A pulverizing apparatus for processing a processing-object powder material that can be readily melted by friction heat generated between the pulverizing apparatus and the material. The pulverizing apparatus includes a casing (2) having a cylindrical inner face, a rotor (10) driven to rotate about the axis X of the casing (2) and having a rugged portion (10G) in its outer periphery, a gas flow forming means (26) for forming a gas flow for conveying the powder material from a feed opening (3) provided at an end of the casing (2) along the axis X direction to a discharge opening (4) provided at the other axial end of the casing (2), a coolant supplying means (P) for causing coolant to flow in a coolant passage (15) formed inside the rotor (10), and a coolant circuit (23). The rugged portion (10G) is divided along the axis X direction by an annular cutout portion (11) extended along the peripheral direction of the rotor (10). |
