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.

Ball mill is a cylindrical grinder having three different compartments and screen. Replaceable liners or balls are fixed inside entire mill. Ball mills contain different sizes of balls as a grinding media.
