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
