How to replace cone crusher wear parts?

Cone crushers are widely used in mining, quarrying, and aggregate production for reducing large rocks into smaller, uniform sizes. However, due to continuous crushing operations under heavy load and abrasive conditions, critical wear parts such as mantles, concaves, liners, and bowl liners experience gradual wear. Timely replacement of cone crusher wear parts is essential not only to maintain high crushing efficiency and consistent product size, but also to extend the overall lifespan of the equipment and reduce unplanned downtime.

Replacing a cone crusher’s wear parts, primarily the mantle and concave (bowl liner), is a multi-step process that requires careful attention to safety and manufacturer guidelines. These parts are typically made of high-manganese steel due to its durability and wear resistance.

Safety First!

Lock Out/Tag Out: Before starting any maintenance, always ensure the crusher’s power is disconnected and locked out to prevent accidental startup.

Personal Protective Equipment (PPE): Wear appropriate PPE, including hard hat, safety glasses, gloves, and steel-toed boots.

Read the Manual: Always consult your specific crusher’s operation and maintenance manual for detailed instructions and safety procedures.

Steps to Replace Wear Parts

1. Preparation and Disassembly:

Clear the Crusher: Ensure the crusher is empty of any material.

Remove the Top Shell (if applicable): Depending on your crusher model, you might need to remove the top shell to access some wear parts. This usually involves unbolting and carefully lifting it with appropriate lifting equipment.

Remove the Bowl (Concaves/Mantle):

Loosen Bowl Nuts: Use a specialized tool or impact wrench to loosen the large nuts that hold the bowl liner (concaves) in place.

Lift the Bowl: Use a crane or other lifting device to carefully lift and remove the bowl.

Remove Old Concaves: Once the bowl is off, the old concaves can be unbolted or pried out. They are often backed with epoxy or zinc, which will need to be broken away.

2. Replacing the Mantle:

The mantle is the wear part on the cone head.
