It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. The axis of the shell may be either horizontal or at a small angle to the horizontal. It is partially filled with balls.

A ball mill rotates its long shaft, and drive a jar which is placed on it. The friction of the rubber surface of the shaft can rotate the jar. The grinding beads (grinding balls) in the jar will constantly hit the sample due to gravity and mechanical force. After a long period of rotation and impact, the sample gradually changes from large pieces to small pieces, and small pieces to powder.

Some of the conclusions drawn from this test are that: (a) The ballmill is naturally a machine of very large capacity; (b) if it is not possible to deliver a large tonnage of original feed to the mill, a closed circuit should be provided so that the mill may crush its own oversize. Closed Circuit Grinding

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.
