Mantle and bowl liner are matched high manganese steel wear castings for cone crushers, used in secondary and tertiary crushing. Mantle rotates while bowl liner stays stationary to squeeze hard rock. Widely used in quarry, sand production and mineral crushing circuits. Custom casting for different cone crusher models available.
Cone Crusher Mantle & Bowl Liner
High Manganese Steel Cast Wear Parts for Cone Crusher
Product Overview
Mantle and bowl liner are a matched pair of core wear castings inside cone crushers, widely used for secondary and tertiary hard rock crushing. The mantle is mounted on the rotating main shaft cone, while bowl liner is fixed on the upper bowl assembly. Rocks are squeezed, crushed and ground between rotating mantle and stationary bowl liner.
Made of high manganese steel, these liners continuously wear down during crushing operation and require regular replacement. They are critical consumable spare parts for aggregate quarries, sand plants and mineral processing crushing lines.
Disclaimer: All products are compatible replacement wear castings, not genuine OEM original brand parts.
Working Principle & Core Function
- Rock Squeezing & Comminution: Mantle rotates gyrationally, material is compressed and crushed between mantle and bowl liner.
- Continuous Wear Protection: The liners take all impact and abrasive wear, protecting the cone crusher main body and frame.
- Control Product Gradation: Mantle and bowl liner profile defines output particle size and crushed stone shape.
- Easy Replacement: Modular casting design for on-site change-out, reducing crusher downtime.
