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.

With larger balls, or at higher rotation speeds, impact forces become more important during ball milling. Impact forces are used to produce very fine powders. Above a certain critical speed, the balls will be carried around against the cylinder wall under the influence of centrifugal force and comminution or disintegration ceases. 1,2.
