A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

McLanahan specializes in a variety of crushing solutions to reduce ROM coal to a transportable and marketable top size. McLanahan crushers can take the coal producer through all stages of crushing process, from initial reduction in the primary stage to further reduction and refinement in the secondary and tertiary stages, all while minimizing the generation of dust and fines.
Generally, a Quad Roll Crusher is recommended for a medium size feed material, while the Triple Roll Crusher, with its single roll top stage, is effective for handling larger size feeds. These machines do the work normally assigned to two separate crushers. Typical feed sizes range from 18" 72" with final product size of ½" 3".
4. Introduction: • Objective of CHP is to supply the quanta of processed coal to bunkers of Coal mills for Boiler operation and to stack the coal to coal storage area. • Coal is a hard black or dark brown sedimentary rock formed by the decomposition of plant material, widely used as a fuel. • A piece of coal called Coal Lumps.

Some small coal processing plants have been known to use jaw crushers, but this is probably a result of special circumstances that make it easier to obtain such crushers than a purposebuilt coal crusher, and not due to any superiority of the jaw crusher in operation. Coal sizing: an introduction
17. INPLANT COAL HANDLING The InPlant coal handling system deals with feeding of coal from live storage to the furnace. It includes various equipment's for transfer of coal like belt conveyor, screw conveyor etc. the equipment needed to weigh the quantity of coal for feed. In case of pulverized coal firing system, it requires large no. of equipment's like chutes, pulverized mills, feeders ...
Primary coal crusher: Used for larger coal size. The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is ...
Coal transport by truck is quite common for use in industrial boilers and small power plants of up to 200 MW capacities. Depending upon the number of trucks to be unloaded, methods used for unloading coal from the trucks differ. Methods such as manual unloading with help of shovels, rear dump trucks, truck tipplers are used. Coal Storage:
Coal crushing plant consist of many types of crushers and mills. These coal crushing machine is not used lonely, they compose a complete crushing plant with belt conveyor and vibrating screen. In Electric Power plant, coal gasification and clean coal process, crushing process is the first step and essential step.
These types of crushers are usually applied as tertiary or quaternary crushers with less than 2" (75 mm) feed or smaller. Some Vertical Shaft Impactors can be used as secondary crushers with larger feed. Vertical Shaft Impactors are very applicationspecific. They are sensitive to abrasive materials and can experience very high maintenance ...
There are two types of impact crushers: horizontal shaft impactor and vertical shaft impactor. Impact crushers are suitable for materials that are soft or easily cleaving from the surface. The crusher consists of a fast spinning rotor and beaters attached to the rotor. The feed is entering to the crusher from the top and crushing starts ...
As shown in Figure 2, coal and preheated primary air first enter the crusher section. Here the coal is im pacted on a grid section by swing hammers, reducing the coal to a nominal 1/4" size. Drying of the coal also occurs in this section. After the coal passes through the grid section, it enters the twostage pulverizing sec tion.
Crushers play an important role in the material handling process for underground mine operations. The main purpose of a crusher is the size reduction of the feed. This size reduction is achieved by applying a force to the material, creating cracks in the material which in the end will cause the material to break into smaller pieces.
