    If the angle of nip is a ratelimiting factor for stirred ball mill grinding, as discussed above, it follows that the optimum Db/Dp ratio of 20:1 should remain constant regardless of ball size. In order to test this hypothesis, the breakage rates shown in Figs. 4 and 5 have been replotted as a function of the Db/Dp ratio, as shown in Fig. 9.
