Construction of ball mill. It consists of a hollow cylinder that is mounted on a metallic frame in such a way, that it can be rotated on its longitudinal axis. The cylinder contains balls that occupy 3050% of the mill volume The weight of the balls is kept constant. The ball size depends on the size of the feed and the diameter of the mill.

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.
