Flash drying machine - Overview of testing equipment
The XMG - Φ 300 rotary grinding flash drying machine is a new type of drying equipment developed by our company independently, based on the introduction of advanced foreign technology. This device has many advantages such as advanced technology, reasonable design, compact structure, wide applicability, large production capacity, good product quality, energy saving and high efficiency. At the same time, in a drying equipment, crushing and screening are completed once, eliminating environmental pollution, and the overall performance of the machine reaches the international advanced technology level.

Flash drying machine - working principle of test equipment
Hot air enters the bottom of the rotary flash dryer and forms a strong rotating wind field under the drive of the agitator. When the slurry enters the dryer through the spiral feeder, it is uniformly distributed under the action of impact force, friction force, and shear force. Then, by coming into contact with hot air, the material is quickly crushed, heated, and dried. Dry materials will flow upwards with the hot air flow. At the same time, large particles will be blocked by the grading ring, while small particles will be discharged from the center of the ring and recovered by the cyclone separator and dust collector. Unfinished or large materials are sent to the walls of the equipment by centrifugal force and are crushed and dried again before they fall to the bottom.

Flash drying machine - Application scope of testing equipment
Rotary flash drying machines have many applications, but are more common in mining, used for drying sand, limestone, stones and soil, ores, fertilizers, sawdust, coal, iron sulfate, filter cake, sludge, etc. It can also be applied to the food industry mainly used for liquids, as well as granular substances such as grains, legumes, coffee beans, fermented tea leaves, etc.

Flash drying machine - Characteristics of experimental equipment
1. Multiple feeding devices are available for selection, ensuring continuous and stable feeding without any bridging phenomenon;
2. A special cooling device is installed at the bottom of the dryer to prevent material deterioration in the high-temperature zone at the bottom;
3. Special pneumatic sealing device and bearing cooling device effectively extend the service life of the transmission part;
4. The special air distribution device reduces equipment resistance and balances the wind speed inside the tower;
5. The drying chamber is equipped with a grading ring and swirl blades, and the material fineness and final moisture content can be adjusted and controlled;
6. The high circumferential gas velocity in the drying chamber results in a short residence time of the material, effectively preventing it from sticking to the wall and causing thermal sensitive materials to deteriorate.
