Spin Flash Dryer

The special cooling device is set at the bottom of the rotary flash dryer to avoid the deterioration of materials in the high temperature area at the bottom.

The special air pressure sealing device and bearing cooling device of the rotary flash dryer can effectively prolong the service life of the transmission part.

The special air distribution device of the rotary flash dryer reduces the resistance of the equipment and effectively provides the processing air volume of the dryer.

The drying chamber of the rotary flash dryer is equipped with a grading ring and a swirl plate, and the material fineness and final moisture can be adjusted. (for example, the final moisture content of calcium carbonate can be adjusted to ≤ 0.1%)

Compared with other drying methods, SXG series quick rotary flash dryer can effectively increase the specific gravity of materials.

The rotary flash dryer has high circumferential gas velocity and short material residence time in the drying chamber, which can effectively prevent materials from sticking to the wall and deterioration of heat sensitive materials, and achieve high efficiency, fast, small equipment and large-scale production.

The hot air of the rotary flash dryer enters the stirring and crushing drying chamber from the bottom of the dryer at a suitable spouting speed from the inlet pipe of the SXG series fast rotating flash dryer, which has strong shearing, blowing and rotating effects on the materials. Therefore, the materials are divided and granulated by centrifugation, shearing, collision and friction, thus strengthening the mass and heat transfer. At the bottom of the dryer, the larger and wetter particles are mechanically broken under the action of the agitator, and the particles with lower moisture content and smaller particle size are entrained and lifted by the rotating airflow, and further dried in the rising process. Due to the rotating flow of gas and solid, the inertia of solid phase is greater than that of gas phase, and the relative velocity of solid phase and gas phase is larger, so the mass transfer and heat transfer between two phases are strengthened, so the production intensity of the machine is high.
