The following are factors that have been investigated and applied in conventional ball milling in order to maximize grinding efficiency: a) Mill Geometry and Speed – Bond (1954) observed grinding efficiency to be a function of ball mill diameter, and established empirical relationships for recommended media size and mill speed that take this factor into account.

Ball mills may be able to efficiently reduce coarse aggregate to particles as small as 30 to 40 microns. Below 30 microns, the advantages of a horizontal stirred mill become dramatic and below a certain point, the horizontal stirred mill is the only choice as a ball mill cannot produce a 10 micron product at any practical power consumption.
Vertical spindle mills There are many types of coal mills in use, with one of the most popular types being the pressurised vertical spindle bowl mill as shown in Figure This mill is very popular because it is economical; however, it has very low coal storage so that good control is very important.
An Analytical Model of Coal Abrasiveness Index in Function ... resulting amount of abrasion is therefore proportional to the resulting relative hardness as expressed by the following .
Disclosed is a composition and method from making coal water slurries containing carbon black. A composition disclosed comprises: 65 to 85% by weight coal particulates; to 2% by weight, based on the total weight of dry coal, of carbon black, and optionally to 2% by weight, based on the total weight of the dry coal, of a dispersant.

slope is to be avoided. Vertical transport, however, is a viable concept and has been used in hoisting coal from the pit to the surface. Vertical transport works so well in some instances, that it has been proposed that ground elevation effects be handled by sections of vertical, rather than sloping, pipe in long distance slurry lines.
From the analyzed alkaline metal oxides, all samples can be characterized as sodium feldspar. After that, the Hardgrove grindability test using a ballrace test mill was performed. Hardgrove grindability index of these feldspar samples was averaged to be
