Jun 01, 2018· Fig. 5 shows the variation ofsizeclass 1 (M1) with the millingtimefor the two feedsizedistributions. For this coarser feed the 50 + 20+10 mmballdiameter mix breaks the material at a faster rate compared to the otherballmatches. The availability of aball sizefor a particular feedsizeensures breakage occurs at a faster rate.
