As the mill rotates, the balls cascade and pulverize the coal by impact and attrition. The pulverized coal is then conveyed by air to centrifugal classifiers. Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro duct is, however, separated and returned to the mill for further grinding.

· These coal particles then pass through a classifier where the large particles get separated due to centrifugal action and are returned back to the grinding table. Different manufacturers use different type of rollers. "Bowl mills" or Raymond mills use tapered rollers. MPS mill use tire type rollers and are called "roller mills."

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.
