In this paper, we carried out batch grinding tests of silica glass, limestone and gypsum with a ball mill and investigated the effects of feed size and ball diameter on the grinding rate constant (selection function). The results are summarized as follows; 1. Variation of the dimensionless grinding rate constant with feed size was roughly ...
