    • 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.
    • 一种分级装置,包括由主体(1)和转子(2)组成的磁力搅拌器,并且配置在磁力搅拌器的主体上,分级管(3)。 分级管的内部设置有通过分隔板(5a-5b)彼此分隔的分级室(A-E)。 最下面的分类室(A)配有气体排放导管(7)。 在分级室(A)中,设置磁力搅拌器的转子(2)。 从气体供给源(8)向高压气体供给气体。 通过从气体排放导管排出的气体,在分级管中产生从最下层分级室顺序向上分级室升起的涡流。 同时旋转磁力搅拌器的转子,使分类室(A)内的粉末状物质(O)在被涡流输送的同时在每个分级室中进行粒度分级。
