AG and SAG mills are coarse grinding devices; they consist of a tumbling drum with 25–40% volume filling of ore. They are fed with runofmine ore or primary crusher product that is around 250 mm. The main modes of breakage are thought to be impact breakage and abrasion.

Sep 06, 2018· A grinding mill is a large tubular machine with a crown gear driven by a pinion, which is driven by a reduction gear and electric motor. Some large SAG mills have what we call a "wrapped" motor drive, which is the motor fields are installed surrounding the entire circumference of the mill, with the mill itself being the stator.

resistance of ore samples to AG/SAG grinding, or 'SAG hardness'. The pilot plant can test coarse feeds (6"), as well as essentially any test conditions, so it presents the lowest degree of scaleup within all the methodologies available. On the negative side, pilot testing is the.
