Primary air is admitted through the mill, which carries the finest coal particles to mill outlet. The air and coal mixture passes through a classifier, located at the upper part of the mill, where an additional particle separation takes place. Coarser particles return to the coal chute and fine particles are carried to the classifier outlet.
