As one of the machines widely used in mining, a semiautogenous grinding (SAG) mill can significantly improve the roughing efficiency of rock. But the SAG mill still faces the obstacles of significant energy consumption and empirical operation parameters. In order to obtain the optimal operation parameters of a SAG mill, in this paper, the discrete element method (DEM) is used to simulate the ...

Early SAG mill designs using gear drives were limited in the amount of power that could be applied to the pinions, MPa (5000 hp). The exception to this design was the Hibbing taconite operation. It used MPa (6000 hp) motors to drive a 1Imdiam x long (36ftdiam x 15 ft) autogenous mill. However, recent SAG mill designs now ...
