Running Speed is Critical for Ball Grinding Mill ,

May 18, 2013 0183 32 The ball mill rotating speed is called critical speed when the outmost layer balls just rotate with the barrel and don t fall So in the production of used ball mill, to control the critical rotating speed reasonably can realize the effective control on the steel ball consumption Meanwhile the lower on ball consumption will decrease the ore ....

The formula to calculate critical speed is given below N c = 42305 /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...
