2.1.2 Critical Speed If the peripheral speed of the mill is very high it begins to act like a centrifuge and the balls do not fall back but stay on the perimeter of the mill and that point is called the "Critical Speed" (n c).This phenomenon is called centrifuging. Ball mills usually operate at 65 to 75 of the critical speed.
