principle

Hot air enters the mixing and crushing drying chamber from the bottom of the dryer at a suitable spraying speed through the air inlet, exerting strong shearing, blowing, and rotating effects on the material. As a result, the material is subjected to centrifugation, shearing, collision, and friction, leading to particle formation and enhanced mass and heat transfer. At the bottom of the dryer, larger and wetter particle clusters are mechanically crushed under the action of the agitator. Particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process. Due to the rotating flow of gas-solid phase, the inertia of solid phase is greater than that of gas phase, and the relative velocity between solid and gas phases is higher, which enhances the heat transfer effect between the two phases. Therefore, the drying intensity of this machine is high.

  characteristic

Multiple feeding devices are available for selection, ensuring continuous and stable feeding without any bridging phenomenon.
A special cooling device is installed at the bottom of the dryer to prevent material deterioration in the high-temperature zone at the bottom.
Special pneumatic sealing device and bearing cooling device effectively extend the service life of the transmission part.
The special air distribution device reduces equipment resistance and balances the wind speed inside the tower.

The drying room is equipped with grading rings and swirl blades, and the material fineness and final moisture content can be adjusted and controlled.
