# Mining Formula For Critical Speed 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.

• ### Choosing A Sag Mill To Achieve Design Performance

A further explanation is required to explain the importance of designing the sag mill chamber to draw required power at optimum operating conditions of 75 critical speed and less than 30 by volume load.Recent studies in the three-foot diameter sag mill are instructive.The following graph shows the relevant facts as figure 2.
