Title:
CLASSIFIER AND CLASSIFYING METHOD
Document Type and Number:
WIPO Patent Application WO/2022/249830
Kind Code:
A1
Abstract:
A classifier (1) includes a casing (2), a rotary body (3), blades (4), a driving part (7), a control unit (8), a tubular member (9), and a bypass flow-path forming member (11). The casing (2) includes a tubular section (20). The rotary body (3) is disposed inside the tubular section (20), and the blades (4) rotate with the rotary body (3). The driving part (7) rotationally drives the rotary body (3). The control unit (8) controls the driving part (7). The tubular section (20) has a gas inlet (21), a gas outlet (22), and a particle discharging port (23). The tubular member (9) has: an internal space (90) communicating with the gas inlet (21); and a powder loading port (93) from which powder is loaded. The bypass flow-path forming member (11) has a bypass flow path (110) communicating with the gas inlet (21) and the gas outlet (22). The control unit (8) controls the rotation speed of the rotary body (3) to change the classification diameter of particles to be discharged from the particle discharging port (23).
