As a key piece of equipment in industries such as mineral processing and construction waste treatment, the stability and efficiency of the jaw crusher have a crucial impact on the entire production line. Against this backdrop, the thrust plate, as an important component in the jaw crusher, naturally becomes the focus of maintenance work in terms of its function and replacement method. This article will provide a detailed introduction to the role of thrust plates in jaw crushers and how to replace them.
First, the function of the thrust plate of the jaw crusher
The thrust plate, also known as the rear toggle plate, is one of the important components of the jaw crusher. Its main function is to bear and transmit the torque generated by the motor and working mechanism, drive the movable jaw plate to move back and forth, and achieve the crushing of materials. The thrust plate, through its connection with the frame, forms a stable support structure, ensuring the stable operation of the crusher. Meanwhile, the thrust plate also plays a certain supporting and protective role, providing reliable support for other components of the crusher and preventing debris and foreign objects from entering the crushing chamber.
Second, the replacement method of the thrust plate of the jaw crusher
1. Shutdown for maintenance: Firstly, the jaw crusher needs to be shut down and the power supply cut off to ensure the safety of operation. Then, conduct a comprehensive inspection of the crusher and clean the crushing cavity and other related components.
2. Remove the original thrust plate: Use appropriate tools to remove the bolts connecting the thrust plate. Please ensure that the operation is stable during disassembly and handle the thrust plate carefully to avoid injury.
3. Install the new thrust plate: After confirming that the crushing chamber is clean and free of foreign objects, install the new thrust plate on the jaw crusher. Connect the thrust plate to the movable jaw plate and the adjusting seat, and gradually tighten the bolts, but do not over-tighten them.
4. Adjust the position of the thrust plate: The position and Angle of the thrust plate have a significant impact on the crushing effect of the crusher. By adjusting the position and Angle of the thrust plate, the gap between the jaw plates can be changed, thereby adjusting the size of the discharge port. Adjust the position and Angle of the thrust plate appropriately according to actual needs.
5. Trial operation and commissioning: After the replacement of the thrust plate is completed, conduct a trial operation and commissioning. Before starting the machine, make sure all the connecting bolts have been tightened and check whether all the indicators of the crusher are normal. Then, start the trial operation and observe the operation of the crusher.
