Formatted abstract Scanalyse in collaboration with JKMRC and Newcrest Mining Limited conducted an extensive study of the effect of liner wear on mill performance of a 32 foot SAG mill at Newcrest's Cadia Valley Operations in Australia. The methodology of determining the optimum liner shape was previously presented at Metplant 2011, and expanded on at the SAG11. The results presented indicated that liners with a reduced mass and shorter life outperform their longer life counter parts in all key production parameters of throughput, energy consumption and product size. This paper quantifies the benefit of having shorter liner life cycles for improved performance by calculating the increase in throughput and reduction in power based on historical data for an operational 32 foot mill. It also presents the total overall gain by accounting for the increase in required reline effort. This provides a holistic view of the net achievements when designing liners for performance and not life.
