is added to assist in size reduction. This is known as a SemiAutogeneous (SAG) mill. AG mills bring about size reduction by a combination of impact, attrition and abrasion forces. The ore is swept up one side of the mill and at a certain point it falls back to impact the toe of the charge at the bottom of the mill.
The IsaMill is a stirredmedium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older highthroughput mills (such as ball mills and rod mills). Stirred mills often consist of stirrers mounted on a rotating shaft located along the central axis of the mill.

Iron ore grinding is completed in the ball mill, so the Iron ore ball mill is the main place for ore materials. Just like other ball mills, the Iron ore ball mill is mainly composed by a feeding part, an exhaust end, a rotation, and transmission part(a reduction box, an electrical machine, an electronic control, and pinion drive gear) and other ...
mills in the older plants that had many mills in parallel. In fact this is generally still the case in the multistream plants, where mill liner design and selection is only tackled on a cost consumables basis. However, the gains to be had through good liner design and selection are just as great as on the large SAG mills.
The benchmark circuit varies with plant capacity and ore competency: • Single stage crush/single stage SAG mills and two stage crush/ball mill circuits are typically selected for low throughput plants (<50 t/h) where personnel costs are a large component of costs. • .
