For low volatile coals, the fineness passing between 80-85% through 200 mesh is suitable to avoid carbon loss due to improper combustion. Excessive fineness will lead to wastage of mill power since mill output varies inversely with mill fineness. Hence it is recommended that periodic analyses of coal samples and the proper adjustments of
