SAG Mill Grinding Circuit Design - 911metallurgist. It can be very difficult operationally to trade grind for throughput in an SAG circuit—once designed and constructed for a given circuit configuration, an SAG mill circuit has limited flexibility to deliver varying product sizes, and a relatively fixed unit power input for a given ore type is typically required in the SAG mill.

Autogenous and SemiAutogenous Mills ScienceDirect The SAG mills have been mostly used for milling hard gold and copper ores with quartz, ultramafic or green stone as host rocks The Bond work index of these ores ranges between 12 and 14 kWh/t Subsequently, SAG mill application has been extended to softer ores, such as bauxite and clayey hardcapped gold ores
The inventor, Mr. Lawrence Nordell developed the concept of the CAHM as a by-product of studying SAG mills using DEM (Nordell and Potapov, 2015).It was noticed that 80% of the comminution occurs in a small area (referred to as the 'sweet spot'), inside the SAG mill, where 10 times higher shear work is observed than in the other areas of the mill (see Fig. 1).
