how to select grinding media for your application

Grinding machinesuse friction, attrition, or compression to smooth out a metal products surface. There are several types of grinding machines designed to deliver different levels of finite smoothness. For example, a ball-grinding mill is an excellent fine grinder for cement products, but may not work for more extensive smoothing projects.

Most metal grinding machines consist of a substrate within a rotating drum. Rod mills are used to make metal rods, while semi-autogenous grinding (SAG) mills and autogenous grinding mills smooth copper, gold, platinum,and silver.

Vibratory finishing machines deburr products and remove sharp edges. They position material inside a drum filled with abrasive pellets and a substrate, then apply a tumbling vibration to create a uniform random texture. The machines cycle speed and magnitude of vibration are usually variable, allowing effective treatment for a range of small- to large-sized parts.

Grinding media comprises a range of objects. Grinding balls, beads, satellites, cylinders, diagonals, and ball-cones are all different shapes of abrasives. The media itself can be made up of a variety of materials, such as carbon steel, stainless steel, chrome steel, and non-metallics like ceramics or steatite.

The initial feed size matters because smaller media cannot easily break up large particles, so it shouldnt be used for large particle applications. Similarly, the final particle size should be considered, as smaller media is more efficient when ultrafine particles are anticipated.

In general, high-density media give better results. The media should be denser than the material that is being ground. Also, highly viscous materials need media with a higher density to prevent floating. The specific gravity of grinding media is therefore essential to consider.

The harder the media, the higher the grinding competence and the longer the wear. Some of the harder grinding medias are made of hardened steel, tungsten carbide, agate, and zirconia. The overall abrasiveness should also be taken into account. If a highly-abrasive media is put into a grinding chamber that isnt equally abrasive, not only will the media not be adequately ground, there is a risk of lasting damage to the chamber.

Some media may cause a lighter-colored slurry to turn gray, so be aware of potential discoloration. As well, some strong acid or basic slurries may react with metallic media, and therefore a nonmetallic such as ceramic should be used. Iron media, for example, may react with corrosive materials. Options for use with corrosive substances are stainless steel, ceramic, and flint grinding media.

In the grinding process, the media is obviously subject to wear. Any material that results from the wear of the media may disturb the product and should be eliminated with a magnetic separator, chemicals, or other means.

Although more critical with smaller media, the ideal is consistently-sized media. In these small sizes, there are ranges because, due to the manufacturing process, the media must be classified or screened. When perfectly spherical grinding media is used in a mill, all gaps that form will be the same size. Once the media is no longer spherical or is differently-sized, the force of the fluid or powder is not exerted equally. This can cause media to tumble in the mill, resulting in some gaps, both large and small. The liquid in the premix material then naturally flows more through the larger gaps. The shear force is then not high enough to do any deagglomeration, and the mill efficiency suffers.

Tungsten carbide and zirconia milling media are more expensive and may last considerably longer, and therefore, will be well worth the extra cost over the long run. Of course, no grinding media is invulnerable to wear, and eventually, all media will need to be replaced. That said, purchasing more expensive grinding media with a long lifespan may help maintain and replacement costs. Exceptionally durable media can help with costs in the long run.

As most of the work in many grinding mills such as a ball mill,horizontal mill, or vertical mill, is done by squeezing the material through the gaps between the media, this means that the more gaps, the more successful the milling. To increase the number of gaps, the number of beads or cylinders should be increased. However, to maintain the amount of media that is loaded, the only option is to decrease the size of the media for example, the diameter of the beads.

This article explains the importance of choosing the correct grinding media for your application. Different materials require different media.

how to select grinding mill liner alloys for optimum wear resistance

The wear resistance of an alloy in heavy mill liner sections may be quite different from that of the same alloy in small balls and other light sections. This fact was established by means of a well standardized laboratory test that was validated for ball mill service. The salient properties of mill liner alloys, including austenitic manganese steels, medium alloy hardenable steels, and abrasion resistance cast irons are described, critically compared, and quantitatively ranked in terms of mill liner service.

Where they are tough enough the high-chromium and other martensitic cast irons (e.g. Ni-Hard) promise maximum economy, but their section sensitivity is a limitation. To overcome this an extensive research program studied over a hundred experimental alloys, ranking them for heavy section abrasion resistance by means of the laboratory test.

