# forces involved in size reduction in a ball mill

### Size ReductionVisual Encyclopedia of Chemical Engineering

Pin mills are used to reduce the size of medium- to low-density materials such as talc and clay. Pin mills use centrifugal forces to smash large particles against pins. Equipment Design A colloid mill rotor is an intermeshing rotor used for the size reduction of materials by multiple impacts with the maze of pins.

A Ball Mill Critical Speed (actually ball rod AG or SAG) is the speed at which the centrifugal forces equal gravitational forces at the mill shell s inside surface and no balls will fall from its position onto the shell. The imagery below helps explain what goes on inside a mill as speed varies. Use our online formula The mill speed is typically defined as the percent of the
