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 critical speed of ball mill is given by, where R = radius of ball mill; r = radius of ball. For R = 1000 mm and r = 50 mm, n c = 30.7 rpm. But the mill is operated at a speed of 15 rpm. Therefore, the mill is operated at 100 x 15/30.7 = 48.86 % of critical speed. If 100 mm dia balls are replaced by 50 mm dia balls, and the other conditions
