How to Extend the Life of your Cone Crusher

Cone crushers are the workhorses of many quarry and mining operations. They handle tough materials, deliver consistent product sizes, and keep production moving,  but only if they’re properly maintained. A cone crusher that’s neglected will wear out faster, break down more often, and cost more to operate over its lifetime.

At Marion Machine, we’ve rebuilt countless cone crushers, and we know the difference regular care and maintenance can make. Here’s our guide to keeping your cone crusher running longer and stronger.

1. Follow a Consistent Maintenance Schedule

Routine maintenance is the single most important factor in extending your cone crusher’s lifespan. This includes:

• Checking oil levels and quality regularly

• Inspecting liners and wear parts for damage

• Cleaning dust and debris from key components

• Monitoring for unusual noises or vibrations

Pro tip: Stick to the manufacturer’s maintenance schedule, but don’t be afraid to inspect more often if you’re running in especially abrasive conditions.

2. Keep Lubrication Clean and Adequate

Lubrication reduces friction between moving parts, helping prevent premature wear. Contaminated or insufficient lubrication can cause serious,  and costly damage.

• Use the correct lubricant specified for your crusher model

• Replace oil and filters at recommended intervals

• Check for leaks and address them immediately

At Marion Machine, we see more bearing failures caused by poor lubrication than almost any other issue.

3. Monitor and Replace Wear Parts Before They Fail

Worn liners, mantles, and other wear components don’t just hurt performance, they can also cause damage to the crusher’s frame and head.

• Keep a wear log to track part usage

• Replace parts before they reach critical wear limits

• Use high-quality, OEM or expertly machined replacement parts

4. Avoid Overloading the Crusher

Pushing your cone crusher beyond its capacity can lead to accelerated wear and even catastrophic failure.

• Feed material should be well-graded and within the crusher’s design limits

• Avoid letting oversized material enter the chamber

• Use a consistent feed rate to prevent pressure spikes

5. Partner with a Trusted Repair & Rebuild Facility

Even with the best in-house maintenance, cone crushers will eventually need professional attention.
A qualified service partner can:

• Conduct detailed inspections and measurements

• Repair or rebuild critical components

• Restore the crusher to OEM specifications
