Abstract: When material is thrown in a hopper, material of small particle diameter is loaded in between breaking teeth on two rotors and transferred toward a crushing space between the rotors by rotation. The material of small particle diameter is pressed by compression teeth on one rotor against cutting teeth on the other rotor, thereby causing compressive crushing. When material of small particle diameter clogs the crushing space and stays therein, the cutting teeth cut the material to form a gap. The breaking teeth on the two rotors move odd-shaped material or the like toward the crushing space by similar action. Consequently, the odd-shaped material assumes such a posture that it is caught between the breaking teeth, and is crushed by the breaking teeth or cut by the wedge effect.
