The coal is a very important raw material in the steel industry [6]. It is extracted in the form of solids of con-siderable size and as such form may not generally be burned, sintered or gasifi ed. So it must be properly com-minuted. Grinding of coal generally uses two types of crush-ers, namely, the drum crushers and the hammer crush-ers.


The process in the case of a coal-fired generating station begins when the coal is brought into the station on a conveyor belt after stored in large coal piles just outside the station. The conveyor feeds the coal into large pulverizers that crush the coal into a fine powder, thereby increasing the surface area and allowing it to burn more quickly.
