A Comparison of Three Types of Coal Pulverizers

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. There is minimal metaltometal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.
