A Comparison of Three Types of Coal Pulverizers

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.

Coal Pulverizer - Pall

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. Coal that has not been pulverized into fine enough …
