WhatsApp: +86 18838072829As 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 18838072829Working Principle of a SAG Mill. The rock and grinding media are placed in the mill and rotated, causing the grinding media to tumble and crush the rock into smaller pieces. The mill operates in a closed circuit with screens that size the ore and send it back to the mill for further grinding. The product from the mill is then sent to a cyclone ...

WhatsApp: +86 18838072829The RoM mill evolved from pebble tube mills used for fine secondary grinding that were converted to primary mills by directing the full runofmine feed to them rather than just the handselected pebbles, Mokk:en (1978). This successfully eliminated the need for the primary ball mill.
