The fully fluidized beds exhibit similar properties to liquids. The fluid of the density is smaller than the average density of the bed, which can be suspended on the bed; bed is maintained, and the bed is subjected to hydrostatic relations. That is, the difference of the two sections of the p= ρ GL; particles have a liquid similar to the fluid, can be sprayed from the small holes in the wall of the device; two unicom fluidized beds can adjust the surface of the bed to make it on the same level.
These properties make the processing of granular materials in fluidized beds can be used as continuous flow in and out of materials, and due to the full mixing of particles, the bed temperature, concentration uniformity makes the bed has a unique advantages to be widely applied.
