Optimizing your SAG mill operation International Mining

Mar 21, 2007· As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.get price

SAG/Ball KnowledgeScape Expert Systems, Optimization

The results in SAG-Mill line 2 are even more dramatic. Because of segregation on the coarse feed stockpile, SAG-mill 2 receives a higher percentage of coarse material. The KnowledgeScape strategy’s ability to maintain smooth and stable operation of the mill was more apparent when contrasted to the DCS control on the “difficult” line.get price
