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
Ball mill crushing by tube-mills were first introduced into the crushing departments of cyanide plants when it was found that for crushing finer than 30-mesh other types of crushing machinery were not efficient in order to crush with one pass these mills were made 18 to 22 ft 5 5 to 6 7 m in length pebbles were used as a grinding medium and the mills were lined with either ball mill ...
