conveyors types in grinding cementpanies

belt conveyor

Belt conveyors used to transport minerals are to be found all around the world in a large number of surface and underground mining operations. The idea of using the conveyor belt is not new, indeed, the first bell conveyors were introduced at the end of the nineteenth century; the basic principles of operation have not changed. However, over the years the capacity rating of belt systems and the length over which material can be transported have increased very considerably, together with the power inputs, the size of components, and the degree of sophistication.

The type of belt conveyors are used to transport various materials over relatively short distances both horizontally and on an incline where the angle of the latter does not exceed 21 to 23 in exceptional cases. Thematerial can be of almost anysize and either dry or wet, butin the latter case the moisture content must be known and taken into consideration when figuring such installations. Usually the belt is supported at regular intervals by troughing rollers on the carrying side, while a number of flat rollers are needed for the return side.

Conveyor belting designed for the particular service is usually rubber covered, the upper or wearing side in many instances being further reinforced by an extra thickness of tread rubber which may or may not extend to the outside edge of the belt, while the under or pulley side has only athin coat to protect the duck. Duck for conveyor belting ordinarily weighs 28 to 42 ounces and the plys from 3 to 8 depending on the factors of length of conveyor, width of belt, size of head and tail pulleys and the weight and character of material to be handled.

A well designed concentratorconveyor system will make this ore transportation problem seem very easy. But, like anything mechanical, there are a few guide lines that should be followed to maintain the conveyor systems efficiency. So in the following chapter we will discuss different conveyors. Their components and some of the operating skills required to be efficient in their control.

The advantages of a conveyor are that it uses a lower energy output to revolve the flexible belt, it requires a minimum of maintenance, has a low initial cost, and it delivers the ore at a constant flow. This last is a requirement of some of the processes involved in mineral recovery.

The BELT. This is a flexible surface, usually constructed in altering layers of rubber and cord. The cord may be of different material and is included in the design to prevent the belt from stretching and or breaking.

Like everything else, each mine has its own problems when dealing with ore handling characteristics. Sometimes the ore will be very wet and sticky. This may mean using POWER BRUSHES and BEATER ROLLERS to keep the dirt knocked off of the belt face. Dust may be the problem, whatever it is, there has been equipment designed to deal with it.

Instead of describing individual conveyors as I have been, I think we should graduate to systems that use two or more conveyors in a CIRCUIT. In modern mills it is not unusual to find two conveyors feeding onto a single conveyor. It is also normal to find one piece of equipment feeding one or two other pieces of equipment. When this happens the conveying system that is required to deliver the ore in a steady controlled fashion can be quite complicated.

To have the equipment as versatile as possible, you must be able to adjust the rate of feed. If you remember earlier when we were discussing feeders I stated that you can control tonnage by either increasing or decreasing the volume of the ore or the speed that it is moving. When you are dealing with conveyors you pretty well have to control the speed. This will be done by changing the speed of the electric motor driving the belt or by changing the gear ratio in a GEAR REDUCER. The simplest form of gear reducer is a small gear driving a large gear. For every revolution the larger gear makes the little one has to travel farther to keep up. If the ratio is 10:1

The belt conveyors used to transport the ore in the crushing plant commonly run at 100 to 200 ft. per min. and vary in width from 16 to 36 in. according to the tonnage to be handled. Their capacities and power requirements are given in Table 4. The belt should not be run at a greater inclination than 22, as the ore tends to roll backwards on a steeper slope.

The above figures are based on normal design for heavy-duty conveyors. They are calculated for a belt speed of 100 ft. per min.; for faster travel the capacity and power figures must be increased in direct proportion to the belt speed. Usual practice is to run the belt at about 200 ft. per min., in which case the figures in the table should be doubled.The power requirements are given for a 100-ft. length of belt; for longer or shorter lengths the figures must be increased or decreased respectively in direct proportion to the belt length in feet measured from the centre of the head to the centre of the tail pulley. The capacity figures remain constant whatever the length of the conveyordepends on the distance between the bottom edges of the two jaws at the end of the backward stroke when they are open to their widest extent; this distance is determined to about half an inch by the size of toggle plates used, any finer adjustment being made by placing shims (242) behind the toggle block (240). In some makes of crusher, however, the last adjustment is made by means of a taper wedge which is situated behind the toggle block and can be moved up or down by turning the nut on the bolt that supports it. The faces of both jaws are protected from wear by manganese steel liners.

