SOLUTION: The amount of muck discharged from the chute 9 through a side conveyor 7 is indirectly detected by a muck level detector 21. The amount of waste concrete in a vibration feeder 6 is detected by a high level sensor and a low level sensor in a feeding amount detection part. A controller stops the vibration feeder 6 according to at least one of the amount of muck and the amount of the waste concrete detected. Thus, the crusher can be continuously operated in a state of surely preventing the chute 9 from being clogging with the muck D. COPYRIGHT: (C)2007,JPO&INPIT
