    and flue gas and reduction in moisture evaporation loss. The results show that performance improvement in the 2 to 5 percent range can be achieved by removing 5 to 15 percent of the coal moisture from the baseline value. Predicted variation of the mill exit temperature (temperature of the coal-primary air mixture leaving the mill) with coal information on mill performance with that coal. A curve linking moisture content of the coal with mill capacity shows what reduction in capacity will arise if the moisture is excessive. This is particularly important with ball mills. The particle size distribution and top size may be of importance. For ball mills there is a curve linking mill
