Online servicesThe 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.
Ball mills have been successfully run at speeds between60and90 percentof critical speed, but most mills operate at speeds between65and79 percentof critical speed. Rod mills speed should be limited to a maximum of70% of critical speed and preferably should be in the60 to 68 percentcritical speed range.
