylindrical container, normally sits on two drive shafts. To transmit the rotary motion using pulley and belts and in different occasion a rock tumbler is also used.

A ball mill mineral can be used to grind both wet and dry products and there are two types of ball mills namely over fall type and grate type depending on the different ways they discharge materials. There are also many types of grinding media and there properties are density, size, composition and hardness.

There is ball mill mineral that is commonly used in laboratories and are called planetary bill mill. They are used to grind materials into smallest size while giving a demonstration to students or manufacturing something by professionals.

Usually there is a defined market where you can find different machinery depending on the tasks they perform. Bill mall machines are usually used for mining and this means these are real huge machinery by size. Finding a sale store for them could cost you a lot of money since they will occupy a big space. Unless the machinery can be viewed from the go down there should be other places where one can find mineral ball mill sale.

Manufacturing companies have had to adapt to technology to ensure their products awareness reaches to their far customers as well. Today the technology has come as close to our living rooms. This means technology such as the internet and television could easily get you what you are looking for. Internet is a good place to start looking for mineral ball mill sale.

Most manufacturing companies have a website that they use to advertise their mineral bill mall sale. They place the photos of their machineries depending on the different models they manufacture. They have made the work easier for their clients by giving a detailed description of the machine so that you can have the correct information while making your decision. You will find these companies giving out sale of their products at given periods of the year. This means one can save and buy the machine when there is a sale and save a lot of money in the process.

A ball mill is a machine that is filled with materials and the rotated to grind the material into fine powder. The material that is ground is used in pyrotechnics, ceramics and paint. The main reason behind grinding materials is that increases the rate at which the ground material will react with other materials. If you want to make a quality fine material back at home, you need a ball mill. Note that when using ball mill, it may explode especially if you are using volatile materials. As such, you need to be cautious. The materials needed for making the ball mill is readily available, you need a motor, container and a roller. Constructing the mill is very simple; just make sure that the container is placed on the roller with two wheels. Then place a copper rod through the container which will be driven by the motor wheel on the right. This simple ball mills how to build guideline can be found on various websites. Note that the mill is dangerous, as such, you need to be cautious as you are using it.

what is ball mill | how many types of ball mills | m&c

Ball mill is a very important mineral grading equipment, which is indispensable for mineral processing, building materials, metallurgy and chemical industry. With the need of market, a variety of different types of ball mills have emerged. According to different standards, there are many types of ball mills.

1. Short Cylinder Ball Mill: The ball mill with the cylinder length (L) less than 2 times of the cylinder diameter, i.e. the ball mill with L 2D is short cylinder ball mill, which is usually of single bin structure, mainly used for rough grinding or primary grinding operation, and can realize the wide use of 2-3 ball mills in series.

3. Gravel Mill: The grinding medium mainly includes pebble, gravel, sand, porcelain ball, etc. Most of the gravel mills use porcelain or granite as lining plates, which are widely used in the production of color cement, white cement, ceramics and other fields.

1. Tail Discharge Mill: The head and tail of tail discharge mill are used as the inlet and outlet of materials. When the mill is working, the material is fed from the inlet end and discharged from the other end.

2. Middle Discharge Mill: The inlet of the middle discharge mill is at both ends, and the outlet is in the middle of the mill. Generally, materials are fed from both ends and then discharged from the middle of the cylinder.

1. Center Drive Ball Mill: The drive power device is in the center of the fuselage, and the motor realizes the operation of the ball mill through the reducer. In operation, the hollow shaft in the center of the ball mill drives the grinding body to rotate under the drive of the power system.

1. Wet Type Ball Mill: Water is added at the same time of feeding, and the material is discharged into a certain concentration of slurry. In the closed-circuit system, it forms a closed-circuit operation with the hydraulic grading equipment.

1. Vertical Ball Mill: The vertical ball mill is a new type of ball mill which places the cylinder upright. Through a large number of experiments, it is found that the vertical ball mill has the advantages of high grinding efficiency, low energy consumption and low noise.

