2012-2-13.5. Converting AG to SAG milling and grinding performance. An important prerequisite to convert AG to SAG mills was to assure that the mill fillings was above 20. On two occasions the mill was crash stopped and the fillings were found to be 22 and 26. To provide 5 vv balls, 21 t balls with sizes and amounts shown in Table 2 were added.

Figures 8 and 9 on the right show results from a gold plant’s SAG mill achieved with MillStar’s Segregated Ore Feed Controller combined with the Power Optimiser: • The standard deviation of the mill feed control is greatly reduced. • The cyclone feed is more stable, allowing for consistent size separation and feed to downstream processes.

In comparison to conventional tumbling mills, i.e., rod-and ball mills, the grinding media in an AG mill derive from the feed ore itself (Gupta and Yan, 2016;Hahne et al., 2003).
