Stirred mills provide better agitation of small grinding media by inducing larger momentum gradient than the tumbling mill. They are recognized to be more efficient than tumbling mills, especially for fine grinding applications. The stirred mill is a fine grinding device capable of producing product particle sizes less than 1 μm.

Introduction. As coarse grained, easily processed ore bodies are depleted, more disseminated, finegrained ores are being treated. Adequate liberation of valuable components within a finegrained ore is often only achieved once the particle size of the ore has been reduced to levels below the traditional ball mill cutoff of 45. μm.. To aid in the economic liberation of finegrained minerals ...
