coal mill proccess

In coal milling for power stations, a‘closed-loop’ process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs, the re-circulation loop is within the mill, but some mill types would have an external loop. In fact, there are a number of re-circulation loops within a mill system.

Coal mill is animportant auxiliary equipment for coal-powder furnace, it has three methods to crush the coal lump and grind them into powder,it is crushing, impacting and grinding. Air swept coal mill is the main equipment in cement plant for both drying and grinding of the powders.

Raw coalfrom the raw coal bunker is supplied to the Coal Mills by a Raw Coal Feeder. The Coal Mills orpulverizer pulverizes the coal to 200 mesh size. The powdered coal from the coal mills is carried to the boiler in coal pipes by high pressure hot air. The pulverized coal air mixture is burnt in the boiler in the combustion zone.
