What is the main structure of compound pendulum jaw crusher?

The main structure of a compound pendulum jaw crusher includes:

1. Frame: The frame is the main supporting structure of the crusher, which is composed of two side plates, a front box, and a rear box.

2. Moving jaw: The moving jaw is the main working part of the crusher, which is connected to the frame through a hinge pin and moves back and forth with the help of an eccentric shaft.

3. Fixed jaw: The fixed jaw is the stationary counterpart of the moving jaw, which is fixed to the front box of the frame.

4. Eccentric shaft: The eccentric shaft is the main component that drives the moving jaw to move back and forth. It is installed on the bearing pedestal at the rear of the frame.

5. Toggle plate: The toggle plate connects the moving jaw and the front box of the frame. It helps to transfer the crushing force and prevent overload.

6. Spring: The spring is used to provide the restoring force for the moving jaw when it moves backward after crushing the material.

7. Adjusting device: The adjusting device is used to adjust the size of the discharge port by adjusting the position of the toggle plate.

8. Bearing: The bearing supports the rotation of the eccentric shaft and ensures the smooth operation of the crusher.

In summary, the compound pendulum jaw crusher is composed of a frame, moving jaw, fixed jaw, eccentric shaft, toggle plate, spring, adjusting device, and bearing. The combination of these components enables the crusher to have a high crushing efficiency and capacity.
