“Blueprint” Your Pulverizer for Improved Performance

The majority of coal pulverizers sized around 120,000 pph use three grinding elements, referred to as journals, rolls, or tires. For best results, all three grind-ing elements should be replaced in matched sets. The concentricity, physical dimensions, and contours must be exactly the same.

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 metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.
