WhatsApp: +86 18838072829We 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.
