A fluidized-bed drying and classifying apparatus is provided with a main body (,) in which a fluidized bed is formed to dry a granular material and to classify the same into fine particles and coarse particles. A perforated gas-distributing plate (,) is disposed in a lower part of a region in which a fluidized bed (,) is formed in the main body (,), a wind box having the shape of a hopper is disposed below the perforated gas-distributing plate. A dropped material discharge device (,) is connected to the lower end of the hopper-shaped wind box (,) to discharge the material dropped into the wind box (,). A gas supply system (,) is connected to the wind box (,) to supply a fluidizing gas that serves as a drying hot gas and a classifying gas into the wind box. A material supply opening portion (,) is mounted to the main body (,) to feed the granular material. A discharge chute (,) is connected to the main body (,) to discharge dried coarse particles. A gas discharge opening portion (,) is connected to the main body (,) to discharge an exhaust gas containing fine particles. The gas supply system (,) includes a flow controller (,) to control classification particle size by controlling the flow rate of the gas supplied into the wind box (,), and a temperature controller (,) to control drying degree through the adjustment of temperature of the hot gas supplied into the wind box (,) according to the adjusted flow rate.

Fluidized-bed drying and classifying apparatus

A multi-chamber fluidized bed classifying apparatus comprising; a main chamber having a fluidized bed arranged on wind boxes, through a perforated gas distributing plate is divided into a drying chamber and a classifying chamber by a partition plate, and a communication passage is defined under the plate. The wind boxes have respective lower ends connected to discharge devices respectively. The wind box is connected to a processing fluidization gas supply system for supplying the fluidization gas into the box, while the wind box is connected to a classifying fluidization gas supply system for supplying the fluidization gas into the box. The classifying fluidization gas supply system is provided with a flow control unit which adjusts the quantity of gas supplied into the classifying chamber to control the size of classified particles. The processing fluidization gas supply system is provided with a control unit, which adjusts the gas quantity and/or the temperature of gas supplied into the drying chamber.
