In an SAG mill the dimensions of the mill were 9.75 m × 3.5 m and the specific gravities of the mineral and that of the balls charged were 4.1 and 7.9, respectively.
Jun 01, 2005· If you use very soft rock in a SAG mill it will not work as well as if you use harder rocks. Adjustments to the lifting plates around the circumference of the mill provide greater lift and drop and thus greater efficiency. SAG mills are often used as regrinding mills after a fully autogenous milling. Thus giving them a lower efficiency as they ...

Hard and transition rock is reduced in size through a primary crusher then stacked over two apron feeders for delivery to the mill grinding. Soft rock is fed by excavators through two apron feeders in parallel to the primary crusher, reporting to the grinding circuit on the same conveyor as the hard and transition rock.
SAG is an acronym for Semi-Autogenous Grinding. SAG mills are autogenous mills but use grinding balls like a ball mill. A SAG mill is usually a primary or first stage grinder. SAG mills use a ball charge of 8 to 21%. The largest SAG mill is 42' (12.8m) in diameter, powered by a 28 MW (38,000 HP) motor.
