Technical parameters
1. wood dust drying system
the daying system adopts flowing continuous drying equipment. The wood dust will be mixed with dryed hot air heated by oil boiler. the heat exchange process will be done extensively after they passing through airflow pipes and swirl drying room. The sizes of wood dust granularity is different, some big some small. Affecting by centrifugal force, the big size wood dust stay longer in drying room, the small one stay shortly. It exactly matches the principle that big size wood dust is more difficult to be dehydrated. Small one is easily. The dryed wood dust will be accumulated by swirl separator. The filtered hot air flows into atmosphere.
