Title: Pulverizer
Inventor: YAMAMOTO SOICHI
IPC: B02C19/22
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a pulverizer in which raw material such as chaff can be pulverized into uniform size by simple structure. SOLUTION: By feeding chaff into a hole part 28 from a feeding hole part 38, blades and edges respectively formed on the outer peripheral surface of a rotor 32 and the inner peripheral surface of a housing 30 are slid to pulverize the chaff. The pulverized chaff is brought out to the outside from a bring-out port 40 through a hole part of a nozzle 16. At this time, since in the bring-out port 40, an adjusting member 36 having a cylindrical part 36a is arranged, an effective conveying direction cross section of the bring-out port 40 is reduced. As a result, conveying resistance of the raw material is increased to prolong residence time of the raw material in the hole part 28. Therefore, by the sliding of the blades of the rotor 32 and the edges of the housing 30, the raw material is pulverized into uniform size.
