Claims

[Scope of utility model registration request]

A classification chamber is formed between a guide plate built into the inside of the upper casing and a classification plate built into the inside of the lower casing. A plurality of guide vanes are provided at required intervals in the circumferential direction between the lower ring and the secondary air flowing into the classification chamber from between adjacent guide vanes to accelerate the rotation speed of the powder swirling in the classification chamber. In an air classifier that centrifugally separates powder into fine powder and coarse powder, each of the guide vanes is rotatably supported around a support pin whose both ends are supported by an upper ring and a lower ring, An adjustment ring that is rotatably operated from the outside is installed between the upper ring and the guide vane or between the lower ring and the guide vane, and a guide pin is provided on one side of the opposing surface between the adjustment ring and the guide vane, and the guide pin is inserted into the other side. 1. An air flow classifier characterized in that a guide hole is formed, the guide hole is a long hole, and the guide hole is sloped so that the distance between both ends of the guide hole and the center of the adjustment ring is different.
