The Influence of Slurry Rheology on Ultra-Fine Grinding in .

This paper presents the experimental results on the effects of slurry Theology on ultra-fine grinding by a stirred ball mill. The amount of dispersant, slurry density and the particle size were selected as the parameters. The viscosity of dolomite-water slurry was measured by rotational viscometers. It was found that by adding enough dispersant, the effect.

Cost optimization of stirred ball mill grinding .

Because stirred ball mills have a high capital cost per unit volume the trade off between energy consumption and capacity becomes critical. This paper presents a generalized total cost mode for stirred ball milling and examines data generated in the grinding of oil shales in terms of the model.

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.
