Analysis of the reasons why the copper sleeve of cone crusher is burned out

1. Poor lubrication: The lubrication system is a key part of the normal operation of the cone crusher. If there is a failure in the lubrication system, such as insufficient lubricating oil, oil pump failure or improper lubricating oil selection, the copper sleeve may be burned due to frictional heat.

2. Improper shape of the lining cavity: If the design of the lining cavity is unreasonable, it may cause the copper sleeve to receive uneven force during the crushing process, which may lead to local overheating and burning.

3. Poor lining quality: If the quality of the lining material is not up to standard, such as insufficient hardness, poor wear resistance, etc., it may wear prematurely during the crushing process, thereby increasing the load on the copper sleeve and causing burnout.

4. The tight side discharge opening is too small: If the tight side discharge opening is set too small, it may cause too much material to accumulate in the crushing cavity, increase the friction and load of the copper sleeve, and cause burnout.

5. Feeding segregation: If the feeding is uneven or segregated, it may lead to uneven distribution of materials in the crushing cavity, which may cause local overheating and burning of the copper sleeve.

6. Incorrect rotation direction: If the rotation direction of the cone crusher is set incorrectly, the copper sleeve may be subject to abnormal force during the crushing process, causing burnout.

7. Improper current regulation: If the current regulation system of the crusher is improperly set, such as the current is too large or too small, it may cause the crusher to operate under abnormal working conditions, which may cause the copper sleeve to burn.
