Critical Speed Equation In A Tumbling Mill. The formula to calculate critical speed is given below. n c = 42.305 /sqt(d-d) 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 50-90% of the critical speed, the factor being influenced by economic consideration.
