Mar 01, 2020 · The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber. The impeller is a cage with a set of blades installed around its outer ring. It introduces a secondary classification by the collision effect in addition to the primary classification by centrifugal force [ [11], [12], [13] ].

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.
