Abstract
An apparatus for preventing uneven distributions of coal fines in the upper, outlet end of a coal mill classifier. A plurality of static diffuser elements is positioned in the upper end of the classifier, preferably within the classifier skirt if the classifier includes such structure, adjacent the inlets of multiple coal discharge pipes leading from the upper end of the classifier to a combustion chamber. In a preferred form the diffuser elements comprise vertically-arranged toothed bars mounted on the inside wall surfaces of the skirt.
