Chat Online### Rotation of ball mill at critical speedMaterial Science

· If speed of rotation is low it results in insignificant milling action as balls only move in lower part of the drum. If speed of rotation is very high the balls cling to the drum walls due to centrifugal force. Therefore intense grinding action is obtained only when drum rotates at critical speed and here the ball mill rotates at a speed
