  • Effects of Mill Performance on Unburnt Carbon in Coal

    Coal particulate fineness for (a) mill 20 and (b) mill 40 Finer sized particles are normally preferred as the smaller surface area allows the volatiles (from coal particulates) to be consumed faster resulting in a higher devolatilization and heat release rate 6 .
