#### derivation of critical velocity of ball mill

can have a significant effect on the actual critical velocity. Mills usually operate in the range 65 - 82% of critical but values as high as 90% are sometimes used. A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge).
