    Ball Mills are generally used to grind material 1/4 inch and finer down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills they must be operated in a closed system with oversize material continuously being recirculated back into the mill to be reduced. The operating principle of the ball mill consists of following steps. In a continuously operating ball mill feed material fed through the central hole one of the caps into the drum and moves therealong being exposed by grinding media. The material grinding occurs during impact falling grinding balls and abrasion the particles between the balls. Then discharge of ground material performed
