2018-6-1  For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. 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.

2016-3-21  The changing particle size distribution of the milled good as a function of time is mosteasy to characterize qualitatively if the material has initially only one particle size. Atthe start of milling the first size class is continually diminished, (Curve A Fig. 3) firstfaster and then slower. An average particle size class is initially built up. With furthermilling time this size class reaches a maximum percentage (Curve B Fig. 3) since thisclass is milled to a smaller particle size class. Very small particle size classes evolvewith time during the milling
