Abstract
A fluidized bed apparatus has a rotary rotorarranged at the bottom center thereof, a disintegrator mechanismarranged above the rotary rotor, and a cylindrical draft tubeinstalled above the disintegrator mechanism. A fluidizing gas jetted from a gas dispersion platecauses powder particles P in a processing containerto form a fluidized bed in which they circulate so as to ascend through the gap between the outer periphery of the rotary rotorand the bottom inner wall of the processing container, the space between the disintegrator mechanismand the inner wall of the processing container, and the space between the outer periphery of the draft tubeand the inner wall of the processing container, and descend through the inner portion of the draft tube
