How to reduce the wear of cone crusher lining?

The wear of cone crusher lining is a common and important problem. Reducing its wear can not only increase the service life of the equipment, but also reduce production costs. The following are some effective ways to reduce the wear of cone crusher lining:

Choose the right lining material
High manganese steel lining: It has high wear resistance and impact resistance, and is suitable for processing materials with higher hardness, such as limestone, granite, etc.
Cast iron lining: It has high wear resistance and impact resistance, and the cost is relatively low, which is suitable for the use of some small and medium-sized crushers.
Composite lining: It is composed of a variety of materials, has high wear resistance and impact resistance, light structure, and can improve the operation efficiency of the crusher.

Optimize lining design
Reasonable thickness: The thickness design of the lining should be adjusted according to the actual working conditions of the crusher. Too thin thickness is prone to premature wear, and too thick thickness may affect the crushing efficiency.
Optimize shape: It is designed as a replaceable modular structure, which is convenient for partial replacement when the lining is severely worn, avoiding the waste of resources caused by overall replacement.
Improve liner installation and maintenance
Reduce looseness: By padding soft metal gaskets between the liner and the cone and tightening them with bolts, the phenomenon of breakage or wear caused by loose liner can be reduced.
Improve force: Plastic precipitation, such as lead plate, aluminum plate, etc., is placed between the liner and the cone to ensure the close combination of the liner and the cone, so that the force at each point of the liner is uniform.
Regular inspection: Regularly inspect and maintain the cone crusher to detect and deal with wear problems in a timely manner. For example, by regularly checking the wear of the liner, replace the liner with severe wear as soon as possible.

Optimize operating conditions
Reasonable load: Overload or underload operation will cause excessive wear of the liner. The operating load should be reasonably adjusted according to the design load range of the crusher.
Uniform feeding: Uneven feeding will cause local wear of the liner to increase, so the material should be fed evenly to avoid material accumulation or blockage.
Control the feed size: Ensure that the material put into the equipment meets the crushing requirements. It is strictly forbidden to enter the crushing chamber with excessive hardness, high moisture or other non-crushing materials.
Other preventive measures
Install iron remover: Install a reasonable iron remover at the head of the feeding belt to effectively remove the iron blocks entering the crushing chamber and prevent the liner from breaking due to the high hardness of the iron blocks.
Lubrication and cooling: Lubricate the equipment well to reduce the phenomenon of excessive temperature rise of the equipment, thereby reducing the plastic deformation of the liner.
Determine the liner replacement cycle: Determine the best replacement cycle based on the use of the liner to avoid affecting the normal operation of the equipment due to excessive wear of the liner.
In summary, by selecting the appropriate liner material, optimizing the liner design, improving the liner installation and maintenance, optimizing the operating conditions and taking other preventive measures, the wear of the cone crusher liner can be effectively reduced, and the service life and production efficiency of the equipment can be improved.
