Jaw Crusher Frame Cracking

During the welding of the jaw crusher frame, if the welding process is slightly out of place, defects will appear and the jaw crusher equipment will vibrate during the process of crushing the ore, which will cause the frame to crack over time. The cracking of the frame is not easily detected at the beginning, so the frame of the jaw crusher is often cracked without any signs. About the causes and solutions of jaw crusher frame cracking, we briefly analyze for you to prevent the frame from breaking in production.

1. Frame fracture is related to the jaw crusher itself: when producing jaw crusher equipment, the welding and casting process is not in place can cause the cracking of the frame. This phenomenon should be repaired by welding, and if the cracking is more serious, the frame should be replaced.

2. The liner plate of the jaw breaker is not made of suitable material, the jaw crusher can not withstand the huge impact force in operation, when the impact force is too large the jaw crusher can not buffer and self-protection, which leads to damage or fracture of the frame. At this time, the elbow plate should be replaced to ensure the coordination of the elbow plate and the frame.

3. When the jaw crusher is installed, the jaw plate is not fixed firmly enough, and the jaw plate is loosened due to the vibration generated by the jaw crusher equipment during long time operation, which can lead to damage of the frame due to serious impact. In this case, the frame should be repaired or replaced and the bolts of the jaw plate should be fixed.

4. When the jaw crusher is installed, the bolts of the frame are not fastened well and the bolts are loosened due to vibration, in this case, the bolts of the frame should be fastened.

5. The eccentric shaft of the jaw crusher is damaged or the expansion sleeve is loose, which causes the misalignment of the counterweight of the fly groove wheel. In this case, the eccentric shaft should be replaced or the expansion sleeve should be tightened.

The above are the reasons and solutions for the loosening of the jaw crusher frame. We should conduct regular inspection when using the jaw crusher equipment, and if any abnormalities are found, we should solve them in time to avoid losing a lot of money due to the smallness.
