    At low speeds the ball rolled over each other and attrition takes place. 1,2 At critical speed the centrifugal force just occurs as a result the balls are picked up by the mill wall and carried nearly the top where that break contact with the wall and fall to the bottom to be picked up. In this manner impact stress will also be induced and the size reduction made effective.
