If ventilating effect is good while exhausted-gas temperature is higher than 100℃, you can equip the rotary dryer with groups of X-shape lifting boards as much as possible. While, if ventilating effect is poor while exhausted-gas temperature is lower than 70℃, X-shape lifting boards to be installed for rotary dryer should be as few as possible.
