    My experience has shown that the Bond mill operating at the condition specified by Bond (1961) cannot break particles of a typical hard ore coarser than 3.35mm. Maxson et al. (1934) also found that minus 3.35mm is small enough to be broken by a grinding mill with the same dimensions and operating condition as the Bond mill. 2.6.
