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. Thematerial grindingoccurs duringimpact falling grinding balls and abrasion the particles between the balls. Then,discharge of ground material performedthrough thecentral hole in the discharge cap or through the grid…
