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.

A pharmaceutical ball mill is a type of grinder used to grind and blend materials while manufacturing various dosage forms. The size reduction is done by impact as the balls drop from near the top of the shell. Ball mills are used primarily for singlestage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
