Clean coal is known by its low ash content. Most coals contain a large amount of ash, some of which are finely distributed in the coal matrix. With the conventional cleaning process, such ash can not be removed efficiently. From existing coal preparation plants, much middling and highash slime come ...
This paper presents the experimental results on the effects of slurry Theology on ultrafine grinding by a stirred ball mill. The amount of dispersant, slurry density and the particle size were selected as the parameters. The viscosity of dolomitewater slurry was measured by rotational viscometers. It was found that by adding enough dispersant, the effect...
