Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many lowgrade, high ...
In addition to the new process equipment, the SAG mill was commissioned with all controls implemented on the new PLC software platform. This removed the control strategy limitations previously described. Additional mill control loops and measurements now included: Mill feed tonnage (automatic PI control – operator or remote setpoint from mill
That does not mean that the preference is speed control over feed rate control. Each ore is different and each plant is different. As equipment designers, we have to provide each of the features that the operators could use to optimize their process. In my experience, SAG Mills are normally variable speed, and Ball Mills are normally fixed speed.
