COAL PREPARATION AND FIRING

Mills for indirect firing systems can be run at higher volumes if drying requirements are high. Where drying requirements are low, they can operate down to 1.7-1.8 kg/kg. There are advantages in minimising the mill airflow, thus reducing the primary air level. However mill output and drying capacity can be limited, possibly affecting kiln output.
