To provide a crushing method and a crushing system whose size is small and whose safety is high enough to decreasing crushing sizes.

The system has a casing 10, an injection port 10a which is opened at the upper end of the casing 10 to get a cast of objects to be processed discharged from a biaxial shearing-type crushing device, a distributing damper 11 which is slantly disposed so as to section the inside of the casing 10 downwardly of the port 10a and has a plurality of vertical slits, a discharging port 10b that discharges the objects to be processed passing through the slit 11c of the damper 11 to the next process, and a returning port 10d that re-sends the objects to be processed sliding down the damper 11 to the biaxial shearing-type crushing device without passing through it, and discharges only objects to be processed of less than predetermined sizes to the next process. In addition, it is preferable that an erecting means 13 that erects the damper 11 and a scraping means 12 are provided to remove objects to be processed that clog the slits.
