Mixing and dispersing device

摘要

A mixing and dispersing device is provided with ante-mixing rotary vanes (130) and post-mixing rotary vanes (150). The ante-mixing rotary vanes (130) are rotatably arranged in a fluidity material side area (E1) and send fluidity material drawn from a radial inside thereof to a first-stage mixing area (E3) being radially outside of a partition plate (120) and induce powder material in a powder side area (E2) to the first-stage mixing area (E3). The post-mixing rotary vanes (150) are arranged in a second-stage mixing area (E4) that is on a downstream side of the first-stage mixing area (E3) and that differs from the first-stage mixing area (E3) in an axial direction, and disperse mixed material of the fluidity material and the powder material flowing from the first-stage mixing area (E3) to the second-stage mixing area (E4) to send out the mixed material to a discharge port (113) being radially outside thereof.
