Ball Mill Grinding P80 Size. The mesh of grinding usually lies between 48 and 200 mesh. On account of their size in relation to that of the bubbles, particles larger than 48 mesh generally have too great a tendency to drop out of the froth and escape in the tailing, while the lower limit is determined by the fact that grinding finer than 200 ...

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.
