ABSTRACT:
A classification apparatus including a magnetic stirrer composed of main body (1) and rotor (2) and, arranged on the main body of the magnetic stirrer, classification tube (3). The interior of the classification tube is provided with classification compartments (A-E) partitioned from each other by divider plates (5a-5b). The lowermost classification compartment (A) is furnished with gas emission conduit (7). In the classification compartment (A), the rotor (2) of the magnetic stirrer is arranged. From gas supply source (8), a high-pressure gas is fed into the gas emission conduit. By means of the gas emitted from the gas emission conduit, a vortex flow rising from the lowermost classification compartment sequentially toward higher classification compartments is generated in the classification tube. Simultaneously, the rotor of the magnetic stirrer is rotated, so that powdery substance (O) within the classification compartment (A), while being conveyed by the vortex flow, undergoes particle size classification in each of the classification compartments.
