High Manganese Steel Cone Crusher Concave and Mantle - China Suppliers & Factory for Durable Wear Parts
Features
Super wear resistance
The hardness of our cone crusher liners is more than HRC68°. Under large impact or contact stress, the surface layer is rapidly hardened, and the hardening index is 5-7 times higher than other materials, which greatly improves wear resistance.
Good toughness
The tensile strength of our cone liner exceeds 1500MPa and the impact toughness of the matrix exceeds 119J/cm2. It has good plasticity and impact toughness, can withstand the strong impact force generated by the cone crusher when it is working, and is not prone to brittle fracture.
Long service life
More than twice that of conventional crusher liners, reducing your parts replacement time and improving crushing efficiency.

Other Cone Crushers
In addition to the equipment models listed above, there are many other cone crushers. We can provide high-performance crusher liners for your equipment. You only need to provide photos and nameplates of the equipment and part numbers of wear parts. Of course, it would be better if you can provide drawings.
Maintenance and Care
Regular inspection
Regularly stop the machine to check the wear of the crusher liners, observe whether the wear is uniform, whether there is severe local wear or cracks, etc.
Adjustment and installation
When installing the crusher lining, ensure that it is firmly installed and the gap between the concave and mantle is uniform and consistent.
Control materials
Strictly control the particle size of the material entering the crushing chamber to avoid excessively large or hard materials (especially metals) from entering the crushing chamber to prevent excessive wear or damage to the crusher lining.
Material Properties
Usually our crusher wear parts are based on Mn18Cr2, and we add our developed high-crystalline nano compounds (after more than 4 process treatments, they can be perfectly integrated into the base material). This makes the cast crusher wear parts have the following excellent characteristics: tensile strength greater than 1500MPa, impact resistance greater than 120J/cm2, and hardness greater than or equal to HRA85°.
Production Process
Quality Control
Chemical composition detection
The chemical composition of high manganese steel materials is strictly tested by means such as spectral analysis to ensure that the content of each element meets the standard requirements, such as manganese content is generally 10%-15%, and carbon content is 0.90%-1.50%.
Hardness test
Use a hardness tester to test the hardness of the crushing wall surface and key parts to ensure that the hardness value is within a reasonable range to meet the wear resistance requirements.
Flaw detection
Use ultrasonic flaw detection, magnetic particle flaw detection or radiographic flaw detection to detect whether there are cracks, pores, sand holes and other defects inside the crushing wall to ensure product quality.
