Critical speed is defined as the point at which the centrifugal force applied to the grinding mill charge is equal to the force of gravity. at critical speed, the grinding mill charge clings to the mill inner surface and does not tumble. most ball mills operate at approximately 75% critical speed, as this is determined to be the optimum speed
Critical speed (cs) is the speed at which the grinding media will centrifuge against the wall of the cylinder. obviously no milling will occur when the media is pinned against the cylinder so operating speed will be some percentage of the cs. the formula for critical speed is cs = 1/2π √(g/(r-r) where g is the gravitational constant, r is
