how do coal classifiers work

  • POWER PLANT TO PRODUCT

    coarse fly ash drops out of the classifiers and Coal Mills. The coal is then conveyed to storage silos and metered to the coal mills the fine particles referred to as fly ash because they exit the burn zone with flue gases via the duct work.

  • Pulverizer - Wikipedia

    A pulverizer or grinder is a mechanical device for the grinding of many different types of materials. For example, a pulverizer mill is used to pulverize coal for combustion in the The coarse particles rejected in the classifier are returned to the mill for another cycle of grinding. In order to avoid excess sweeping of coal from