It is common practice, and certainly good business as all of us know, to take care of plant operating equipment. Machinery of any type requires periodic inspection and planned maintenance. With this thought in mind a plant operator should at the end of every shutdown period make regular belt inspections and plan for later appropriate care and maintenance.

The points mentioned below are understood well by all of us but are sometimes forgotten because belt conveyors are comparatively easy to operate. Maintenance of any conveyor belt is dependent upon the fundamental characteristics of the two component partscover and carcass.

The interior cotton fabric, cord, steel cable, or synthetic fibre plies supply the main structural strength of the belt. They do the work of supporting and pulling the load, whereas the rubber covers provide resistance to corrosion, abrasion and impact. The load-carrying carcass plies are subject to many hazards such as abrasion, impact and corrosion. The rubber with which they are covered and impregnated is many times more resistant to these damaging conditions. Rubber can stand up well against abrasive action and shock impact as long as the force involved does not distort the rubber beyond its elastic limit. When the rubber cushion cover of a belt is distorted beyond its capacity to yield, the surface is cut or broken and the protective cushion torn away, leaving the interior carcass exposed to damage. Injury and damage are of far greater importance in determining how long a belt will last than the number of tons of material carried.

Is the load on a particular conveyor belt dropping from a height greater than necessary onto the belt? (a) Install an inexpensive short feeder belt to take the greatest abuse, (b) Use a pad belt at the loading point for severe impact loading conditions. (c) Several types of shock impact rubber-covered carrying idlers may be used at the loading point, (d) A screen or grid that permits fine material to be placed on the belt first and act as a cushion for larger lumps is standard practice for good loading, (e) For some types of loading the middle horizontal carrying idlers have been removed to eliminate hammer and anvil action.

It is expected that troughing idlers, return idlers, as well as drive terminal, snub or takeup pulleys, be maintained with a clean surface for belt alignment and long life, (a) Terminal Pulleys. Granted that head and tail pulleys are of proper diameter for belt width and thickness the life of a conveyor belt is often endangered by slippage on pulleys and caused by lack of cleaning. Accumulation of such material may cause the belt to run to one side, seriously damaging the belt edge. Material may cling to the belt beyond the drive snub pulley location and then build up on return or takeup pulleys to again cause serious belt misalignment and damage, (b) High tension snub pulleys operating against the dirty side of the belt may be lagged with a -in. thick soft rubber lagging with smooth surface. The movement of soft rubber surface tends to brush off material buildup on the belt, (c) A layer of 3/8-in. soft rubber may be vulcanized or lagged to drive pulleys. Lateral or herring-bone grooving of the rubber pulley surface provides not only a surface movement for cleaning, but also a higher coefficient of friction for wet drive conditions, (d) The use of all-rubber wiper blades is usually most effective in conjunction with water spray.

Considerable attention should be given to return idler cleaning inasmuch as these idlers all contact the belt carrying side. As stated before, buildup on return idlers may cause the belt to run off and damage belt edge. Several means have been used to clean return idlers, (a) Carrying idlers. (1) In some conveyor installations there is a tendency for moisture to condense on idlers and combined with ore forms a coating on the moving parts of the idlers. Corrosion of metal parts may result, with an eventual frozen idler to cause misalignment.

Conveyor belts are best repaired by electrically-heated vulcanizers of the appropriate size to accommodate certain width belts. Vulcanized repairs can be made by any good plant maintenance man after a few hours of instruction. Repairs usually require replacement of broken carcass plies and/or missing cover patches with new unvulcanized stock. Belt splices are made in much the same manner as repairs using a conventional step-splice design

different types of concrete equipment for construction - part 1

With good quality concrete construction equipment, a construction company can get quality construction work done in a lesser amount of time. It can, therefore, cut down on its labor costs and increase profits by giving the quality construction services to its clients in a faster way. With advancement in technologies, today a number of concrete construction equipment are available in the market. For every construction site, there exists a diverse range of construction machinery for faster, easier and safer constructions. Today, several manufacturers are supplying high-quality concrete construction equipment. It is pivotal to choose the equipment that renders more feasibility for your construction project.

