Theory The ball mill is used for fine grinding of soft materials. Here, the size reduction is done by the impact of ball which are generally 1 to 5 in diameter. The mill operates in batch as well as continuous manner. When the mill is rotated the balls are carried to the top in the mill and they fall down giving an impact on the material.
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.

Abstract Ball mills, like other comminution devices, consume large amounts of energy. Mill operators often have to assess the power draft of mills for an entirely different set of operating conditions or for a reconfigured circuit. It is shown that the power draft can be accurately predicted from analysis of the motion of the charge. The motion of the charge is rigorously simulated with a.
