Coal Mill Classifier Vanes

Sep 16, 1997 a classifier vane adapted to be mounted in the classifier cage inlet, the classifier vane having a lower end designed to extend below the level of the classifier cage inlet to form a coal-directing extension into the classifier cone when the vane is mounted in the classifier cage inlet, wherein the vane comprises an inner vane surface set at a first angle relative to the flow of coal fines past the vane, and further comprises an outer vane

    Mar 01, 2020 The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force [ [5], [6], [7], [8], [9], [10] ]. The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber
