The energy efficiency of ball milling in comminution

The results from various investigations plotted in Fig. 2 can be used to calculate the thermodynamic efficiency of comminution processes. The basis for this is comparison of the surface free energy of quartz as determined by crack extension in air (the results of Brace and Walsh) and the energy expended to produce that surface by any other mode of breakage.
