Replacing your cone crusher’s mantle and concave (bowl liner) is heavy, demanding work. But doing it correctly and safely is the only way to protect your crusher's main shaft, maintain your desired Closed-Side Setting (CSS), and keep your cost-per-ton in check. Whether you're installing OEM parts or upgrading to premium Future Green Machinery (FGM) wear parts, follow this field-tested guide to execute a safe, efficient change-out without the headaches.
Never cut corners before the heavy lifting begins.
Getting worn parts out is often the hardest part of the job, especially if they have seized.
A new liner is only as good as the surface it sits on.
Precision here prevents catastrophic failures later.
Don't just hit the start button and walk away.
Always swap both the mantle and concave at the same time. Mixing a worn liner with a new one alters the crushing profile, reducing capacity and ruining shape.
Never start crushing before the epoxy backing compound has 100% cured. You will crack the epoxy and completely void the liner's structural support.
If your throughput drops by 10%, or your remaining liner thickness dips below 1 inch (~2.5 cm), you are wasting energy and risking frame damage. Replace them immediately.
