PROBLEM TO BE SOLVED: To provide a shredder capable of effectively shredding objects to be processed, improving processing efficiency, and easily releasing tangled objects to be processed.SOLUTION: In a casing 10 having an input port 10a and a discharge port 10b for objects to be processed, of a shredder 1, there are disposed a shredding rotor 2 having a shredding blade 4, and a conveyance rotor 3 having an engaging blade 5 so that the shredding rotor 2 is located below the conveyance rotor 3 in a vertical direction. The shredding rotor 2 and the conveyance rotor 3 are rotatably driven in directions opposite to each other so that the shredding blade 4 and the engaging blade 5 go from the input port 10a toward the discharge port 10b through a part between the rotors. The shredding rotor and the conveyance rotor are driven so that the peripheral speed of the shredding blade 4 of the shredding rotor 2 is equal to or greater than sixteen times the peripheral speed of the engaging blade 5 of the conveyance rotor 3 and less than or equal to twenty times the peripheral speed of the engaging blade 5 of the conveyance rotor 3, thus an object to be processed is effectively shredded by the shredding blade 4, being held by the engaging blade 5. |
