Classifier, Grinding Mill, And Method Of Producing Classifier

Abstract: The purpose of the present invention is to easily provide an attachment section to a blade. This rotary classifier (16) rotates about a central axis (C) extending in the vertical direction, and classifies particles that have been guided by a carrier gas from outside in the radial direction into particles larger than a predetermined particle size and particles at or below the predetermined particle size, said classifier comprising: a main body (70) that rotates about the central axis (C); and a plurality of blades (60) that are supported on the main body (70), extend in the vertical direction, are arranged lined up at predetermined intervals along the circumferential direction about the central axis (C), and repel, at a collision surface, the particles larger than the predetermined particle size. The main body (70) has a plurality of brackets supporting the blades (60). The blades (60) each comprise: a base (62) formed of stainless steel; a hardened section (63) that covers a front surface of the base (62) in a direction of rotation and is formed of a material of a higher hardness than that of the base (62); and an attachment section that is to be fixed to a rear surface of the base (62) in the direction of rotation and attached to the bracket.
