A pharmaceutical ball mill is a type of grinder that is used to grind and combine materials in the production of different dosage forms. Impact reduces the size of the balls as they fall from near the top of the shell. Ball mills are commonly used in single stage fine grinding, regrinding, and as the second stage in twostage grinding circuits.
