MODELING OF THE PROCESS OF COAL GRINDING

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.
