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.

The drive sets the milling drum into slow rotation and the bed of milling media is thus activated i.e. the balls are lifted and then impact back against the bed. Ball mills are usually operated at 75 of the critical speed. The critical speed is the speed where mathematically calculated the grinding media would centrifuge out. Read More

Critical speed (CS) is the speed at which the grinding media will centrifuge against the wall of the cylinder. Obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the CS. The formula for critical speed is CS 1/2 (g/(R-r) where g is the gravitational constant, R is ...