There is a widespread tendency to accept hardness as an index of abrasion resistance. Most hardness tests provide a measure of compressive strength, e.g. the common Brinell test is reported in terms of a Brinell Hardness Number (BHN) that is the compressive strength of the metal tested in kilograms per square millimeter. The numbers can be converted to pounds per square inch if desired. Such values are not representative of tensile strength except in those cases where a ductile material has about the same strength under both types of stress. Hardness tests give no measure of toughness, which makes an important contribution to wear resistance in some circumstances. Hardness also has a poor correlation with resistance to grinding abrasion.

Abrasive wear results from the failure of a material under stress, but the stress patterns imposed in service are so varied and complex that test information in addition to hardness- is desirable. Of the three designated types of abrasion erosion is expected to be present in grinding mills, but it is believed that it makes only a minor contribution to the total wear; gouging abrasion is not considered applicable since it is the type observed in large crushers and in dipper teeth; and grinding abrasion is not only recognizable as present but the matching laboratory test has a demonstrable relation to grinding mill service.

Grinding or high stress abrasion typically results when small mineral particles are caught under pressure between two metal faces. Even with low nominal loads on the metal portion of this sandwich the unit stresses in the abrasive, and consequently on its metallic contact areas, may be very high. These stresses crack or crush the abrasive grains. The broken edges are sharp and can scratch effectively. Moreover, the concentrated stress on the metallic face can disrupt the metal or fragment some of its microconstituents and deterioration can occur from scratching, from local plastic flow and from micro- cracking. The presence of high stress abrasion can be deduced from observation of the metal sandwich described and from the fact that an abrasive is ground or crushed on a small scale.

At the very tough extreme, where austenitic manganese steel is preeminent, the area under a tensile stress-strain curve (or the more convenient merit number) can be used for comparative ranking. This area is an indication of the energy required to deform the material. However, complete stress-strain curves are not usually available; the extensometer that shows strain is generally removed after the yield strength is passed, since it has only a limited range of measurement, and thus only the early part of the curve is obtained.

A rough approximation of the area under the stress-strain curve can be obtained by multiplying the tensile strength (in psi) by the elongation at fracture. This is the merit number, which can be conveniently applied to any alloy for which tensile data are available. If due allowance is made for its approximate nature, it is considered a valid measure of toughness for materials where fracture is not complicated by cleavage. It can be applied even to the brittle cast irons, but to do so requires carefully machine ground specimens, almost perfect axial alignment in the tension test, and the use of high precision strain gages, e.g. of the electrical resistance type. Consequently such data for the hard irons are rare.

Compression tests can also show strength and capacity for plastic flow before fracture occurs. They are seldom reported for steels, probably because tension tests are more convenient. For quite ductile materials the values in tension and compression may be quite similar. For brittle alloys like the cast irons they can be vastly different.

Actually we know that both balls and liners of Ni-Hard will spall and fracture in some mills. Discounting those failures that result from poor fit or bolting practice that produces excessive tensile stress on the back side of a poorly supported liner, it can be accepted that Ni-Hard is borderline in toughness for mill liners.

As a result of ball action in a mill,work hardening and high residual compressive stresses occur at the metallic surfaces involved. This implies that the yield strengths have been exceeded, as these phenomena are associated with plastic flow. One aspect of brittleness is the lack of ability to plastically deform under stress. This may be general in a hard metal, the characteristic of a particular phase in an alloy (e.g. the brittle iron carbide in cast iron), or it may be a directional property, perhaps affected by temperature. The crystallographic property of cleavage in some minerals, well known to mining engineers, also occurs in some otherwise ductile metals, especially below a transition temperature. Notched bar impact tests tend to show up this kind of brittleness much better than do tension tests. Even ductile materials may show brittle failure with triaxial stresses, which tend to be produced at the root of a notch.

Austenitic manganese steel, which is also called Hadfields manganese steel after its inventor, is an extremely tough non-magnetic alloy in which the usual hardening transformation has been suppressed by a combination of high manganese content and rapid cooling from a high temperature. It is characterized by high strength, high ductility and excellent wear resistance. In the form of castings or of rolled shapes it serves many industrial requirements economically and has built up an enviable record as the outstanding material.for resisting severe service that combines abrasion and heavy impact. It provides the tough extreme of the alloys available for mill liner service.