2. Horizontal Ball Mill: The horizontal ball mill is used for grinding and dispersing under the closed condition to prevent solvent volatilization. It is especially suitable for fine grinding and mixing of high-purity materials.

ball mill for grinding calcium carbonate - calcium carbonate ball mill

Ball mill grinder is usually used to grind crushed materials, such as ores, chemicals, ceramic raw material and others. This article mainly talks about ball mill for grinding calcium carbonate.

Besides, Daswell ball mill machine for calcium carbonate is also the symbol of high technology, which consumes less energy and produce quality finished ground calcium carbonate powder.

Ball mill is a hollow cylinder which rotates about its axis. The axis can be horizontal or be at some angle to the horizontal. The shell of ball mill can be made of strong steel and coated with refractory materials. Ball mill is partially filled with free moving media balls which can be made of steel, stainless steel, ceramic or rubber. And the media balls are in different sizes: smaller grinding balls for fine calcium carbonate and larger media balls for coarse calcium carbonate. For the internal side, the inner wall of the ball mill is often lined with abrasive-resistant materials such as steel or rubber. And the length and diameter of ball mill grinder for calcium carbonate can come in different sizes according to production capacity.

Industrial ball mill machine for ground calcium carbonate often can operate continuously. And the raw material such as limestone or marble is fed from one end and discharged from another end. When the calcium carbonate ball mill starts to rotate under the function of drive, the media balls inside the ball mill will be lifted and then impacted against the calcium carbonate material bed. Through constant rotation, the raw material in the ball mill will be ground to medium and fine sizes. And then the ground calcium carbonate will be transported pneumatically to classifier. In the classifier, while the calcium carbonate powder of required sizes will be transported to product silo, the coarse ones will be returned to ball mill with feed material.

Ball mill and classifier often work together for calcium carbonate process. Although ball mill grinder for calcium carbonate can grind calcium carbonate material to medium and fine particle sizes, to meet customers needs of consistent fine and ultra fine GCC powder, calcium carbonate ball mill must work together with primary and even secondary classifiers. After the grinding process in calcium carbonate ball mill, the ground calcium carbonate will be transported to classifier pneumatically. The air flow in classifier will then transfer fine calcium carbonate powder to product silo, while the coarse calcium carbonate will return to ball mill together with feed material. For ultra fine ground calcium carbonate powder, a secondary classifier can be installed, forming a series circus with the primary classifier. In all, to produce uniform fine and ultra fine calcium carbonate powder in large quantity, calcium carbonate ball mill and classifying production line is the most suitable solution.

how to improve ball mill performance

Application of value engineering techniques to grinding process modelling led to the identification of two basic functions of the ball mill-classifier circuit. In terms of a specified circuit product size which is used to differentiate between coarse or oversize material and fines or undersize material, these basic functions are (a) breakage of the coarse material and (b) removal of the fines. It was proposed that it may be useful to relate circuit design and operating variables to these basic circuit functions, which although related, are conceptually quite distinguishable. If each could be quantified by a suitable parameter, then either or the two together may be correlated to overall circuit efficiency, and hence used to link individual design and operating variables to overall circuit performance.

Major design and operating variables in closed circuit ball milling of a specified feed to a desired product size are summarized in Table 1. The purpose of process modelling is to establish cause and effect relationships between physical design and operating variables and the performance objectives of the circuit. Subsequently, output and efficiency can be maximized. The fundamental issue addressed by ball mill circuit modelling is thus depicted in Figure 1 (McIvor, 1989).

In the simplest form of plant experimentation, a key performance parameter (such as the fineness of the final product) is measured with and without a specific change to the circuit. Within the constraints imposed by the accuracy of measurements and assumptions about the constancy of other inputs (including the ore characteristics), the relative values of this parameter are used to evaluate the effect of the change on circuit performance.

Bond work index analysis takes this method of experimentation several steps further. During comparative testwork, variations in the ore grindability, grinding energy input, and feed and product sizing are measured and accounted for through the grinding circuit model embodied in the work index formulation. For each set of data, both the circuit operating work index and the laboratory test work index of the circuit feed are determined. Relative work index efficiencies with and without the change to the circuit can then be calculated and compared.

