Rotation Of Ball Mill At Critical Speed Material Science

Rotation Of Ball Mill At Critical Speed  Material Science

Aug 06 2015 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
