A Comparison of Three Types of Coal Pulverizers
· 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.
