Classification performance of model coal mill classifiers ...

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] ].
