coal mill classifier types

Mar 01, 2020· 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, andburnout 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 swirling flow to classify the particles by …
