The flash dryer has the advantages of high thermal efficiency, short drying time, and good energy saving effect. The paste-like material can be directly dried to produce a powdery dry product, which saves pre-drying, drying, crushing, screening and other processes; due to the fast drying speed, the material heating time is short, and it is not easy to damage the components of the dry material, especially It is beneficial to the drying of heat-sensitive materials; the drying process is completely closed, no impurities are mixed in, the quality of finished products is high, and the operating environment is good. At present, the flash dryer has designed a variety of models based on different materials, and formed a series of products, which have become increasingly widespread in the chemical, pharmaceutical, light industry, food, minerals, and other industries.
Typical dry materials are:
Inorganic: borax, calcium carbonate, hydroxide, copper sulfate, iron oxide, strontium carbonate, antimony trioxide, various heavy metal salts, synthetic cryolite, manganese carbonate, magnesium carbonate, sodium sulfite, calcium hydrogen phosphate, alumina, oxidation Iron red, aluminum hydroxide, sodium acetate, white carbon black, bentonite, etc.

Flash dryer overview and scope of application
Flash dryer is one of the most widely used drying equipment types in the world. It is also known as spin dryer and rotary fast dryer in China. The flash dryer is organically combined with fluidization, swirling, jetting, smashing, and grading technologies. It is an optimized combination of fluidization technology, swirling technology, spouting technology, and convection heat transfer technology. The technical content of the equipment is high. Suitable for the drying of paste, granule, filter cake and muddy materials.
