To provide a pulverizer by which raw material is smoothly fed to a pulverizing means.

Chaff is fed to a hole part 28 between a rotor 32 and a housing 30 from a feeding path 16 by the rotation of an impeller 18. At this time, since the impeller 18 and the rotor 32 are rotated in directions opposite to each other, the chaff reaching between the impeller 18 and the rotor 32 is guided by both the impeller 18 and rotor 32 and is smoothly pushed into the hole part 28 between the rotor 32 and the housing 30. Since the impeller 18 is arranged in the feeding path 16 on the downstream side in the rotation direction (on the left side from a central line CL), force is not applied to the chaff reaching the vicinity of the rotor 32 in the opposite direction from the rotor 32 and the impeller 18 to cause no bridge phenomenon or the like. Therefore, the chaff can be smoothly fed to the pulverizing means.