Some hundreds of other experimental manganese steels have been studied. From these a few have reached commercial production but not general acceptance. Since the full measure of toughness available is almost never needed in mill liners, there is little incentive to choose from among the modified grades unless better abrasion resistance can be demonstrated in grinding mill service.

Some years ago manganese steel liners were more popular than they are now. Originally adopted because of the excellent wear resistance of this steel in other applications, experience revealed that other materials would outwear it in grinding mills. There was reluctance to change until the questions about adequate toughness in the alternate materials could be answered. It is now known that in some mills even brittle cast irons can stand up; in others the irons will chip or fracture under ball impact while some of the steels that are hardened by heat treatment are tough enough. In a few cases manganese steel is still retained because its toughness (which is far beyond that of the hardened mill liner steels) is considered necessary.

If the questionable concept that work hardening contributes to the abrasion resistance of manganese steel is accepted, it is logical to modify this family of alloys to achieve more rapid work hardening. This can be done, but in the field of grinding abrasion the results are likely to be disappointing. The two 8% Mn steels in Table 8 work-harden considerably faster than the standard grade; indeed they become somewhat magnetic from the deformation that causes the work-hardening, suggesting that the martensitic reaction, often postulated but not proven for the standard 13% Mn grade, is actually occurring. In this case the abrasion resistance is clearly inferior to that of the more stable 13% Mn type. The two 8% Mn steels also lack toughness.

Lowering of either carbon or manganese tends to degrade the properties for which the 13% manganese steels are valued. However, it is possible to counteract this degradation by adding other elements. Such compensation is practiced, chiefly in the field of welding electrodes. Most of these invoke this pattern.

The earliest cast irons used in grinding mill service were simple pearlitic white irons; that is, the composition was adjusted or the castings were chilled in manufacture to produce a mixture of cementite (iron carbide) and pearlite (the lamellar aggregate of cementite and ferrite that is a common constituent of slowly cooled medium and high carbon steels). Slowly solidified cast iron that is high in silicon will have much of its carbon appear as graphite flakes; these are considered undesirable for abrasion resistance and are suppressed by control of the silicon, perhaps by additions of chromium and by means of chills in the mold.

White (graphite free) cast iron has good resistance to low-stress scratching abrasion or erosion, but it has been disappointing in grinding mills. The Abex test provides abrasion factors that are generally between 0.90 and 1.00, indicating that it is very little better for resisting grinding abrasion than soft mild steel. It required some years of experience for this to become well recognized in service, but now a simple white cast iron is seldom considered for mill liners.

Irons alloyed to produce martensite instead of pearlite in the microstructure are a different matter. Following the introduction of Ni-Hard (U.S. Patent 1,988,911 issued in 1935) it became evident that this type (Table 12) had better abrasion resistance than the ordinary white cast iron under a variety of conditions. Wot only for low-stress abrasion but also under the high stress conditions of ball mills it could show superiority. With its excellent potential for resisting wear the matter of toughness became, crucial. Its performance in grinding mills would depend on whether it chipped, thus adding a second deterioration mechanism to that of abrasive wear, and on whether there would be gross breakage under mill impact conditions. Pear of the latter retarded its acceptance as a liner material. It was accepted first for balls.

Promising alloys have been previously introduced into mill liner service only to find that for some reason they cannot compete with existing materials. Unless they cost too much their deficiency has usually been in either toughness or abrasion resistance. The 19% chromium iron aimed at the apex of one of the computer parabolas is now in the field testing stage. To reach this point has required considerable pilot plant and production effort, as processing details and quality controls had to be worked out on a full scale basis. Also, a full set of liner castings is necessarily expensive and thus the initial tests had to be introduced on a guaranteed performance basis. The field testing is still in progress but results have been favorable. Two tests can be reported at this point.

