Spin Flash Dryer for Chemical Materials

WORKING PRINCIPLE
The hot air enters into the bottom of the dryer in tangent direction. Under the driving of the stirrer, a powerful rotating wind field is formed. Paste materials go into the dryer via screw feeder, and dispersed by impact, friction and shearing force under the powerful high-speed rotating impeller; bulk materials immediately get smashed, in fully contact with hot air in order to get heated and dried. Then the dehydrated materials rise with hot air. A hierarchical ring will make large particles retentate, while exhaust small particles out of dryer from center of the ring, recovered by cyclone separator and deduster. The bulk materials or materials without being fully dryer will be thrown to the wall under centrifugal force and drop to the bottom again to be smashed and dried.

FEATURES
(1) Dynamic integration of cyclone, fluidized, spouted and grinding classification technologies.  
(2)  Equipments are compact and small-sized, enabling high efficiency and continuous production, achieving "small equipment, large-scale production".
(3) Great drying intensity, low energy consumption, high thermal efficiency.
(4) Short material residence time, good product quality, available for drying heat sensitive materials.
(5)Negative or slightly negative pressure operation, good impermeability, high efficiency, eliminating environmental pollution.
