Jaw crusher is one of the most commonly used crushing equipment in industrial and mining production. In the production operation, it is often encountered some problems. Now the jaw crusher common troubleshooting methods are as follows:
When the jaw crusher run or non-crushing into the crushing chamber, it is easy to cause the brackets to break, this time should replace the brackets and control the feed size, to prevent non-crushing into the crushing chamber, and try to avoid the host super Load work. If the elbow pad has been worn, replace it with the brackets, and select the qualified brackets to install correctly.
2. The bearing temperature is too high
Under normal operating conditions, the bearing temperature should not exceed 35 ℃, the maximum temperature shall not exceed 70 ℃. If the temperature is too high, should be added to the amount of grease, with a gasket to adjust the degree of tightness of the bearing to repair the bearing tile or replace the bearing, because this situation may be due to the bearing gap is not suitable for poor bearing contact or bearing damage caused.
3. The host suddenly shut down
This phenomenon commonly known as "boring car". In this case, you should first check the discharge port is blocked, to ensure that the material flow; followed by the drive wheel to drive the V-belt is too loose, should be tightened or replaced V-belt; final check eccentric shaft tightening bushing Loose caused by eccentric shaft stuck, should be re-installed or replace the tightening bushing.
4. Adjust the seat
Adjust the seat fixing bolt loose, need to tighten the adjustment bolt; adjust the seat has a serious casting defects or welding defects, need to replace the adjustment seat and brackets, elbow plate pad (Pang Bo Heavy Industries reminder: the best replacement of the original factory assembly liner , Liner pad, do not buy or modify their own).
5. Product size becomes thicker
Jaw crusher tooth plate when the lower part of the serious wear and tear, the product will become thicker. In this case, the tooth plate U-turn or adjust the discharge port will make this situation has been significantly improved.
6. Production does not meet the production standards
To ensure that the workplace voltage in line with the requirements of the host overload requirements, adjust the jaw crusher discharge port, so that compliance with the provisions of the instructions. Check the tooth plate pitch size, if not meet the standard need to replace the jaw plate, adjust the relative position of the jaw and moving jaw, to ensure that the tooth after the tooth root, fixed compression, to prevent displacement. The following are the same as the "
In the jaw crusher long-term use of the process, the failure is inevitable, to understand some of the symptoms and troubleshooting methods, so that prepared, to ensure the smooth progress of our work.
