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 [ [1], [2], [3], [4] ].
