If a ball mill contained only coarse particles, then 100 of the mill grinding volume and power draw would be applied to the grinding of coarse particles. in reality, the mill always contains fines these fines are present in the ball mill feed and are produced as the particles pass through the mill.
By mill operating parameters. it is hoped that this work can be used as a precursor to the development of a model that can predict liberation given the various ranges of operating parameters. mill speed, mill charge, ball size, and wet grinding are the parameters which have been selected for the present study. it is hoped that the analysis of the
