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.

Planetary ball mills often show shorter reaction times compared to mixer mills. This might be caused by the more frequent creation of new surface by the sheering motion as compared to the direct impact which rather compresses the powder present on the active surface. 23 It might also be the case that the higher energy input in planetary ball ...

Inside mixer/vibratory and planetary ball mills, balls collide at relatively high velocities, and pulsed ball impacts dominate the mechanical energy input. In attritor ball mills, the ball velocities can be lower than in the previous types, leading to frictional dynamics in which shear forces are also important [ 9 ].
