Regarding the repair methods of the jaw crusher, the repair methods of different defects are different, so for this problem, we mainly introduce the repair methods of the common defects of the core parts, and hope to help you:
    1. Repair of thrust plate of jaw crusher The thrust plate of jaw crusher is *ly made of cast iron, and the thrust plate seat is *ly cast steel or modified cast iron. The thrust plate plays the effect of transmitting motion and force, and also plays Safety protection effect and used to adjust the size of discharge. Because the thrust plate is installed in the lower part of the machine body, it is not easy to maintain, so the plate head and plate seat are the * easy to wear parts. The worn plate head and plate seat can be corrected by post-surfacing processing, spraying, brush plating, etc. When the thrust plate is broken, because of the functional effect, it is generally not corrected, and a new thrust plate should be replaced. However, the combined thrust plate can be removed and used continuously. The common damage forms of the movable jaw of the compound pendulum jaw crusher are: inner hole wear, spring pull rod hook broken, partial crack or overload cracking.     2. Repair of the mobile jaw of jaw crusher. Because the movable jaw is heavy and messy, it is one of the main components of the jaw crusher. Therefore, it be corrected by various methods. For small and medium-sized jaw crushers, there are two types of movable jaw internal assembly: one is a babbitt alloy sleeve with an inner hole, and the other is a rolling bearing with an inner hole. After the babbitt alloy sleeve is worn out, just replace the spare sleeve, and then modify or cast the replaced babbitt alloy sleeve from the beginning. The inner hole of the rolling bearing of the device is often encountered because of fretting wear, poor device, or long-term operation, the outer ring of the rolling bearing is loose, and the inner hole is worn. The correction methods include inner hole repair welding and inner hole inserting. Inner hole repair welding, that is, manual arc welding is used for surfacing one layer on both ends of the inner hole, and then the hole is reamed from the beginning. The hole reaming skills are required to be performed according to the design cooperation accuracy. The method of inserting the inner hole to correct the movable jaw, although the process is more complicated, it is very suitable for the movable jaw of cast iron.
    Reminder: When the jaw crusher is in use, because there are many internal wear parts, it is necessary to check the wear condition of each part frequently. Timely repair can prolong the service life of the equipment, recover the equipment function, and make the production proceed smoothly.