A concrete batching plant is a machine in which ingredients of concrete are mixed and blended homogeneously to obtain concrete of desired strength and quality. Concrete batching plants can be classified as stationary concrete batching plants and mobile concrete batching plants, based on the location of the plant.

Mobile batching plants can be used wet or dry and has a wide array of configurations and production types including Ready Mix, Precast & Prestressed, Central Mix, and RCC. Mobile Concrete Batching plant models are now fully automatic. The towing arrangement in the plant facilitates it to be towed by tractor or equivalent power. The new plant models comprise adequate capacity gravel & sand hoppers, weighing conveyor suspended on electronic load cells, reversible drum type mixer unit, cement bin with screw conveyor, rubber belt type charging conveyor, cement batcher, PLC based control panel. Modern mobile plants consisting of portable shaft mixers are designed to be moveable and thus are installed on a towable chassis with wheels for maximum mobility and quick setup. The compact design boosts the production capacity and fits in thin plot sizes. The new concrete batching plants at your job site, the plant can be fully erected and operational in less than four hours. All components are on board and the entire plant is pre-wired and plumbed for air and water. All plants tested at our factory to ensure trouble-free start-up and operation.

Stationary concrete batching has seen an upsurging rise in demand and manufacturers are modifying new models based on the customer need. The new models are furnished mainly with twin shaft mixers for maximised capacity, the plants are also available with Planetary mixers and batch sizes could be modified. The Stationary Plants are available in various capacities ranging from 30 m3 to 240 m3 per hour of compacted concrete output. In the current Stationary concrete plants, the aggregates are stored in horizontal bins. The gathering conveyor belt runs below the bins where the weighing of aggregates takes place and the aggregates are then discharged onto the charging conveyor. Pneumatically operated gates are provided for discharge of the aggregate on to the gathering conveyor. The material is all weighed accurately and transferred to the twin shaft mixer through a slinger conveyor. The new batching plants also come with the Skip Hoist and Belt arrangement option for mixer loading and a modular PLC-based control system with real-time SCADA for control and data management, The news design models can adopt Ice dosing, Microsilica dosing and some special additives very easily. An Admixture Dosing Unit and a standard Cement Screw Conveyor are also a part of the standard offering. Special plant designs are available for dam construction and precast manufacturers.

Concrete mixers can be divided into two broad categories Batch Mixer and Continuous Mixer. Continuous mixers are used in massive construction sites such as, for construction of dams, bridges, etc., which involves the use of large masses of concrete and also requires continuous flow of concrete. Batch mixer is one of the most common types of mixer and it is widely used to mix the concrete ingredients. It consists of a revolving drum with blades or baffles fitted within it. In this type of mixer, all the materials of the desired proportion are mixed and fed into the hopper of the revolving drum.

Modern batch mixers come with a ribbon or paddle agitator. The mix is held in constant suspension providing for excellent uniform mix of the product. Paddle assemblies mix using a tumbling motion and have less product shearing during the process. Batch mixers are ideal for a wide variety of applications, especially where production quantities are small, strict control of mix composition is required, formulations change regularly or batch traceability is necessary.

Continuous mixers provide a more economical alternation for big capacity to meet process requirements. The modern continuous mixer can handle up to 5 different materials at one time, mixing powders with another powder, powder with a liquid or several liquids together to create a homogeneous product free of any agglomerates or lumps. he weighing, loading, mixing and discharge steps take place simultaneously and continuously in a continuous mixing system. This allows for lower mixing times, consistent mixing performance (no batch-to-batch variation), decreased energy usage and automatic control. All blenders, mixers and agitators can now be custom built to efficiently and cost-effectively meet each application requirement.

There are mainly two types of concrete pumps, line pumps and boom concrete pumps. The line pump is mounted on a truck and placed on a trailer. Line pumps normally pump concrete at lower volumes than boom pumps and are used for smaller volume concrete placing applications such as swimming pools, sidewalks, and single-family home concrete slabs and most ground slabs. The second type is boom concrete pumps. These pumps are attached to a truck and use a remote-controlled articulating robotic arm. They are mostly used on big construction sites and pump at very high volumes.

With the addition of equipment and technology under these two divisions several subdivision categories of concrete pumps have developed namely, mobile stationary pump, Truck Mounted Static Pump, Truck Mixer Concrete Pump and many more.

