PROBLEM TO BE SOLVED: To enable an object to be crushed of a larger size than a target grain size to be recrushed without the necessity to perform an operation for transfer to another site or a preliminary installation for transfer and dispense with a complicated wiring/piping operation. SOLUTION: This crushing machine is equipped with a frame 11, a traveling body 10 disposed on the frame 11, a hopper 2 which is installed on one side of the frame 11 and receives an object to be crushed to be charged, a jaw crusher 3 for crushing the object charged from the hopper 2 and a conveyor 5 which carries the object crushed by the jaw crusher 3 to be sent to the other side of the frame 11. In this case, the object crushed by the jaw crusher 3 are sorted out as those below a target grain size and those above the target grain size, and the objects below the target grain size are guided to the conveyor 5 and the objects above the target grain size are discharged to one of the frame 11 using a sieve 7 which is installed between the jaw crusher 3 and the conveyor 5.
