classifier vane for coal mills

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. The impeller is a cage with a set of blades installed around its outer ring.

INVESTIGATION ON CLASSIFICATION EFFICIENCY FOR COAL

The effect of the settings of the classifier vane angle on the coal classification efficiency was numerically investigated by several researchers 22]. The [2, 20-effect of inlet air velocity, flow vortex and turbulence on the efficiency of a scaled - down model of a static-air classifier was investigated by using a two-dimensional CFD model [2].
