SAG Mill

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

Application

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.

Project Cases

SAG mill for magnetite LIMS magnetic separation

Single stage SAG Mill was beneficial in reducing CAPEX, when tonnage increased, the SAG Mill can feed downstream ball milling to boost capacity.

SAG mill for gold CIL plant

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.

SAG Mill for gold flotation plant

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 Mill for cooper flotation plant

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.

SAG Mill for lithium ore flotation

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.

SAG mill for nickel ore grinding

The specific extraction of nickel concentrates taken depend on whether the nickel ore is a sulfide or a laterite.

SAG mill for bauxite grinding

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.

SAG Mill for cobalt flotation plant

The new cobalt recovery technique is a beneficiation process which uses a combination of fine grinding and froth flotation.
