Critical speed is one of the most important design considerations of a ball mill Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity At critical speed, the grinding mill charge clings to the mill inner surface and does not tumble...

Ball mill

If the peripheral speed of the mill is too great, it begins to act like a centrifuge and the balls do not fall back, but stay on the perimeter of the mill The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed...
