AG & SAG Mills Curved Pulp Lifters - 911 Metallurgist
A curved pulp lifter and curved composite cantilever grate system was retro-fitted to the Northparkes 24 ft SAG Mill (the Bradken "Vortex" design). The principal process objective with this mill was to provide a capability "to pump rocks". Up to 30% of oversize is being recirculated to the mills via recycle crushers.
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.
