The SCHWING fluidized bed process technology is predestined for gas-solids reactions. As a core application, this technology is used in the area of surface modification of innovative, even nano-scale, powders. Especially the usage options for different reaction gases (air, N2, H2, NH3, CO2, O2, Ar, H2O(g), etc.) primarily in the temperature range up to 1100 °C offer a variety of new applications.
Sample applications: Fluidized bed process technique
Many metallic oxides, catalysts, hydroxides, silicates, salts, sulfates, carbon blacks, pigments and graphites are roasted, calcined, reduced, oxidized, activated, passivated, chlorinated, dried, tempered, etc. using fluidized bed processing systems but gases can also be changed on powders through the fluidized bed.
Typical products and applications are:
Fluidized bed process technology is a very versatile technology that can be used to implement and optimize many chemical and physical processes with powdery materials. Fluidized bed technology offers especially many potential process benefits when a good gas/solids contact is desired. The following are required:
Comparison fluidized bed reactor / rotary furnace
In the fluidized bed the product (solids particle) is held in a vertical “gas flow suspension” and thereby ensures optimal process management. Energy-saving potential up to 40% and numerous other benefits make the fluidized bed reactor a true alternative to the rotary furnace (see table for details).
