SAG circuits may employ low to relatively high ball charges (ranging from 2% to 22%, expressed as volumetric mill filling) to augment autogenous media. Higher ball charges shift the breakage mode away from attrition and abrasion breakage toward impact breakage; as a result, AG milling produces a finer grind than SAG milling for a given ore and

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. Seepage results in process water loss,
