The other optimization strategy is to use a multi-objective intelligent optimization algorithm to optimize a SAG mill. In multi-objective optimization, each suboptimization target direction is often di erent, and there are cases where multiple targets cannot be optimized at the same time. Therefore,

SAG mill model. The dynamic model of an AG/SAG mill includes several interlinked sub-process modules, and these modules can be updated individually. As shown in Fig. 1, the mill is divided into n sections, where m is the section number and q is the transported material. All sections have the same length, and each section contains a …

A vibrating screen was used to provide a mill discharge product separation at 19 mm (¾ in.). The minus 76 trail (-3 in.) plus 19 mm (+¾ in.) screen oversize product, which are the "pebbles", were then crushed to essentially minus 19 mm (-¾ in.) in a crushing circuit. This product was returned to the feed end of the mill.

As a result, mines have shifted their emphasis in optimization from ball mills to SAG mills. The rock load in the mill essentially depends on ore characteristics and the discharge rate of broken particles through the discharge end. The discharge rate depends on how efficiently the discharge pump (grate and pulp lifters) operates.
