SAG mills are primarily used at gold, copper and platinum mines where steel balls are used for the grinding. The Manta Controls Advanced Control System, called the SAG Cube, automatically monitors and controls a SAG Mill, keeping track of critical process variables impacting mill throughput.
Mill Vibration Technology. ... It is not a trivial problem and any improvement in these processes can provide a very high rate of return. SAG Mill Power. Finally, the SAG mill power can be optimised to get maximum breakage and throughput. The power-load relationship is highly non-linear and shifts around as the ore hardness and steel load and ...
hemisphere. It employs the world’s largest SAG mill, 40 ft diameter and two 22 ft ball mills in the grinding circuit. In that project, the owners considered it necessary to assess the dynamic response of the foundations for the SAG and ball mills due to vibration problems experienced in other installations. Numerical models of the foundations
• Can be easily retro-fitted to existing mills. The optimal performance of AG/SAG mills is the key to successful plant operation. All AG/SAG mills using radial or curved pulp lifters suffer from inherent material transport problems such as slurry and pebble pooling, which decrease throughput and increase energy consumption.
