Mill Critical Speed Formula Derivation  Grinding ...
The formula to calculate critical speed is given below. N c = 42.305 /sqt(Dd) N c = critical speed of the mill. D = mill diameter specified in meters. d = diameter of the ball. In practice Ball Mills are driven at a speed of 5090% of the critical speed, the factor being influenced by economic consideration.

Ball Mill Operating Speed  Mechanical Operations Solved ...
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.
