Features:
1. There are multi feeding device for choice. The feeding is continuous, stable and can not have bridging phenomenon.
2. The particular cooling device is equipped on the bottom of dryer, which prevents material from metamorphosing in the high temperature area of bottom.
3. The particular air-pressure sealing device and bearing cooling device can prolong the service life of transmission part effectively.
4. The particular division device reduces equipment’s resistance, and provides dryer’s processing device effectively.
5. The drying room is equipped with grading ring and rotary sheet so that material’s fineness and water content can be adjusted. (Example: water content of calcium carbonate can be regulated to 0.1% lower.)
6. Comparatively to other drying methods, material’s specific gravity can be increased effectively.
7. The air speed around the drying room is very high, so the time for material staying is very short, which can effectively prevent material from sticking on wall and prevent heat sensitive material from metamorphosing, realizing high efficiency, quickness, small equipment and large production.

Working principle;
    Hot air enters into stirring, crushing and drying chamber from the bottom of drier with suitable atomizing speed. It exerts strong shearing, blowing, floating and rotating effect to raw material. Therefore, the raw material is granulated through centrifuge, shearing, impacting and friction effect. It strengthens the process of heat exchange. At the bottom of dryer, the large and damp granule is crushed under the action of stirrer and the granule that is small in particle and contain less moisture will lift accompanied with revolving air stream. During the period of lift, it is dried further. Because gas and solid two phases flow in rotating and the inertia of solid phase is more than that of gas and the relative velocity between solid and gas phases is large, so it strengthens the process of heat exchange. Therefore, the machine has strong drying capacity.
