BACKGROUND The ball mill works on the principle of impact between the rapidly moving balls and the materials .Both the balls and the sample are enclosed in a hollow cylinder. 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 ...
