Critical speed is the speed at which the centrifugal force is equal to the gravitational force. Normal mill speed is 70 to 80% of the critical speed (Fig 1.3). For example if the critical speed is 18 rpm, mill speed will be 15 rpm. If your mill speed is more than the critical speed and the centrifugal action >
Ball mills are often operated at higher speeds than rod mills, so that the larger balls cataract and impact on the ore particles. The work input to a mill increases in proportion to the speed, and ball mills are run at as high a speed as is possible without centrifuging. Normally this is 70–80% of the critical speed.
