The rotor rejects the coarse particles to be collected by the guide vanes and returned via the reject cone to the grinding table for further grinding, while the air and the finished material leave the separator via the outlet duct. The fineness of the ground product can be adjusted by varying the speed of the rotor.
· In coal milling for power stations, a 'closedloop' process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the recirculation loop is within the mill, but some mill types would have an external loop.
· Gainful utilization of coal ash can deliver positive natural, financial and execution advantages, for example, decreased utilization of assets, lower ozone harming substance outflows, diminished cost of coal ash removal, and further developed strength and solidness of materials.

clear that the utilization of this waste slack coal becomes a serious economic consideration. When the coal is suitable for the production of coke, the utilization of the slack presents no difficulty, as it is in demand for that purpose. If the coal does not produce good coke, but cakes rather readily, the slack can be used for boiler purposes, as it fuses together more or less .
· Smoldering coal inside an idle mill can evolve into a big problem when the mill is started, agitating these accumulation combined with a high air to fuel ratio environment; PRB is one of the most difficult coals with respect to mill fires and explosions. Mill internal temperatures are generally high enough somewhere to ignite any type ofcoal ...
slow speed drum mill or drumtube mill, medium speed vertical spindle mills such as ball and race, bowl mill, NEI/LM mills, high speed hammer mill/beater mill, or tan mills. 3 Effect of Coal Quality The majority of power coal is of noncaking bituminous or subbituminous rank except on few occasions when anthracite is used. Lignite is also used ...

· Specifically, fineness is a measurement of the percentage of a coal sample that passes through a set of test sieves usually designated at 50, 100, and 200 mesh A 70% coal sample passing through a 200 mesh screen indies optimum mill performance. The mill wear and the power consumption are increased if the 70% value is exceeded. Values lower than .
