Optimizing your SAG mill operation - International Mining

2007-3-21  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. The TPL completely eliminates slurry pooling and pebble pooling problems and ensures the best grinding conditions, thus allowing AG/SAG mills to ...
