A 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 size depends on the feed and mill size.

A hardness and structure gradient is usually viewed as undesirable because of faster wear of softer constituents. but the hardness gradient can be exploited to manipulate the ball size distribution of the ball charge to produce better mill grinding capacity and lower ball consumption than is obtained using a ball with harder interior metal.
