Semi-autogenous grinding (SAG) mill liner design and

Mill liners provide the replaceable wear-resistant surface within grinding mills; they also impart the grind-ing action to the mill charge, and at the discharge end, remove the ground contents of the mill. In recent years, as SAG mills have grown in size, the process aspects of liner design and their impact on mill performance have

SAG Mill Liner Design Mineral Processing & Metallurgy

06/06/2016 Based on experience, mill-liner designs have moved toward more open-shell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebble-crushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of 2.5:1 and 5.0:1.
