Comminution - Mineral Processing & Metallurgy

As an example of this fallacy may be cited the use of the results of tests carried out upon a ball mill. From Chapter 3, it is easily seen that the change in particle size has practically no effect upon the power to drive a ball mill and so the energy input to the mill is proportional to the time of milling, as in Fig. 4.2.
