In an air flow classifier that centrifugally separates the raw material into fine powder and coarse powder in the classification chamber, a raw material supply tube is provided on the upper part of the peripheral wall of the dispersion chamber for supplying the raw material in a tangential direction to the outer circumference of the dispersion chamber. A number of louvers are provided at equal intervals in the circumferential direction and are inclined downward in the direction of rotation of the raw material depending on the connection position of the raw material supply cylinder, and a secondary air inflow path is formed between adjacent louvers. Features: Airflow classifier. (2) The air classifier according to claim (1), wherein the louvers arranged in the circumferential direction are provided in multiple stages in the vertical direction. (3) Claim (1) wherein an annular passage is formed on the outside of the louver provided in the circumferential direction, and a damper for adjusting the opening is attached to the air intake port provided in the annular passage.
) or the air classifier described in (2).
