SAG mill wear optimization using DEM simulation - Rocky DEM
Stopping mill equipment is not a desirable alternative, so the best way to resolve SAG mill challenges is to use simulation technology for equipment design alterations. Replacing the SAG's worn-out liner can occur every six to nine months and cost between $30,000 U.S. and $200,000 U.S. per hour, and each repair takes between 40 hours and 120 hours.

SAG Mill Liner Design - Mineral Processing & Metallurgy
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.