Modern stationary pumps come with the appropriate delivery line and the stationary placing boom system. The new updated models come with a high-pressure pump that caters to concrete pumping to 80~100m building heights. The models are equipped with the latest S-valve technology and with highly wear-resistant steel components.

Modern truck-mounted concrete pumps cover a range of horizontal and vertical reaches with placing booms between 20 and 63m in length. The new product range covers numerous applications starting with the small, versatile concrete pump and ending with the concrete pump that has the highest reach and best maneuverability. The machines can take high delivery pressures up to 130 bars for delivery outputs of up to 200m/h. The new series machines come with mounted on a truck chassis of your choice. It is also possible to customise your setup to include storage for all your pipework and other accessories so youve always got everything you need in the one mobile package.

Truck mixer concrete pumps combine a truck mixer, a concrete pump and a placing boom all in one package are ideal for supplying especially small construction sites with concrete in a quick, simple and cost-efficient way. Truck-mixer concrete pumps are ideal for supplying especially small construction sites with concrete in a simple and cost-efficient way. With the 1000 mm long-stroke pumping unit, these machines need fewer strokes with the result of reduced wear and lower fuel consumption. Also, these machines can easily reach delivery rates of more than 60 m/h.

With the production needs, especially the rapid development, the use of the concrete equipment construction industry has changed. Nowadays, manufacturers of concrete construction equipment incorporate the latest technology to eliminate raw material storage space and raw material wastage. Modern concrete equipment adheres to maximise technology for a better result.

Koenig Pump is a screw type pump used as a feeding device to Medium Phase Pneumatic Conveying of pulverized materials such as Cement, Raw meal, Coal, Pet-coke, Lignite, Soda Ash and many other powdery materials which are less abrasive and good fluidization properties. This is a continuous Conveying and hence most of the coal or pet-coke firing application, screw pumps are predominantly used.

Material received in the Inlet hopper pushed through specially made variable pitch screw which compacts the material when advances towards the discharge position. This compacted material acts as the material sealing to feed into the Conveying line. To protect the bearings from material accumulation, Air purge sealings are used at both Drive and Non-Drive bearings.

The Koenig Airlift for silo charging, kiln feed application facilitates a dust-free vertical transport. It does not require any maintenance as there are no mechanical moving parts in the conveying stream which need to be maintained.

A rotary blower supplying the conveying air does not require much maintenance either. Parts of an airlift system are: The cylindrical air-lift body made from steel with fluidizing bottom, the vertical nozzle and conveying pipe, a cyclone separator (when not charging directly a hopper or a small silo). A rotary blower or a group of blowers supply the necessary oil-free conveying air. There will be a dedicated Rotary blower for fluidization.

This type of silos are the most efficient blending silos as we can increase the No. of extraction to meet the expected blending requirement. To avoid segregation of coarse particles, silo is fed through multiple points sequentially.

Koenig also offers Flat Bottom blending silos by dividing the silo internal aeration with multiple segments. We have three types of Flat Bottom Blending silos with 24 Segments, 36 Segments and 42 Segments respectively. No. of segments determines the blending efficiency.

Flat Bottom Blending silos can be constructed with limited civil construction capabilities. The complete inside surface of the bottom slab is mounted with Koenig Aeration pads and the withdrawal from Silocenter. To reduce the load on extraction gates and avoid possible bridge formation, a steel cone is mounted at the extraction location at center. The main advantage of Flat Bottom Blending Silo is less number of extraction gates and thereby less maintenance.

Koenig offers 2 types of Blending cum Storage and extraction system. Our Blending silos are continuous feed and gravity blending type. The blending is achieved through sequential aeration and extraction methods which stimulates the variable material velocity inside the silo and thus blending / mixing happens by gravity. This is no energy spend for blending and blowers are used only to aerate the material for extraction and NOT for blending.

Koenig offers 3 types of Storage Silos and extraction system. Aeration air is supplied through a set of dedicated Positive Displacement Blowers and the Standard accessories include Over / Under pressure relief valve, man hole doors.

Koenig offer steel silos for smaller capacity up to 1000 MT with central outlet and the conical portion is mounted with Koenig Aeration pads. No of Aeration pads depends upon the steel silo diameter and withdrawal capacity.

