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 themill becomes a centrifuge is called the "Critical Speed", andball mills usually operate at 65% to 75% of the critical speed.
