Stirred Mill an overview ScienceDirect Topics

A typical stirred mill with a vertical rotating shaft and horizontal arms is shown in Fig. 2.20. This stirring action causes a differential movement between balls and the material being milled, thus a substantially higher degree of surface contact than is achieved in tumbling or vibratory mills is ensured. Milling takes place by impact and

STIRRED MILLING OF NICKEL LATERITES FOR SELECTIVE

and goethitic nickel laterites was investigated to upgrade nickel into the fine fraction using stirred milling. The breakage rates of minerals, grinding time, and the weight ratio of soft and hard minerals in the feed play an important role in selective grinding and nickel upgrade. When the grinding time and breakage rates

IsaMill Wikipedia

The IsaMill is a stirred-medium grinding mill, in which the grinding medium and the ore being ground are stirred rather than being subjected to the tumbling action of older high-throughput 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.
