Technologies for extraction and processing, including gearless mill drives (GMDs) and gearless conveyor drives (GCDs), help operators save energy and achieve greater throughput at large mills with higher grinding capacities. When big data is also applied, this lowers costs using preventive and predictive maintenance.

The main drawback of SAG - high power consumption. To reduce power consumption, I think: 1. The right determine of SAG feed size. This depends on the mill diameter and the ball size. Feed size necessary to take 80% of the maximum piece of ore that will crushed by the balls. For the big SAG more than 8 meters optimal feed size will be - 50mm.

Mark Child: That's correct, so the mill that we've purchased is a big SAG mill, it's brand new with 18 month warranty, its 2,300t/day. With a slightly bigger motor it can be 20% bigger at 2,800t/day so the FS level designs we've done are laid out to double that capacity.

SAG mill. SAG stands for Semi-Autogenous Grinding. Just like ball mills, these machines also have grinding balls in them. Actually, a SAG mill is used as a primary stage solution for grinding. It comes with a 28 MW motor and a diameter of 44 inches. As a matter of fact these machines are used at platinum, copper and gold mines.

The biggest characteristic of the sag mill is that the crushing ratio is large. The particle size of the materials to be ground is 300 ~ 400mm, sometimes even larger, and the minimum particle size of the materials to be discharged can reach 0.1 mm. The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill's ...
