Todays ball mills are typically designed to operate with ball charge fillings up to 35% by volume. There are cases where this figure is higher, for example with mill shells designed for higher loadings, but these cases are becoming more rare, with the additional cost of steel becoming prohibitory of this design.

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.