Consider a ball mill circuit processing material of a given feed size and at a given throughput rate to a target product size, the latter which once again distinguishes the fines from the coarse material. The production rate of fines or new product size material can be calculated from the circuit feed and product size distributions and the throughput rate of the circuit. Based on the energy expended in the ball mill, the production rate of new product size material (tonnes/h) equals the amount produced per unit of energy applied (tonnes/kwh) times the rate at which energy is applied (kwh/h). The rate at which energy is applied is the power draw of the ball mill. If we then define the production per unit, of energy applied as the energy specific production rate of the circuit, then we can write the following equation:

All the production of new product size material takes place in the mill as coarse is ground into fines. However, the proportion of the total mill power applied to size reduction of coarse particles is equal to the fraction of coarse solids inventory, or the so defined circuit classification system efficiency.

The mill specific grinding rate reflects both the efficiency of the mill environment in breaking the coarse particles, as well as the grindability characteristic of the ore over the particular size reduction range.

To arrive at a term which reflects only the efficiency of the mill environment, we must factor out the grindability of the ore, such as the net grams per revolution measured in a Bond work index test. This will yield the specific grinding rate in the plant ball mill relative to the measured specific grinding rate in a standard test mill, and may be termed the grinding rate ratio.

The grinding rate ratio may be considered dimensionless because each revolution of the test mill requires a fixed amount of power. It is based on breakage of only the coarse material in both the plant ball mill and the standard laboratory test mill. It is therefore proposed that the grinding rate ratio is a direct measure of the relative overall breakage efficiency of the environment of the plant ball mill.

The above described parameters for system breakage and classification system efficiency factor the overall task of the ball mill circuit into its two distinct basic functions, namely, fines generation and fines removal. The effect of design and operating variables on each can be studied separately, and when the product of the two is maximized, maximum overall circuit efficiency will be achieved. Equation 2 may be re-written as:

This has been termed the ball mill circuit functional performance equation (McIvor, 1989). It states that the output of new product size material of a ball mill circuit with a given feed size is determined by:

a. the total mill power draw; b. the classification system efficiency, which defines the fraction of the total mill power effectively applied to the grinding of coarse material; c. the grindability characteristic of the ore over the size reduction range of the circuit; and, d. the breakage efficiency of the ball mill environment on the coarse material.

While all four factors clearly influence the circuit output, overall circuit efficiency will be determined by classification and breakage efficiency. Specific design and operating variables can now be considered in terms of their individual effects on classification and breakage efficiency, and subsequently on the overall efficiency of the circuit. This provides an intermediate level of ball mill circuit performance characterization, as shown in Figure 5.

ball mill | industry grinding mill - mineral processing

The ball mill is a tumbling mill that uses steel balls as grinding media. Ball mills can be used in wet or dry systems for bulk and continuous milling, and are most widely used in small or large-scale beneficiation plant.The feed can be dry with a water content of less than 3% to minimize the coverage of the ball, or it can be a slurry with a water content of 20-40%. The ball mill can be used for primary or secondary grinding applications. In the primary application, they receive feed from the crusher, and in the secondary application, they receive feed from the rod mill, autogenous mill or semi-autogenous mill.

Main partsThe mill includes motor, reducer, slow drive, power distribution control cabinet, feeding device, main bearing, rotary part, discharging device, transmission part, lubrication system (mainly including high-pressure pump station and low-pressure thin oil station) and other parts.The main working part of the ball mill is a rotary cylinder mounted on two large bearings and placed horizontally. The cylinder body is divided into several compartments by a partition plate, and a certain shape and size of grinding body is installed in each compartment. The grinding bodies are generally steel balls, steel forgings, steel rods, pebbles, gravel and porcelain balls. In order to prevent the barrel from being worn, a liner is installed on the wall of the barrel. The length of a cylindrical shell is usually 11.5 times the diameter of the shell.The grinding elements including grinding media and material in the ball mill move at different speeds. Therefore, the collision force, direction and kinetic energy between two or more elements vary greatly in the ball charge. Friction and wear or friction and collision energy all act on the particles. These forces come from the rotating motion of the ball and the particle motion in the mill and the contact area of the collision ball.
