Classifier vane for coal mills Sure Alloy Steel Corporation

Abstract: An improved vane of the type adapted for use in the classifier cage of a bowl mill type coal pulverizer. The improved vane is designed such that its lower end extends below the classifier cage inlet when the vane is mounted in the inlet. In a preferred form, the vane has a generally trapezoidal shape with a longer lower edge.

Classification performance of model coal mill classifiers

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 [,,,,, ]. The modern coal mill classifier, however, often has an impeller mounted close to the exit of the mill chamber.