One test was made in a 12 2 diameter x 14 long Nordberg rod mill with medium height overflow discharge and Noranda type shell liners. The grinding media are 4 3/8 inch diameter rods of 1090 steel at about 269 311 Brinell hardness. Mill speed is 13.3 rpm, which is about 59% of the theoretical critical speed. The feed is 1 inch size and the product is about inch; the pulp density at discharge is about 75%. The production rate is 110 long tons per hour or 3000 short tons per day. The ore being ground is taconite. The ore mineral is magnetite, which itself is quite hard, but the abrasiveness of the ore is attributed largely to quartz and hard silicates that are so well interlocked that the material is very tough, with an average compressive strength of around 55,000 psi.

The pepper mill gives you control over six grinding levels that lets you choose the texture you prefer for your pepper. From coarse to finer textures, you can easily adjust the output of your table mill.

This French-made pepper mill offers a unique design. It has a body framework that closely imitates the pawn/rook chess piece. The product is available in chocolate color as a 5-inch-high mill, although other variations are available from the producers.

The Peugeot Uselect pepper mill features six different predefined levels that enable you to adjust the coarseness of your grind. The mill is extremely easy to use, a quick twist on the ring at the base is used to preselect the grind size you want. With clockwise direction leading to finer grind while a turn on the opposite gives you a coarser grind.

The grinding mechanism has two different stages, tagged as the burr-style system. The process involves a helix-shaped groove guiding individual peppercorns through double row teeth that grind it into a consistent size, releasing fresh, untainted flavor of spice.

The mill comes in several different colors, depending on what you need. It is a versatile tool that can just as easily grind coarse salt. In fact, this is the recommended means of cleaning the internal grinding system by the manufacturer occasionally using it to grind coarse salt.

The ratchet handle is very ergonomically designed and makes the product a fantastic choice for users who dont want the trouble of twisting or turning rings on small containers.

The grinder is made from ceramic, which delivers the needed toughness and strength needed to make fine particles of your peppercorns. The material is also resistant to corrosion that would otherwise be a problem for metallic grinders. In addition, ceramic does not absorb the flavors of your pepper; hence, the same grinder can be used for different spices.

how to choose stone grinding machinery

Before buying a stone grinding machine, consumers must decide what to grinding with this stone mill. Stone mills are divided into wet grinder mills, flour and powder mills, nut butter mills and special shaped stone mills. Each stone mill has different uses. Many customers expect a stone mill to grind all materials, which is impossible. For example, grinding soy milk and sesame paste are different, you can not use the same stone

Choose a long history stone mill brand. The long history shows that the stone mill manufacturers have reliable quality and good after-sales service. And has its own design and development team, professional technicians, and has a deep knowledge of the stone grinding process. Buying stone mills has a very good guarantee.

how to choose a 325 mesh calcium carbonate grinding mill?

325 mesh calcium carbonate calcium carbonate powder is widely used. Which calcium carbonate grinding mills are suitable for producing 325 mesh calcium carbonate powder? Below we will try to find the answer for you.The models mainly involved in calcium carbonate grinding mill is YGM Raymond mill and HGM micro powder grinding mill.

Kindly noted, the calcium carbonate powder we mentioned is ground calcium carbonate powder.Aboutprecipitated calcium carbonate(light calcium carbonate powder,PCC) we will analyze in detail in subsequent articles.

Ground calcium carbonate powderalso namedheavy calcium carbonate powder,AbbreviationGCC.It is made of high-quality limestone and processed into a white powder by a lime mill. Its main component is CaCO3.

HGM micro powder grinding mill is the new type mining equipment for making micro powders, fine powderswhich is widely applied in the industries of metallurgy, mining, chemistry, cement, construction, refractory materials, ceramics, and so on.The purpose of the micro powder grinding millis for super-fine grinding materials with hardness less than 9 in Moh's scale and humidity less than 6 percent such as kaolin, limestone, calcite, marble, talcum, barite, gypsum, dolomite, bentonite mud, mica, pyrophyllite, sepiolite, carbon black, diatomite, graphite, alunite, fluorite, potassium feldspar, phosphorite, pigment, up to 200 kinds.

Calcium Carbonate Powder Making Machine Production line: consists of hammer crusher, bucket elevator, storage hopper, vibrating feeder, main unit, inverter classifier, cyclone collector, pulse deduster system, high pressure positive blower, air compressors and electrical control systems.

