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.
At a certain speed, the centrifugal force causes the ground sample material and grinding balls to separate from the inner wall of the grinding bowl The grinding balls then cross the bowl at high speed and further grind the sample material by impact against the opposite bowl wall
