A Comparison of Three Types of Coal Pulverizers

Properly sized pulverized coal exits the classifier into coal piping for transport to the furnace. Oversized pro- duct is, however, separated and returned to the mill for further grinding. There is minimal metal-to-metal contact of the grinding elements in the BTM resulting in very little wear and low maintenance.

Coal mill pulverizer in thermal power plants

Nov 17, 2012· 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 in providing the

Classification performance of model coal mill classifiers

Mar 01, 2020· 1. Introduction. The classification performance of the air classifier in a vertical coal mill determines the size of pulverized coal particles. Thus, the classification performance will influence the ignition, burning, and burnout of the coal particle, and NO x formation in the furnace as well [,,, ].The first generation of the coal mill classifier used static guide vanes to produce a

Jul 15, 2007· Most existing pulverizers—both the vertical-shaft and ball-mill types—come with a static classifier. Its blades reject coarse particles to produce a stream of coal particles that are mostly

Coal pulverisation The Nature Of Science

Before the coal can be used in the power station, it has to be crushed into fine dust. This is sometimes done in grinding machinery which uses large toothed wheels whose teeth interlock. As the wheels rotate against each other, lumps of coal are trapped between the teeth and are crushed, much like a massive
