Abstract. The specific rates of breakage of quartz have been studied in three tumbling ball mills, two of 195 mm and one of m i. d., as a function of fractional ball and powder loading. It was found that power results from a small mill with small lifters were anomalous, probably due to slippage, so that results reported previously from ...
