Abstract (en)

Disclosed is a milling and classifying apparatus, adapted to produce toner fine particles, comprising a collision mill, and an air classifier, wherein the collision mill comprises a jet nozzle room, a path, a collision plate, and a collision member mounted to a support of the collision plate at downstream of the collision plate, the air classifier comprises a dispersion room and a classification room, the classification room is disposed below the dispersion room, and a flow stabilizer is arranged at a central suction of the separator core to control swirl stream generated within the classification room so as to centrifuge the powder into coarse particles and fine particles by action of the swirl stream.
