  • 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] ]
