The role of elbow plate in jaw crusher

The elbow plate (commonly referred to as the elbow plate in jaw crushers) plays a crucial role in jaw crushers. Its main functions can be summarized as follows:

1、 Transmitting power

The elbow plate is a key force transmitting component in jaw crushers, and its transmitted power sometimes even exceeds the crushing force. It ensures that the crusher can operate normally, effectively transmitting power to the crushing chamber, and allowing the movable jaw plate to apply sufficient pressure to the material for crushing.

2、 The role of insurance

The elbow board also serves as a safety component. During the crushing process, if non crushing objects (such as metal blocks, oversized stones, etc.) fall into the crushing chamber, these objects may overload the crusher. In order to protect other components of the crusher from damage, the elbow plate will first break, thereby stopping the operation of the crusher. This design effectively prevents serious malfunctions of the crusher caused by overload, reducing maintenance costs and the risk of production interruption.

3、 Adjust the size of the discharge port

In some simple swing jaw crushers, the elbow plate also plays a role in adjusting the size of the discharge port. By replacing elbow plates of different lengths and sizes, the outlet size of the crushing chamber can be changed, thereby controlling the particle size of the final product produced by the crusher. This adjustment function enables the crusher to adapt to different production needs, improving the flexibility and production efficiency of the equipment.

In summary, the elbow plate plays multiple roles in the jaw crusher, including transmitting power, ensuring safety, and adjusting the size of the discharge port. These functions together ensure the stable operation and efficient production of the crusher. Therefore, when selecting the elbow plate, special attention should be paid to its compatibility with the jaw crusher model and durability to ensure the long-term stable operation of the crusher.
