    A Ball mill is a horizontal cylinder partly filled with steel balls (or occasionally other shapes) that rotates on its axis imparting a tumbling and cascading action to the balls. Material fed through the mill is crushed by impact and ground by attrition between the balls. The grinding media are usually made of high-chromium steel.The smaller grades are occasionally cylindrical ("pebs A hydropneumatic spring system builds up a pressure of up to 250 Mpa. During operation of the machine it is possible to cchange the pressure and thus change the product fineness. Highly wear-resistant roll surfaces achieve service lives of 4 000 to 10 000 hours when grinding abrasive hard rock.

Mill is lubricated from an integrated oil lubrication system with circulation pump oil filter and cooler thus avoiding external girth gear lubrication cost less space requirement and minor advantage in power consumption. Three stationary grinding rollers roll on a rotating grinding table. The material is drawn in between the rollers and grinding table and ground by pressure and shear. The required pressure forces are produced by a hydropneumatic tension system.

    Coal Mill. Coal mill is used to grind pulverize and dry coal before the coal is transmitted the boiler. It is an important auxiliary machine for coal-powder furnace. It has three methods to produce coal powder --- crushing impacting and grinding. races may rotate against a ball or roll (in a Ring-Roll Mill the rolls may rotate while the ring is stationary). Ring-Roll (Bowl-Mill) and Ball-Race Mills comprise the majority of coal pulverizers currently in service at power generating facilities. Figure 3 shows a cut-away of a Ring-Roll type coal pulverizer.
