Comparison and difference between ultrafine powder dryer and rotary flash dryer
Flash evaporation dryer is one of the rapidly developing and widely used models, also known as cyclone dryer or rotary fast dryer in China. The flash dryer organically combines fluidization, swirling, spraying, crushing, and grading technologies, and is an optimized combination of fluidization technology, swirling technology, spraying technology, and convective heat transfer technology. The equipment has a high technical content and is suitable for drying paste like, granular, filter cake like, and slurry like materials.
Flash drying machine has the advantages of high thermal efficiency, short drying time, and good energy-saving effect. The paste like materials can be directly dried to produce powdered dried products, saving the processes of pre-treatment before drying, crushing, screening, etc. after drying; Due to the fast drying speed and short heating time of the material, it is not easy to damage the components of the dried material, which is particularly beneficial for drying heat sensitive materials; The drying process is fully enclosed, with no impurities mixed in, resulting in high-quality finished products and a good operating environment. At present, various models of flash dryers have been designed according to different materials, and a series of products have been formed, with increasingly wide applications in industries such as chemical, pharmaceutical, light industry, food, and mineral.
Typical dry materials include:
Inorganic substances: 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, iron oxide red, aluminum hydroxide, sodium acetate, white carbon black, bentonite, etc.
