This results normally in air temperature of 5 [°C] below cement temperature at mill discharge. Higher temperature differences point to higher false air rates. ♦ The mill exhaust air temperature must always be kept > 30 [°C] above the dew point temperature (t) to avoid condensation problems. Excessive false air favors condensation.