Koenig offers also Flat Bottom Silos where the civil construction capabilities are very limited. The complete inside surface of the bottom slab is mounted with Koenig Aeration pads and the withdrawal from Silocenter. The main advantage of Flat bottom silo is less number of extraction gates and thereby less maintenance.

Koenig offers wide range of complete Bin Weighing and Dozing system to meet the accuracy requirement up to 1%on Full Scale. A typical Koenig Bin Weight Indicatorsystem features several load cells connected to a special purpose micro controller. The micro controller provides both analog and digital interfacing options to other systems.

We supply the perfectly matched components like Load cells, Fabricated Bins, Aeration and Extraction system, Metering Flow Control valve and other necessary mechanical components. The weight of the contents of silos, bins, mixers or reactors can be determined with the help of these components.

A belt feeder can be used to transport and meter a wide variety of bulk materials. When the metering precision expectation is around 5%, the belt feeder can be designed to provide a desired feed rate downstream based on volume for every rotation of the head pulley.

Koenig Apron feeders are used to extract or feed large, lumpy, abrasive and heavy ores under severe impact conditions - including wet, sticky or frozen operations. A robust, heavy duty design provides minimal downtime and many years of service life.

Koenig offer a variety of bucket elevator designs and sizes to handle materials ranging from dry dusty powders such as fly ash, to heavy materials such as iron ore pellets. Bucket elevators can be ordered in several configurations, including centrifugal belt, centrifugal chain, continuous belt, continuous single chain and continuous double chain.

Centrifugal bucket elevators are chosen when there is a need to move large amounts of material quickly. Instead of direct loading, buckets serve as the loading apparatus, scooping material up from the boot or inlet section. For this reason, durable buckets should be selected with this design. Centrifugal force at the head pulley throws material from the buckets into the discharge chute.

Material is fed into the buckets from an inlet chute. Buckets are closely spaced on the belt or chain to allow the material to flow over the backside of the preceding bucket, whose extended sides form a chute to guide the material into the discharge spout.

Bucket elevators can handle a variety of materials, and therefore are used in many different industries and applications, though generally, they are not suited for wet, sticky materials, or materials that are stringy or tend to mat or agglomerate.

Koenig Arc Valve is Air Tight Shut-Off valve with spherical disc, operated through Pneumatic Actuator and used in the Material lines namely Material Inlet, Material Discharge and Vent line in Pressure Tank systems.

Koenig Arc Valve has a sturdy Spherical Disc which can cut through a full material flow without any limitations. The spherical Disc is coated with high-grade wear protection on which the inflatable Sealing gasket is mounted thus ensures more reliable, long service.

Koenig Flow control valves have basic type with different actuators have in common, the extremely high accuracy of a controlled flow of pulverized bulk goods with reproducible results. We have three actuations namely Manual, Pneumatic (On-off), Motorized (Regulating / Dozing).

Koenig Flow control valves, a complete disassembly becomes unnecessary. Maintenance can be carried out while the valve remains built-in. After having taken off one of the side plates the roller can be taken out. The gasket is then accessible and can be replaced if required. Re-assembly is done in reverse order.

Koenig Rotary Valves are designed to suit the application and we have 3 variants namely Light Duty, Medium Duty and Heavy Duty. Koenig Rotary Valves are manufactured with a square and circular flange to reduce installation / building height. We have wide range of Rotary valves and supply up to 300 m3/hr.

Koenig-LD Rotary Valve is specially designed for use in combination with dust filters, cyclones andproduct separators. These valves are suitable for use in simple and light industrial applications whereby the valve primarily functions as an airlock.

Koenig-MD Rotary Valves have been specially designed to offer a suitable and economic solution for standard applications with a limited pressure differential up to 0.5 bar. These valves are used extracting/dosing material, mounted below silos/hoppers for abrasive or mildly cohesive products.

Koenig-HD rotary valves are employed in the conveying and dosing of almost any kind of product in the most demanding applications. These valves are eminently suitable for handling powdered and granulated materials in pneumatic conveying systems up to a pressure differential of 1.5 bar.

Occasionally parts of the agglomerated cement move with fresh cement which flows smoothly towards the discharge spout. At this bottleneck, these lumps plug up the discharge aperture causing discharge trouble. The cement flow is reduced or comes to a full stop.

