Abstract
A pneumatic pulverizer includes an accelerating tube for conveying and accelerating a material to be pulverlized by a high-pressure gas and a pulverizing chamber for finely pulverizing the material to be pulverized. The pulverizing chamber is provided with a colliding member having a colliding surface provided in opposed relation to an outlet of the accelerating tube. The colliding surface of the colliding member has a protruding central portion, and an outer peripheral colliding surface provided around the protruding central portion for secondarily pulverizing the material primarily pulverized by the protruding central portion. The pulverizing chamber has a side wall for performing tertiary pulverization on the material secondarily pulverized by the outer peripheral colliding surface.
