Working principle:

With a certain spouted speed, hot-air enters into mixing-grinding dry room from the bottom of drier by inlet pipe. To the materials, a strong wind shear, wind float and spin are forced. So that, the materials turn to be micronized by centrifugal, cutting, collision, friction to strengthen the mass and heat transfer. At the bottom of drier, the larger and wetter cluster of grains are shattered under the action of blender, but the less wet and smaller grains will be carried up by swirling eddy and to be further dried. Because of the rotation flow of gas and solid two phases, and solid-phase has the larger inertia than gas-pahse, the relative speed of them is much larger to strengthen the mass and heat transfer between each other. Therefore the drier has the strong production intensity.

Features:

1.  As the materials turn to be micronized by centrifugal, cutting, collision, friction and to be highly decentralized state. Moreover, the larger relative speed of solid-gas two phases has strengthened the mass and heat transfer, this drier has a very strong production intensity.

2. Dry air enters into the bottom of drier and produces a strong rotating flow, so that to wash out the materials on the wall and to eliminate stick phenomenon.

3. At the high-temperature area of the drier bottom, heat-sensitivity materials do not contact with heat surface directly, moreover, it also has equipped with special device to slove the coking and color changed problems of heat-sensitivity materials.  

4. Because of the circumferential gas velocity in drier room is higher and the materials stay time is shorter, it can be high-speed, rapid, small equipment and large production.

5. There are elutriate ring and swirl plate on the top of dry room to control the granularity and humidity of outlet materials, so that to achieve the final water granularity requirements of different materials.
