grinding stirred consumption

Mill (grinding)

Like ball mills, grinding (steel) balls or pebbles are often added to stirred mills to help grind ore, however these mills contain a large screw mounted vertically to lift and grind material In tower mills, there is no cascading action as in standard grinding mills Stirred mills are also common for mixing quicklime (CaO) into a lime slurry...

Stirred Ball Milling

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...
