Equation 1 to drive the corrected power requirement (Rowland, 1982). The equation for Third Theory of Comminution Bond's was originally developed for use with conventional crushing and grinding circuits (crusher-rod-ball mill or crusher-ball mill). By the 1970s, the application of conventional tended to be limited to relatively low capacities.
