ABSTRACT:
A pulverizer capable of effectively eliminating the production of a back pressure during the pulverization of a material on the pulverization surface of a collision member, to thereby accomplish the pulverization with a high efficiency. A collision member arranged in a pulverization chamber opposite to an injection nozzle is formed with a pulverization surface including a central conical surface section formed so as to project from the collision member in the direction opposite to the direction of injection of a jet and have a conical angle of no less than 30 degrees and an annular surface section formed contiguous to the central conical surface section to surround it and perpendicular to the direction of the jet.