When the grinding mill is at work, all the grinding rollers are rolling in the ring, and the materials are driven to the edge of the turnplate by the centrifugal force and fall down into the grinding chambers where the materials are repeatedly pressed, crushed and grinded by the rollers.

The high-pressure air blower constantly inhales air within the grinding mill and, in turn, the airflow with crushed materials are brought to the classifier whose high-speed impeller will screen the airflow: the unqualified particle size will fall and return to the mill for being reground while the qualified particle size mixed with air will go into the cyclone powder collector. Most of the qualified powders will fall and exit from the discharging valve at the bottom; a small proportion of the fine powders, with airflow, moves to the dust cleaner, and clings to the surface of the filter bags. At the same time, the fine powders clinging to the surface fall down by the sudden vibration of the filter bags, which is caused by the instantly ejected high-pressure gas controlled by the pulse valve. The materials from the above two lots are sent by the conveyor at the bottom to get finished powders packed. In addition, filtered clean air will be emitted from the air outlet of muffler in the end.

According above information we can see, if you only want to produce 325 mesh calcaium cabonate powder and the application industry does not require high quality powder, Raymond mill is cheaper and is a better choice. But if your downstream industry has high requirements for powder quality, you also have the need to produce higher fineness powder, and your country is environmentally demanding, and you don't want noise, HGM micro powder grinding mill will be the best choice.

how to choose a pepper mill - chowhound

When looking for a new a pepper mill, Chowhounds suggest you ask these questions: Is it easy to load with peppercorns? Can you set the fineness of the grind? Will it produce that grind consistently? Does it have good ergonomics?

A mill with a hand crank is better than one with a rotating knob at the top, kaleokahu says, especially when you need to grind a large amount of pepper. Just make sure the hand crank is long enough to give enough leverage, tim irvine says.

As for brands, several Chowhounds love their Atlas mills, which are easy to load and use and last a long time. Other favorite brands include Peugeot and Cole & Mason. John E. likes his Vic Firth mill, which has a locking mechanism that keeps the grind consistent. And mcf loves the way a Vic Firth grinds large amounts of pepper. The only drawback: Its a bit awkward to fill. Meanwhile, jmcarthur8 is happy with a PepperMate purchased in the 70s or 80s; it does a great coarse grind. Five grinds yield 1/8 teaspoon of pepperif you buy a quality grinder and measure the grinds-per-teaspoon ratio once, says kaleokahu, you never have to measure again!

how to choose a liner and ball for a ball mill - eb castworld

Leading supplier of high alloy castings and forgings. There are 4 companies with sales of more than 100 million yuan, across the 4 major areas of wear resistance, heat resistance, corrosion resistance, and machinery

There is no doubt that the liner and the grinding ball are in a cooperative relationship. They and the material together form a three-body abrasive wear. But whats so good? It should be said that borrowing the concept of basic hole system or basic shaft system in mechanical design is the best understanding. As far as the ball mill is concerned, the influence of the lining plate on production is much greater than that of the grinding ball, so it should be made of substrates. Therefore, in the selection of the liner and the grinding ball, the first thing to decide is the liner. The service life of the liner must be more than two overhaul periods, and as far as possible, no maintenance is required. Priority is given to those liners with good reliability and high degree of wear resistance. For example: combined self-fixing high-chromium cast iron liners, the service life of coal mills in power plants can reach 20 years, the service life of cement mills is 10 years, and almost no maintenance is required.

The hardness of the liner and the grinding ball should be above HRC50. This is mainly because the hardness of the hard phase in the abrasive is 6 ~ 7 on the Mohs scale. It is estimated to be close to HRC60. In theory, the hardness of the grinding medium is greater than or equal to eight percent of the hardness of the abrasive. Ten has the ideal anti-wear effect.

The grinding ball is easy to choose after the lining board is decided. As long as the service life of the lining board guarantees two overhaul periods, it should be advocated that the best wear resistance of the grinding ball is preferred. If the liner and the grinding ball can be changed for 10 years, it is of course ideal. One principle: reduce costs, reduce labor intensity, and increase the operating rate of ball mills.

Under the premise of substrate-made, grinding balls are allowed to have a hardness higher than HRC by 3 to 5 HRC. This is for high-manganese steel liners that should be eliminated, and it is fundamentally different from the popular concept.
