Classification performance of model coal mill

2020-3-1  In a vertical coal mill, coal is often ground at the bottom of the classifier and then the pulverized coal particles are blown up to the rotating impeller mounted at the top. So far, most of the experimental measurements and numerical simulations have been conducted only at a given inlet condition of the incoming two-phase flow from the bottom of the air classifier [ [29] , [30] , [31] ].
