Abstract
A classification system using a fluidized bed according to the present invention includes: a fluidized bed classifier supplied with powder containing particles of different sizes, which entrains the powder into the fluidized gas, and then discharges coarse powder through a coarse powder outlet positioned in its lower portion. The system further includes a cyclone communicating with an upper portion of the fluidized bed classifier, which collects and discharges fine powder contained in the fluidized gas transferred from the fluidized bed classifier to a fine powder outlet positioned in its lower portion. Additionally, the system further includes a plurality of internal structures positioned in the fluidized bed in the fluidized bed classifier which reduce a size of a bubble of the fluidized gas.
