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.

It pulverizes coal by applying hydraulically-loaded grinding pressure through three grin- ding rollers onto a rotating bed of coal. Grinding pressure can be adjusted to account for variations in coal grindability and desired product fineness. Raw coal is fed through a centrally located feed pipe to the center of the grinding table.

Mill Hp Coal Mill Description. All mill capacities are based on a standard coal with hgi = 50. the larger the value for hgi, the easier it is to grind the coal, resulting in a higher mill capacity. an hgi of 35 reduces the mill capacity about 20%. coals with hgi less than 35 can be pulverized, but mill capacities are reduced significantly..
