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. A SAG mill with a 44' (13.4m) diameter and a power of 35 MW (47,000 HP) has been designed. Attrition between grinding balls and ore particles causes grinding of ...

Fewer mills are, however, easier to control and capital and installation costs are lower, so the number of mills must be decided at the design stage. The high unit capacity SAG mill/ball mill circuit is dominant today and has contributed toward substantial savings in capital and operating costs, which has in turn made many low-grade, high ...

supported mills are clearly shown in this diagram. A 10 MW shell supported mill consumes the same foundation space as a 5 MW mill supported on traditional trunnion bearings. This feature provides significant savings in the cost of civil works associated with the mill installation, as well as time required for mill erection and commissioning.
