 · 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 semi-autogenous milling should be less due to ball wear and increased liner wear.
