Fluidized Bed

The most commonly used and best-suited medium for fluidized bed processes is fused aluminum oxide grains. This process involves the use of a high-temperature chamber that introduces gas through a distributor plate, thereby creating an ideal atmosphere for bed levitation. When the force exerted by the gas equals the weight of the medium, a fluidized state is achieved. This technology significantly enhances the lifespan of precision tools, aircraft, automobiles, and other transportation equipment components.

Currently, fluidized bed technology has been applied in areas such as wire annealing, biomass gasification, and the pyrolysis of solid waste. In the applications of biomass and waste pyrolysis, brown aluminum oxide is favored for its excellent attrition resistance and the potential catalytic benefits its aluminum content could provide due to its alumina content.

Moreover, in the later stages of particle production, calcination is employed to remove any dust adhering to the surface of the particles.
