DESIGN OF CYCLONE DE-DUSTER TO INCREASE FINE COAL QUALITY ON CEMENT PLANT
Raw coal is pulverized and dried in coal mill before it’s injected to burner. The cement plant use gas which extracted from top cyclone to reduce coal moisture. That hot gas still contain dust which escaped from top cyclone. <br /> <br /> <br /> <br /> <br...
