The effect of ball size on mill performance

The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d variation of a with ball diameter was found to be of the form ...

Performance comparison of stirred media mill and ball ...

With increasing need for fine and ultrafine grinding, stirred media mills became an alternative for conventional ball mills. In this study, samples of bauxite whose chemical composition and Hardgrove Index values are known were ground to micronized size by a laboratory scale stirred media mill and its performance was compared with a laboratory scale ball (Bond) mill. Stirred media mill ...
