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 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.
