Features
1. A variety of feeding devices are available for selection. The feeding is continuous and stable, and there will be no bridging during the process.
2. A special cooling device is installed at the bottom of the dryer to prevent the material from deteriorating in the high temperature area at the bottom.
3. Special air pressure sealing device and bearing cooling device effectively extend the service life of the transmission part.
4. The special air distribution device reduces the equipment resistance and effectively provides the processing air volume of the dryer.
5. The drying chamber is equipped with a classification ring and a swirling sheet, and the fineness and final moisture content of the material are adjustable. (For example, the final moisture content of calcium carbonate can be adjusted to ≤0. 1%)
6. Compared with other drying methods, it can effectively increase the proportion of materials.
7. The circumferential air velocity in the drying chamber is high and the material residence time is short, which effectively prevents the material from sticking to the wall and the deterioration of heat-sensitive materials, achieving high efficiency, speed, small equipment, and large-scale production.
working principle
The hot air enters the mixing and grinding drying chamber from the bottom of the dryer at a suitable spraying speed through the inlet pipe, exerting strong shearing, blowing and rotating effects on the materials. As a result, the materials are subjected to centrifugal shearing, collision and friction and are micronized. Enhanced mass and heat transfer.At the bottom of the dryer, the larger and wetter particle clusters are mechanically broken under the action of the agitator, and the particles with lower moisture content and smaller particle size are entrained and raised by the rotating airflow, and are further dried during the rising process.Since the gas and solid phases rotate and flow, the inertia of the solid phase is greater than that of the gas phase, and the relative speed between the solid and gas phases is larger, which strengthens the mass and heat transfer between the two phases, so the production intensity of this machine is high.
Inorganic: boric acid, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various metal hydroxides, various heavy metal salts, synthetic cryolite, etc.;
Organic matter: atrazine (pesticides), lauric acid, benzoic acid, benzoic acid, fungicide, sodium oxalate, cellulose acetate, etc.;
Ceramics: kaolin, silica, clay;
Dyes: anthraquinone, black iron oxide, indigo pigment, butyric acid, titanium hydroxide, zinc sulfide, various azo dye intermediates;
Food: soy protein, gelatinized starch, distiller's grains, wheat sugar, wheat starch, etc.
