Effect of ball and feed particle size distribution on the

Jun 01, 2018 The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower. For a finer feed, the 20 mm 10 mm binary mix is able to break the feed at a faster rate.
