Using DEM to investigate how shell liner can induce ball

Jun 01, 2020 We particularly focus on the way balls diffuse axially within the mills. As can be seen in Fig. 8, the concentration of smaller balls is slightly high at the product end of the mill whilst that of bigger balls is slightly high at the feed end of the mill. This is evidence that liner configuration affects ball segregation inside the mill.

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.
