Analysis on the Cause of Burning of Cone Crusher Copper Bushing

1. Poor lubrication

Poor lubrication is one of the main reasons for the burning of the copper sleeve of the cone crusher. During the working process, the copper sleeve and the bearing rub against each other. If the lubricating oil is insufficient or the oil quality is poor, the high heat in the friction process cannot be dissipated, causing the temperature of the copper sleeve to rise abnormally, and long-term overheating is easy to cause burning.
Solution: Check the quality and quantity of the lubricating oil regularly, replace the expired or overused lubricating oil in time, and lubricate within the correct working temperature range.
2. Harsh working environment
The use environment of cone crushers in mining, construction, etc. is usually harsh, such as humidity, high temperature, dust, etc. Long-term use in such an environment will cause damage to the parts of the machine. For the copper sleeve, dust and moisture will block the lubricating oil holes, affect the lubrication effect, thereby aggravating the friction and wear, and even causing the copper sleeve to overheat.
Solution: Try to keep the working environment clean and dry, clean and inspect the parts regularly, and adopt dust and waterproof measures to ensure the working effect.
3. Wear of parts
During the use of the cone crusher, the friction between the copper sleeve and the bearing and other parts will cause long-term wear. Wear will cause high heat on the friction surface. When the temperature exceeds a certain limit, the copper sleeve is prone to burnout.
Solution: Regularly check the wear status of parts, replace failed parts in time, and use high-quality parts materials to extend the service life of the machine.
In summary, the causes of cone crusher copper sleeve burnout may involve multiple aspects, and the solution also needs to start from multiple angles, including good lubrication, suitable working environment, high-quality parts and other aspects. Only in this way can the normal operation and efficiency improvement of the cone crusher be ensured.
