Cone crushers are widely used in the mining and aggregates industries to reduce the size of blasted rock by compressing the material between cone crusher mantle and bowl liner.
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.
And the bowl liner which is also known as cone crusher concave, is the sacrificial wear liner which sets inside the upper frame for protecting the upper accessories of the cone crusher.
Cone crusher mantle and bowl liner are engineered to improve efficiency and reduce costs by extending wear life and minimizing downtime.
