Flash dryer is one of the most widely developed drying equipment models. It is also called rotary dryer and rotary quick dryer in China. The flash dryer organically combines fluidization, swirling, spouting, pulverizing and grading techniques. It is an optimized combination of fluidization technology, swirling technology, spray technology and convection heat transfer technology. The technical content of the equipment is high. It is suitable for the drying of paste, granule, filter cake and mud materials.
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 form a powdery dry product, which saves the steps of pre-drying pretreatment, pulverization after drying, sieving, etc.; due to the fast drying speed, the material is heated for a short time, and it is not easy to destroy 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 finished product is of high quality and the operating environment is good. At present, the flash dryer has designed a variety of models according to different materials, and has formed a series of products, which are more and more widely used in the chemical, pharmaceutical, light industry, food, mineral and other industries.
The more typical dry materials are:
Inorganic materials: borax, calcium carbonate, hydroxide, copper sulfate, iron oxide, barium carbonate, antimony trioxide, various heavy metal salts, synthetic cryolite, manganese carbonate, magnesium carbonate, sodium sulfite, calcium hydrogen phosphate, aluminum oxide, oxidation Iron red, aluminum hydroxide, sodium acetate, white carbon black, bentonite, and the like.
