Effect of ball and feed particle size distribution

· For the feed sample sizes investigated the three ball mix was more effective for the coarser feed due to the presence of the 50 mm balls whilst with a finer feed the binary mix gave the optimal amount of size class of interest These results prove that a close control of feed and ball match is of paramount importance if one is to improve the efficiency of milling circuits
