Uniquely the SAG Mill can use Grinding Balls made from various materials to increase energy efficiency PDF The Effect of Grinding Media Shape on the Specific The effect of the shape of grinding media on the breakage parameters of colemanite has been investigated in kinetic studies In this present research three different monosize

While in conventional tumbling mills the size reduction is primarily by impact of grinding media steel balls or rods in AG or SAG mills the size reduction is mainly by abrasion and chipping off of particles and less so by impact The process is complicated by 1 the grinding

Optimising the charge motion to ensure grinding media is hitting the toe of the charge will result in the maximising of ore breakage rates and therefore mill throughput Trajectory analysis also ensures grinding media is not being over thrown onto mill liners where the impact can lead to breakage of balls and liners therefore minimising
