Estimation of Specific Rate of Grinding to Optimize

2006-11-13  The erosion of the grinding media is monitored by measuring the decrease in the depth of ball bed. The breakage mechanism is studied and the selection function and breakage functions are estimated. These functions are used to solve mass balance equation given in equation (1) which describes the comminution in batch ball mill [2].
