摘要： When a broken piece of a crushed material is caught and locked between the bottom plate of a hopper and a crusher body, the locked broken piece can be released automatically. A hydraulic motor (54) for a feeder which is used to reciprocatingly move the bottom plate of the hopper, and a valve (50) for a feeder which is adapted to supply a pressure oil, which is discharged from a hydraulic pump, to first and second ports (54a, 54b) of the hydraulic motor (54) for a feeder are provided. The valve (50) for a feeder is adapted to be shifted to a first position B when an electric current is supplied to a first solenoid (55), and to a second position C when an electric current is supplied to a second solenoid (56). A keep relay (59) for supplying an electric current to the first and second solenoids (55, 56), and first and second pressure switches (57, 58) adapted to be turned on when the pressures in the first and second ports (54a, 54b) become not lower than set levels are provided. The first and second pressure switches (57, 58) and keep relay (59) are provided so that, when the first or second pressure switch (57) or (58) is turned on, the first or second solenoid (55) or (56) is reversely energized.
