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.

centrifugal force in milling powders. For ball milling there is an optimum speed where the centrifugal force at the top of the mill is just balanced by the force of gravity This caused the balls to be lifted to the maximum height before they fall onto the balls below thus imparting the most kinetic energy In practice the ball mill is run at just below this speed 70 80 .

There are three important factors to realize this. (1) Revolution: Moves the material away from the center with centrifugal force. (2) Rotation: Rotation of the container causes flow of the material (rotation and shearing). (3) 45 degrees: Tilting the rotation axis by 45 degrees results in threedimensional flow.
