Micronizing device

Abstract

To provide a micronizing device capable of performing a smooth and satisfactory micronizing process.SOLUTION: This micronizing device comprises: a casing having an inlet and an outlet of a raw material; a first rotary shaft; a rotor having a first rotor part positioned on the inlet side and provided with a plurality of first blades radially installed around the first rotary shaft and a second rotor part positioned on the outlet side and provided with a plurality of second blades radially installed around the first rotary shaft and disposed in the casing; and a liner disposed on the inner surface of the casing along the outer circumference of the rotor. The rotor includes a blade support that supports each of the first blades with respect to the rotor so as to be rotatable around a second rotary positioned closer to the outer circumference side of the rotor than the first rotary shaft.SELECTED DRAWING: Figure 2
