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.

Working principle
The motor drives the eccentric sleeve to rotate, and the moving cone crusher liner (mantle) rotates and swings under the force of the eccentric sleeve. The high manganese steel crusher liner on the moving cone sometimes approaches and sometimes leaves the concave fixed on the adjustment sleeve, so that the material in the crushing chamber is continuously impacted, squeezed and bent and crushed.

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
- Model making: According to the design drawings, use wood, metal or plastic and other materials to make a model with the same shape and size as the crushing wall for modeling in the casting process.
- Modeling and core making: Fill the modeling materials such as molding sand around the model, take out the model after compaction, and form a casting cavity. For the crushing wall with complex structure, it is also necessary to make a core to form an internal cavity or hole.
- Melting and pouring: Put the high manganese steel raw materials into an electric furnace or other melting furnace for melting. After reaching the appropriate temperature and composition, pour the molten steel into the casting cavity, and cool and solidify to form a high manganese steel crushing wall blank.
- Heat treatment: The crushing wall blank after casting is subjected to heat treatment processes such as water toughening to eliminate casting stress and improve the strength, toughness and wear resistance of the material.
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.
