The primary air input to a ball tube mill performs a dual function. It is used for drying and as the fuel transport medium, and by regulating it the mill output is regulated. Governed by the pulverized fuel outlet temperature requirement, the cold air and hot air dampers are regulated to achieve the correct primary air temperature.
