Mining Machine Parts Bowl Liner Cone Crusher Rolling Wall

Material: High Manganese Steel (Mn13, Mn18), Alloy Steel (Cr-Mo-Ni), Customizable

Constructed from premium-grade high manganese steel, this rolling wall is built to withstand the extreme pressures and abrasion encountered in crushing operations. The high manganese steel material offers remarkable toughness and work-hardening capabilities: as materials are crushed between the rolling wall and the mantle, the constant impact and compression cause the surface of the rolling wall to harden significantly, forming a robust wear-resistant layer. This ensures long-lasting durability, even when processing hard and abrasive materials like granite, ore, and gravel.

A bowl liner is a vital wear part of cone crushers. It is specifically manufactured to fit the cone crusher’s mantle (rotating cone) for crushing ore, rock and mineral materials in the mining industry. It is part of the cone crusher “crushing chamber” and offers a fixed concave surface for the rotating mantle to be held against to exert high compressive force to reduce large chunks of ore to smaller manageable particles.
China Customized Mining Machine Parts Crusher Spare Parts bowl liner
The rolling wall is made of premium high-manganese steel which can stand up to the extreme pressures and abrasion associated with crushing operations. The high manganese steel material has good toughness and work hardening properties, so that the crushed materials are continuously impacted and compressed between the rolling wall and the mantle, which hardens the rolling wall surface and forms a strong wear-resistant layer. This ensures a long service life even when machining hard and abrasive materials such as granite, ore and gravel.
​
The production method is based on the accuracy. Every rolling wall is built to precise dimensional specifications for an exact match with compatible styles of cone crusher. This tight fit also helps in smooth operation and the crushing chamber design is customized for uniform particle size distribution and improved overall crushing efficiency. Whether you’re mining, building or producing aggregate, our rolling wall gives you constant, reliable performance.
​
Our cone crusher rolling wall designed to reduce replacement frequency and maintenance time. It has better wear resistance for a longer service life which reduces maintenance costs and increases production. They are also very well built. High-intensity crushing means a safer working environment and a higher efficiency; you will experience less vibration and noise.

Key Design Features

  1. Concave Shape:

    Fits the convex shape of the mantle to form a tapered crushing chamber (adjustable gap for different output sizes).

  2. Compatibility of materials:

    • High Manganese Steel (Mn13, Mn18) Most common. Excellent toughness and work-hardening properties (the surface hardness increases under impact, up to 500+ HBW, the core remains ductile). This material is suitable for medium to hard ores.
    • Alloy Steel (Cr-Mo-Ni Reinforced) Better wear resistance for highly abrasive ores (e.g. quartz, sandstone). Contains chromium and molybdenum for greater hardness (≥50 HRC) and lower wear rate.
    • High-Chrome Cast Iron Very hard (≥60 HRC) but not as tough. For very abrasive, low-impact applications.

  3. Mounting Structure:

    Bolted or clamped to the crusher upper frame (adjustable to fine-tune the discharge gap).

  4. Ribs/Grooves:

    Some designs feature internal ribs for added structural strength or surface grooves to improve ore grip and crushing efficiency.
