A drive motor is installed on the side wall of the crushing chamber, and the output end of the drive motor is fixedly connected to the crushing rollers. A secondary crushing component is used to crush the raw material again, and the secondary crushing component is located inside the crushing chamber.

[0006] The crushing roller is driven by a drive motor to rotate and crush and compress the raw material. The unqualified raw material falls onto the secondary crushing component, which performs secondary crushing operation on the raw material. This improves the crushing capacity, makes the raw material crushed more uniformly, and improves the crushing quality.

[0007] Furthermore, the secondary crushing component includes a crushing roller, a crushing bottom plate is fixedly connected inside the crushing chamber, guide grooves are provided on both sides of the crushing chamber, guide sliders are slidably connected in the guide grooves, a movable side plate is fixedly connected on the guide slider, the movable side plate is movably connected to the inner wall of the crushing chamber, the crushing roller is rotatably connected between the two movable side plates, and the crushing roller is located above the crushing bottom plate.
