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.
