coal mill classifier vanes

The first generation of the coal mill classifier used static guide vanes to produce a swirling flow to classify the particles by centrifugal force 5-10 . 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.

Coal Millan overview ScienceDirect Topics

In coal milling for power stations a closed-loop process is used in which the rejects from the classifier are returned to the mill for regrinding. In VSMs the re-circulation loop is within the mill but some mill types would have an external loop.

Dynamic classifiers a fine way to help achieve lower

There have been very few conversions of UK coal mills from static to dynamic classifiers. But test experience with a dynamic classifier at Powergen s Ratcliffe-on-Soar power station has demonstrated significant fineness gain especially at the coarse end of the particle size distribution curve and minimal effect on mill coal throughput and operability with greatly reduced in vibration levels.

he Flapper Valves on the MPS and MBF are designed to catch coal that has been rejected at the classifier level. The weight of the accumulated reject coal trips the Flapper Door and releases it for regrind. Air flow studies show that coal released from the Flapper Assembly falls into the air stream and can be carried back through the classifier
