LONGLY spray drying one-stop solution provides spray dryers for slurry drying and powdering, or turnkey projects with a spray dryer that covers project research, scheme design, detail demonstration, maintenance, commissioning, construction, and installation. The slurry pumped into the spray drying chamber is atomized and granulated through the nozzle or high-speed rotating atomizing disc. After continuous contact with hot air, the atomized liquid is instantly dried at high temperatures to form powders. Most powders are collected by the discharge port at the bottom of the chamber. Exhaust gas and tiny dust are separated using filters, cyclone separators, and others. The exhaust fan outlet can also be equipped with a secondary dust removal device, with a recovery rate of more than 96-98%.
