Principle: Hot air enters through the inlet pipe into annular space at the bottom of drying chamber and rises spirally; meanwhile, material is added by the feeder into the tower in fixed quantity for full heat exchange with hot air; under the action of mixer, large and wet materials are cracked mechanically, while small-granularity materials with low moisture content are raised by swirling eddy and conveyed to the separator for gas-solid separation; the finished products are collected and packaged, while offgas is exhausted after treatment by the dust collector.

Characteristics: a variety of feeding device for the selection, continuous and stable feeding, process won't produce bridge phenomenon in the middle. At the bottom of the dryer set special cooling device, avoids the phenomenon of material at the bottom of drier metamorphism. Special air pressure seal and bearing cooling device, effectively prolong the service life of transmission parts. Special wind device, reduce the resistance of equipment, and provide the effective of air dryer. Dry indoor circumferential gas velocity is high, the material stay time is short, effectively prevent and metamorphic thermal sensitive material phenomenon of wall material viscosity and achieve efficient, fast, and small equipment, mass production.
