Internal pulverizer components can be protected from erosion by using Cera-VAM lining, a high-density alumina ceramic. Ceramic-lined panels are available for the pulverizer housing, turret, classifier cone and roll wheel brackets (Figure 7). Special panels can be made to protect just about any internal pulverizer component.

The Raymond Bowl Mill is considered the finest vertical roller mill available for pulverizing coal. The typical Raymond bowl mill system is designed to simultaneously dry, pulverize, and classify solid fuels to 95% passing 200 mesh (<5%R75μ) with a wide range of capacities from 24 to 150 stph.
Pulverizer performance optimization is the first step to a successful combustion optimization program and the inter-relationships of the pulverizers must be considered when attempting to optimize combustion, overall unit performance, operability, reliability, and capacity. Pulverizer capacity seems to be an industry challenge while …
Raw coal enters the top of the pulverizer through the raw coal feed pipe. The raw coal is then pulverized between the roll and rotating ring. Hot air is forced in through the bottom of the pulverizing chamber to remove unwanted moisture and transport the coal dust up through the top of the pulverizer and out the exhaust pipe directly to the burner.
