Sag Mill Pooling Issues

Optimizing your SAG mill operation - International Mining

21-03-2022 · 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 operate at

Modelling the influence on power draw of the slurry phase

The slurry level in AG/SAG and ball mills has an influence on their power draw, which in some instances can be profound. This is particularly the case with so-called slurry pooling in AG/SAG mills which can result in significant lowering of power draw. From a predictive viewpoint there are currently no published models that explicitly describe the influence of slurry level on power
