  • Coal Mill  An Overview  Sciencedirect Topics

    Coal Mill An Overview Sciencedirect Topics

    Drying of the coal occurs through contact with the heated air (and surfaces) within the mill; From the fluidising zone the ground coal is lifted up inside the Mill Body. Larger particles of coal reach a terminal velocity at which gravity will pull them back on to the Grinding Table for regrinding (Elutriation);
