conditions of shock – abrasive wear [6]. The current structure of the lining in the mill works at high shock loads, and in addition, as a result of the impact of the balls on the surface of the lining under the action of a certain force, the balls are destroyed. The lining experiences a high impact load, and the balls are chipped.

Ball mill Most ball mills, even in primary applications, have a finer ore feed size; this requires some impact but not enough to increase the media consumption or even break the liners. Typically, a ball mill lining has a more rounded profile, often like a sine wave, and the size of the waves is selected based on the size of grinding media used.
