The specific design process of rotary flash dryer

▲ The flash dryer has multiple feeding devices to choose from, ensuring continuous and stable feeding without any bridging during the process.

▲ A dedicated cooling device is installed at the bottom of the flash dryer to prevent material deterioration in the high-temperature zone at the bottom.

▲ The special air pressure sealing device and bearing cooling device of the flash dryer effectively extend the service life of the transmission components.

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

▲ The drying chamber of the flash dryer is equipped with grading rings and swirl plates, which can adjust the material fineness and final moisture (such as the final moisture regulator of calcium carbonate, until the final moisture regulator of calcium carbonate is adjustable. ≤ 0.1%)

Compared with other drying methods, the SXG series fast rotating flash drying function effectively improves the material proportion.

▲ The flash dryer has a high circumferential gas velocity in the drying chamber, short material retention time, and effectively prevents strict viscosity barriers and thermal sensitive material deterioration, achieving efficient, fast, small equipment, and large-scale production.

▲ The hot air of the flash dryer rotates rapidly by the SXG series. The inlet pipe of the flash dryer enters the mixing and crushing drying chamber at an appropriate spraying speed from the bottom of the dryer, which has strong shearing, blowing, and rotating effects on the material. Therefore, the material is divided by centrifugation, shearing, collision, and friction, which enhances mass and heat transfer. At the bottom of the dryer, larger and wetter particles are mechanically crushed under the action of the mixer, while particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the rising process. Due to the rotating flow of gas-solid two phases, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the solid and gas phases is greater, which enhances the mass and heat transfer between the two phases. Therefore, the production intensity of this machine is relatively high.
