MANTLE & BOWL LINER

Contact us
What are cone crusher mantles & bowl liners?

Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock by compressing the material between two manganese liners: the mantle and the bowl liner (concave ring).

The mantle covers the cone head to protect it from wear; we can see it as a sacrificial wear liner that sits on the cone head.

The bowl liner, also known as concave, is the sacrificial wear liner that sets inside the upper frame to protect the upper accessories of the cone crusher.

GTEK cone crusher mantle and bowl liner are engineered to improve efficiency and reduce costs by extending wear life and minimizing downtime.

Metallurgical Options

The mantle and concave are often made of austenitic manganese steel, a material well known for its work hardening capability. GTEK offers a range of standard and premium alloys to choose from that meet your specific needs. These alloys form the base for our wear liners, and all are made from manganese steel - a mixtrue manganese, carbon and chromium.

We offer cone liners in 13%, 18%, and 22% grades of manganese, with chromium ranging from 1.5% to 2%. Alloying elements can be added upon requirements, such as Mo (molybdenum) or wear-resistant inserts.

We keep a chemistry inspection report for each order, even each cone, for quality tracking purposes.

Additional Alloys

In high-manganese steels, molybdenum refines the microstructure, strengthens the alloy, and significantly improves resistance to abrasive wear. Its addition is especially valuable in thick castings.

Standard high-manganese steel excels in high-impact situations where it work-hardens to create a tough, wear-resistant surface. However, its effectiveness diminishes under conditions of low-to-moderate impact or when the crushing process involves fine, abrasive materials, which can wear down the liner before sufficient work-hardening occurs. TiC inserts address this weakness.
