The crushing rotor 400 rotates eccentrically, so that the waste and slag entering the crushing rotor 400 and the surface of the crushing drum 320 are crushed and crushed under the movement of the crushing rotor 400, so that large block structures are reduced to smaller gravel and freely fall to the surface of the static crushing disk 300. Under the rotation of the crushing rod 410, the moving teeth 420 and the fixed teeth 310 are used to shear and crush the stones, and after the crushing is completed, they are discharged from the feeding hopper 110 and the first discharge port 120 through the discharge grid hole 321.
