A crucial parameter that defines the performance of a mill is the energy consumption. The power supplied to the mill is used primarily to lift the load (medium and charge). Additional power is required to keep the mill rotating. 8.1.3 Power drawn by ball, semi-autogenous and autogenous mills A simplified picture of the mill load is shown in Figure
The value of this parameter for CBM is more than OBM for all tests. The value of each morphological parameters of ground particles using minimum size of ball charge (test 1) are quite equals for both mills. In other words, the effect of mill types on particle shape could be negligible with increasing ball surface area.

1 Calculation of ball mill capacity. The production capacity of the ball mill is determined by the amount of material required to be ground, and it must have a certain margin when designing and selecting. There are many factors affecting the production capacity of the ball mill, in addition to the nature of the material (grain size, hardness, density, temperature and humidity), the degree of ...
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