The SG Slide Gate handles dry material in gravity flow applications where positive material shut-off and dust tight sealing is required. This slide gate is available in a wide variety of configurations with square, rectangular sizes and customer specific hole patterns.

The diverters access panel allows for quicker entry to the interior of the diverter for inspecting and cleaning the valve. The heavy-duty abrasion resistant bucket is also removable through this access panel for service.

Clamshell gates are suited for the unrestricted bulk discharge of bulk materials out of silos and bunkers. In an open position the clams are situated outside the area of material flow thus improving the life cycle of the clamshell due to reduced wear.

The clamshell gate is designed so that most material tends not to push the gates open under normal operating conditions resulting in a fail safe gate should air pressure be lost to the pneumatic cylinder. Cylinder mounted limit switches can be fitted as optional extras.

The RG Rod Gate used as Isolation / Regulating the material flow from Silos, Bins feeding to other material handling equipment like Apron feeder, Belt feeder. This rod gate is available in a wide variety of configurations with square, rectangular sizes and customer specific hole patterns.

Koenig Pneumatic Flap Valve are generously sized with steeper inlet angles than other valves available. This bigger opening allows better gravity flow with less bridging resulting in more efficient operation. The valves are supplied with wear resistant' chutes and flaps as standard.

The Pneumatic operation can be achieved either through Kinetrol Actuator or pneumatic cylinder to get the desired performance. By fitting a timer device, the valve can be controlled exactly to your required timing cycle. This can result in significant savings in energy and air.

industrial coolant filtration system and filters for grinding

Grinding process is used to generate better surface finish on components. Alongwith the removal of metal particle, the grinding wheel is also consumed. If proper filtration is not provided these particles escape the filtration system and generate scratch marks on the surface deteriorating the Ra and Rz values. The particles also clog the grinding wheel, which needs to re-dressed frequently. This increases the consumption of the grinding wheel.

A CFS for Grinding process is sized based on wheel grit size, viscosity of fluid and material of component. As the viscosity increases or the grit size becomes finer, the flow velocity through filter media has to be reduced to achieve desired results.

A CFS for grinding is similar to indivisual filtration system but at a much larger scale. Dirty fluid alongwith grinding muck falls into the vacuum filter. Dirt cake is generated on the filter media ( check the actual working ). Clean fluid is directly pumped back to the machines.

Multiple part of a 2 wheeler are made of aluminum die cast. Components are machines, drilled and bored to achieve finished stage. This generates large quantum of chips. Considering the high production requirements multiple machines are working at the same time.

This generates a large quantum of chips. Chips were separated in individual tanks and fluid pumped back to machine. Chips had to be cleaned manually from each tank. This caused significant machine downtime. Customer wanted to reduce this machine down time and if possible completely eliminate it.

Properties of coolant like pH, concentration etc. had to be maintained at each machine. This caused irregularities and required lot of manpower. Due to the space limitation available for individual tanks, filtration level achieved was compromised resulting improper filtration reducing the coolant life and frequent breakdown of machines.

Veeraja proposed a centralized filtration system with large conveyors and mesh drum filters. A layout was prepared with the process planners from Bajaj Auto ltd. Civil trenches were dug in existing machine shop. Advance in civil engineering has made it possible to dig inside the shop floor without disturbing adjacent machines.

Careful coordination with various agencies and technical team Bajaj Auto Ltd ensured that production is hampered the least. A large pit to accommodate a 15000 LPM central filtration which total tank capacity of more than 1,00,000 liters was constructed outside the shop. U shape gutters were fitted in the trenches and a central filtration was installed in the pit. A regularly tracked project execution ensured on time delivery and smooth transition from individual to Centralized filtration system

Individual tanks were removed and dirty fluid outlets of all machines were connected to the U shaped gutters. These carry the fluid and chips to the CFS. Sufficient gradient ensured all is transferred without any blockage and accumulation. Additional flushing nozzles tapped from high pressure supply line are used at regular intervals.

Coolant life increased from 3 months to 3 years. New machines were added due to the space saved by removing individual tanks. Manpower was reduced. Lesser breakdown and downtime of machines increased production capacities. Power consumption was reduced by 50%
