Working 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 ...

exhibits many of these aspects. Maintaining the SAG mill weight at the optimum value is critical for achieving maximum grind rate efficiency and mill production (Powell,, van der Westhuizen,, Mainza, 2009). However, SAG mill weight is difficult to control as the dynamic response changes as the mill approaches maximum capacity.

To Improve SAG Mill Tonnage but at the risk of being laughed at, another option not used much is to treat the SAG as an AG mill. Use the hard ore as the main grinding media. A fully autogenous (AG) circuits can operate at much lower operating costs, but with limited throughput. The control of AG mills, fed by hard ores and soft components of ...
