Liner wear in primary mills is reported to be greater than the wear on crushing surfaces and mill liners in a crushing and grinding circuit. Overall savings in steel consumed are estimated to be 55% to 60% of the cost of rod and sometimes ball wear. Savings in semiautogenous milling should be less due to ball wear and increased liner wear.

Abstract Product fineness during grinding in stirred media mills is mainly influenced by the specific energy input, the stress energy transferred by the colliding grinding media and the stress frequency. The stress energy from grinding media collisions is heterogeneously distributed in stirred media mills.

This study presents an approach for targeted comminution of component mixtures within a wetoperated stirred media mill. In the first step, a general understanding of the interactions between individual components on the grinding result with mixtures could be gained with basic experiments and following our former research work. In particular, a protective effect of the coarser particles on the ...
