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.

Between 80% and critical there is a small difference of 2% to 5% with the continuous ball size distribution being lower. For supercritical speeds, the continuous ball case shows a significant reduction in power consumption of 2025%. This demonstrates that the power draw is sensitive to even small changes in the ball distribution.
