    Coal mill pulverizer in thermal power plants

    Nov 17, 2012 4.1.Drying The coal that is passing through a pulverizer is entrained by the use of hot air usually from the air heater. During the pulverization process the surface area of the coal particles increases dramatically exposing fresh coal to the entrainment air. The inherent and surface moisture of the coal is reduced by the exposure to hot air. read more
