 · Coal fineness can be varied in the pulverizer by a number of measures which include varying the coal feed rate, the classifier settings, or the air flow rate. Although mills can be tuned to suit a particular coal to produce the required size, this is not practical in case of a coal blend where a large number of coals are being used. In such case some of the coal constituents may not achieve ...
