The pulverizer including a pulverization chamber, a jet nozzle, a pulverization nozzle, and a collision member is provided. The pulverization nozzle includes an acceleration tube. The acceleration tube includes an acceleration part A and an acceleration part B. A center (a) of the supply aperture is positioned within the acceleration part A. A point of intersection (b) where central axes of the acceleration tube and the supply aperture intersect is positioned within the acceleration part B. An angle theta formed between the central axes of the acceleration tube and the supply aperture satisfies an inequation 30°@theta<60°.
