Prove Of Critical Speed Of Ball Mill

The ability to simulate the bond work index test also allows examination of truncated ball mill feed size distributions on the work index.For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill see figure 3.10, a question arises as to whether this practice will alter the ball mill work index bw i of the material.
