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 ...

WhatsApp: +86 18838072829The gold ore was assumed to have breakage parameters similar to a bauxite ore for which the breakage parameters were known. The SAG mill used for the simulations was the same mill used for bauxite grinding with known breakage rates [10]. Details of the mill are set out in Table 2. 1272 McKee et al. w m Q. 100 10 [] E!
WhatsApp: +86 18838072829Working: SAG mill make use of steel balls included with some large and hard rocks for grinding. These mills utilize the balls in making the large fragments of materials broken into pieces. The ball charge of a SAG mill is about 9% to 20%.This process takes place inside the large rotating drum of SAG mill which is filled with balls partially.

WhatsApp: +86 18838072829Ball, SAG and rod mills all require their grinding media to be regularly replaced, unlike a HPGR. High Pressure Grinding Rolls have lower maintenance overheads than ball and rod mills, primarily because the grinding media in conventional mills needs to be replaced on a more regular basis. This makes HPGRs more flexible when it comes to meeting ...
WhatsApp: +86 18838072829Different configurations of SAG, ball and rod mill occur but in general a SAG mill can be considered an intermediate stage in breaking down rock from the crushing plant, and feeding to ball or rod mills for further size reduction. Types of mill Different types of mill are in operation rod or ball mills, so
