Dry bulk solids with this fluidized-bed system

The HDC fluidized bed dryer (photo) operates in open systems, as well as in closed, inert-gas loops to keep dried granules in evenly floating, fluidized motion. Besides standard setups for such high-capacity applications as soda, polymer and fertilizer drying, for example, the technology range is also suitable for sophisticated applications requiring higher safety or efficiency standards. These fluidized bed systems are able to handle inflammable, combustible and dust-explosive products, as well as materials with critical flowability, high moisture content or even liquid feed materials. — Andritz Group, Graz, Austria
