Rod Mills may be considered either fine crushers or coarse grinding equipment. They are capable of taking as large as 2″ feed and making a product as fine as 3548 mesh. Of particular advantage is their adaptability to handling wet sticky ores, which normally would cause difficulty in crushing operations.

The hammer mill, feed conveyor, and auger in the feed bin are controlled with sensing units so that the mill cannot be over fed and jam up. As the amps on the hammer mill climb the feed auger slows, when the amps reach a preset limit the feed conveyor stops to allow the hammer mill to catch up. This is all 3 phase 240v components. The hammer ...

Based on experience, millliner designs have moved toward more openshell lifter spacing, increased pulp lifter volumetric capacity, and a grate design to facilitate maximizing both pebblecrushing circuit utilization and SAG mill capacity. As a guideline, mill throughput is maximized with shell lifters between ratios of :1 and :1.

Even though it is a relatively minor wear part, the feed chute seal affects performance, lifecycle and safety in the SAG mill and a failure can be disastrous in more ways than just time and money. One of the main issues with poor sealing between the SAG mill inlet chute and mill itself is the failure to retain water inside.
