2020329A ball mill also known as pebble mill or tumbling mill is a milling machine that consists of a hallow cylinder containing balls mounted on a metallic frame such that it can be rotated along its longitudinal axis. The balls which could be of different diameter occupy 30 50 of the mill volume and its sie depends on the feed and mill sie.

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.
