Operating comminution circuits without grinding …

This predicament might force some sites to modify their grinding circuit operating strategies from semi-autogenous milling (SAG - with grinding media) to autogenous milling (AG - without grinding media). Other operations might reconfigure the grinding circuit entirely to operate without ball mills (i.e. in single-stage AG operation) to maintain ...

Autogenous and Semi-Autogenous Mills | FL

Semi-autogenous grinding uses a minimal ball charge in the range of 6-15% while autogenous grinding uses ore only. ... The mills can be operated in open circuit, feeding downstream secondary grinding, or operated in closed circuit as single stage mills generating a finer product size. Single stage SAG Mills are very beneficial in reducing CAPEX ...
