Mantle Liner

Functions of Mantle and Bowl Liner:

Crushing: The mantle and bowl liner form the primary crushing surfaces, compressing and breaking feed material into smaller particles.

Wear Resistance / Durability: Manufactured from exceptionally hard materials, these components withstand severe abrasion and impact from crushing hard rock and ore, ensuring extended service life.

Process Efficiency: Correctly selected and precisely fitted liners optimize the crushing chamber geometry, significantly enhancing crushing efficiency and consistent product sizing.

Materials Used for Mantle and Bowl Liner:

Mantles and bowl liners are forged from premium, wear-resistant alloys to endure the extreme operating conditions. Key materials include:

Manganese Steel: The industry standard, offering outstanding work-hardening capability, high impact strength, and superior abrasion resistance under heavy loads.

Chrome-Moly Steel: Used in high-stress applications for its enhanced hardness, toughness, and resistance to gouging and deformation.

Specialty Alloy Steels: Employed for specific requirements; these include martensitic white iron alloys (like Ni-Hard) for extreme abrasion resistance, or other proprietary alloys tailored for particular ore characteristics or operational demands.
