The hot air enters into the bottom of the drier in tangent direction. Under the driving of the stirrer, a powerful rotating wind
field is formed. The paste state materials enter into the drier through the screw feeder. Under the powerful function of the
stirring vanes at high-speed rotation, the materials are distributed under the function of strike, friction and shearing force.
The cake state materials will be smashed and contact the hot air fully and the materials are heated and dried. The dehydrated materials will go up with the hot-air flow. The step rings will stop and keep the big particles. Small particles will be discharged out of the drier from the center of the machine and the material will be collected by cyclone separator of dust collector. The wet or big particles will be swing towards to the wall by the centrifugal force function and the materials will be crushed again after fall down to the bottom.
(1) The raw material is processed by cutting, shearing, blowing, floating, and rotating, then become granulated shape and
separated greatly; the relative velocity between solid phase and gas phase is great, this strengthens the process of heating
exchange.
(2) Design with compact structure and required small occupied area, and the machine is easy to control and maintain.
(3) The hot air enters into the bottom of the machine and creates strong rotating airflow; it can wash out material that sticking on the inside surface.
(4) The high-temperature area is at the bottom of the machine, the heat sensitive raw material will not directly contact with
heating surface. As a result, carbonization and color change problems can be solved.
(5) The dryer is running under negative or micro negative pressure, there is no need other crushing machine to crush raw material, and the circumstance pollution will not occur.
(6) A segmenting ring and a rotational flow piece are equipped in the upper drying room in order to control granulated size and Final moisture to satisfy required moisture containing rate and granulation.
