It is very noisy machine. 3. Ball mill is a slow process. 4. Soft and sticky material cannot be milled by ball mill 5. At low speed, the balls will slide or roll over each other and only negligible amount of size reduction will occur. 6. At high speed the balls will be thrown out to the wall by centrifugal force and no grinding will occur.

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.
