The jet mill comprises a gas mill main body and a conveying box, a feeding hopper is mounted on the outer surface of the gas mill main body, the conveying box is mounted on the outer surface of the feeding hopper, a placing box is mounted on the upper surface of the conveying box, and a rotating sleeve is mounted on the inner surface of the conveying box; a rotating shaft is embedded in the inner surface of the rotating sleeve, a rotating plate is mounted on the outer surface of the rotating shaft, a mounting rod is mounted on the outer surface of the rotating plate, and threaded conveying blades are mounted on the outer surface of the mounting rod. According to the airflow pulverizer capable of achieving graded backflow pulverizing, the power gear is driven to rotate by controlling the conveying motor, and the rotating shaft is driven to rotate by means of meshing between the power gear and the gear chain and meshing between the transmission gear and the gear chain; and thus, the threaded conveying blades ca
