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 ...

Rod mills, ball mills, autogenous mills, and semiautogenous mills (SAG Mills) all have a number of lubricating and hydraulic systems, and they must work to keep mineral output high. The mill systems oil is subject to extreme levels of very fine particles, and many operators believe the plant should be shut down periodically to change the oil.

Yes, there is no ball mills in that grinding circuit. The p80 to the SAG mill was at about 6" while its product (flotation feed) was at 40 microns. So the answer to your question is yes, a SAG mill can be installed in an operation milling 2,000 tpd and it can be operated efficiently if the operators have the knowledge to operate it well.

In a largescale operation, feed ores are introduced into the AG/SAG mill in a continuous mode at a given flow rate to replace the discharging slurry. Nonetheless, the variations in the feed characteristics, typically hardness and size distribution, could cause sudden disruption to the mill operation. This would be challenging to detect in practice, owing to the hostile environment of the mill ...
