what is the critical speed of ball mill
what is the 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 of50-90% of the critical speed, the factor being influenced by economic consideration.
