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.
