SAG/Ball Mill Optimization , KnowledgeScape

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.
