SINGLE STAGE SAG/AG MILLING DESIGN - Orway

2014-10-1  If determined to be reasonably power-efficient, single stage SAG milling is likely to be a comparatively profitable grinding circuit design. xMedium Grind – 80% passing size between 106 and 75 µm. To mill in single stage SAG configuration, the feed must be consistent and the downstream process reasonably capable of handling some fluctuations ...
