Function Function Of Classifier In Coal Mill

coal mill pulverizer in thermal power plants. Nov 17, 2012 9. 4.4.Classification The circulating air is also used to classify the pulverized coal product prior to carrying it to the burners. The classifier, located on the top of a mill returns the over-size material back to the pulverizer but allows the proper-sized material to pass out of the mill to the burners. classifiers are critical

Fundamentally, the air classifier inside the coal mill filters the fine coal particles through the loss of momentum caused by the collisions between coal particles and the blades of the . classifier [23]. This procedure represents the filtering process of the ground coal whereby the coal classifier allows the finer coal particles to pass

Jan 23, 2018 There are two types of classifier: static and dynamic. Both use centrifugal force to carry out the classification function. In the static classifier the coal particles are passed through an angled vane structure. Heavier particles collide with the vanes, lose energy and fall back into the grinder

The classification function plays the important role of ensuring that only fine particles of the pulverized coal are sent to the boiler. Within a rotating-type classifier, fine particles are passed through while coarse particles are eliminated by utilizing the relative balance of centrifugal force and centripetal force produced by a blade
