Metal hydroxide rotary flash drying machine
Working principle
At the bottom of the metal hydroxide rotary flash dryer, larger and wetter particle clusters are mechanically crushed under the action of the agitator, while particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process. Due to the rotational flow of the gas and solid 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 relatively large, which enhances the mass and heat transfer between the two phases. Therefore, this machine has a high production intensity.
Product Features
High efficiency drying : The rotary flash dryer effectively breaks and disperses the material through the high-speed rotating airflow and stirring blades, increasing the surface area of the material and thereby improving the drying efficiency. High circumferential gas velocity in drying chamber, short residence time of material, can complete the drying process efficiently and quickly .
Wide range of applications : This equipment is suitable for pasty materials, filter cakes, thixotropic materials, heat-sensitive materials, as well as granular and powdered materials. Because of its efficient drying effect, it is particularly suitable for handling perishable or hard-to-dry materials .
Compact structure : The rotary flash dryer is relatively small in size, typically 1/4 to 1/10 that of spray drying equipment with the same production capacity, which enables it to achieve efficient production in a limited space .
Energy saving and environmental protection : Rotary flash dryer improves thermal efficiency and reduces energy consumption through efficient heat exchange and gas-solid mixing. Meanwhile, its closed operation design reduces DUST escape, no POLLUTION to the environment .
Easy to operate : The equipment has a simple structure, is easy to manufacture and install, and has low maintenance cost. The final moisture and fineness can be effectively controlled by adjusting parameters such as supply, hot air temperature, classifier, etc. to ensure product consistency .
To prevent sticking and deterioration : Special cooling and air pressure sealing devices are installed at the bottom of the dryer to prevent the material from deteriorating in the high-temperature zone. Meanwhile, SPECIAL air distribution device and air pressure sealing device effectively prevent material sticking to the wall phenomenon .
