How to reduce the wear of the cone crusher liner?

Cone crusher is a commonly used secondary crushing equipment, which is good at crushing high-hardness ores, has good wear resistance and low operating costs. The liner is one of the vulnerable parts in the production of cone crusher, so how to reduce the wear of the cone crusher liner to extend its replacement cycle and reduce production costs.
 

Cone crusher

1. Reduce the loosening of the liner. The loosening of the liner will cause relative movement between the liner and the cone body, which will increase the wear. Therefore, soft metal gaskets can be placed between the liner and the cone, and tightened with bolts to ensure the flushness between the two, reducing the breakage or wear caused by loose liner.

2. Improve the stress state of the cone crusher liner. In order to make the liner evenly stressed at all points, plastic precipitation is often placed between the liner and the cone, such as lead plate, aluminum plate, zinc alloy plate, low-carbon steel plate or cement mortar, to ensure the close combination of the liner and the cone.

3. Control the feed particle size. During the operation of the cone crusher, it should be noted that the materials put into the equipment must meet the crushing requirements. It is strictly forbidden to enter the crushing chamber with excessive hardness, high moisture or other non-crushing materials, otherwise it will cause the cone crusher to jam and the liner to wear seriously.

4. Feed evenly. If the feed amount of the cone crusher is not adjusted in time, the ore will directly rub and collide with the liner, which will increase the wear of the liner. Therefore, it is necessary to ensure that the ore is evenly fed in the middle of the distribution plate, and the material cannot directly act on the liner to reduce the wear of the liner.

5. It is forbidden to overload the equipment. If the cone crusher works overloaded for a long time, the liner will be in an overloaded state for a long time. Therefore, the equipment should be prevented from working overloaded for a long time, the surface stress of the liner should be reduced, and the appropriate matching clearance should be selected to reduce the fatigue wear of the liner.

6. Prevent the equipment from overheating. If the working temperature of the cone crusher is high, it is easy for the liner to undergo plastic deformation under the impact and grinding of the material. Therefore, the equipment should be lubricated well to reduce the phenomenon of excessive temperature rise of the equipment and reduce the plastic deformation of the lining.
