WEBBall mills are often operated at higher speeds than rod mills, so that the larger balls aract 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.
