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.
