Abstract :
Coal pulverizers have utilized a static classifier to generate the desired product fineness which could be effectively burned in a kiln, furnace or boiler. Now there is interest in obtaining a finer product that can enhance the burning efficiency in a coal fired kiln. This is important in light of the increased use of petroleum coke rather than conventional coal. Previously, a secondary fuel would be required to act as a sustainer for the coke due to it´s lower volatile content. The turbine style dynamic classifier appears to meet the needs for a new generation classifier to produce the higher product fineness of the ground material
