AG/SAG is short for autogenous mill and semi-autogenous mill, it combines with two functions of crushing and grinding, uses the ground material itself as the grinding media and this is the biggest difference compared with ball mill, through the mutual impact and grinding action to gradually reduce the material size.
Diameter: 4000 mm-9000 mm
Power: up to 9000KW
SAG or AG mill are mainly used in the large scale minerals processing plant include gold ore, copper ore, cobalt ore, nickel ore, graphite, lithium ore, spodumene, coal, silver ore, iron ore, lead and zinc ore.
The particle size of the materials to be ground by SAG mill is 300 ~ 400mm, and the minimum product size of SAG mill to be discharged can reach 0.1 mm.
Single stage SAG Mill was beneficial in reducing CAPEX, when tonnage increased, the SAG Mill can feed downstream ball milling to boost capacity.
In order to improve the processing capacity of the mill, a small amount of steel balls be added appropriately, usually occupying 2-3% of the volume of the mill (that is semi-autogenous grinding).
SAG mills play an important role in copper ore mining by efficiently breaking down large chunks of material into manageable sizes while also using less energy.
Ground lithium ore in sodium hydroxide or sodium carbonate, after agitation and washing, the fatty acid is added as a collector to directly float the spodumene.
The specific extraction of nickel concentrates taken depend on whether the nickel ore is a sulfide or a laterite.
Grinding of bauxite as feed to alumina refineries is undertaken in a variety of grinding circuit types utilizing a range of mill types such as Rod/Ball Mills, AG/SAG Circuits.
The new cobalt recovery technique is a beneficiation process which uses a combination of fine grinding and froth flotation.
