Derivation Of Critical Speed Of Ball 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.

Whatever your requirements, you 'll find the perfect service-oriented solution to match your specific needs with our help.We are here for your questions anytime 24/7, welcome your consultation.
