When a critical piece of equipment goes down, every hour counts.

Recently, we got the call: a long-running HP300 cone crusher on site had finally reached the end of its road. Worn down and no longer reliable, production was at a standstill. Within hours, our team jumped into action.

We had an expertly rebuilt HP300 cone crusher in our prepped and in stock. This unit wasn’t just rebuilt, it was precision-inspected, restored with OEM components, and ready for performance in the field. Our team carefully prepared it for transport and had it shipped out in record time.

When it arrived on site, it was go-time. The installation went smoothly, and the customer was back up and running just five days after that first breakdown call.

Meanwhile, the original, tired HP300 was shipped back to our shop. It’s now undergoing a comprehensive teardown and world-class rebuild to bring it back to like-new condition, ready to serve the next operation in need.

So how do you know when it’s time to rebuild instead of replace?

Here are five signs it might be time to call in the experts—and why Mellott’s Rebuild Program could be the smarter move for your operation.

1. Your Crusher Still Has a Solid Frame

If the main frame or structure of your cone, jaw, or impact crusher is still in good condition, a rebuild is often the most efficient solution. Much of a crusher’s lifespan lies in its core components, and if those are still structurally sound, you’re sitting on an asset worth revitalizing.

Good Candidate: No major cracks, warping, or corrosion
Risk of Waiting: Frame damage is often irreversible. Rebuild before problems spread.

2. Maintenance Downtime Is Increasing

If your machine is breaking down more frequently or requiring more intensive maintenance, it may be time to overhaul the internal components. Worn bearings, bushings, or worn-out liners can cause performance to plummet, putting strain on the rest of your equipment.

Good Candidate: Frequent repairs, but nothing catastrophic
Pro Tip: A well-timed rebuild can often double the lifespan of certain internal parts.

3. OEM Lead Times Are Slowing Your Production

In today’s market, waiting 6–12 months for a new crusher can mean missed deadlines, delayed contracts, and frustrated customers. Rebuilding your existing machine through Mellott’s rebuild program can get you back up and running much faster, and often with upgraded performance and reliability.

Avoid: Long shipping delays, tariff complications, and unpredictable costs
In Stock: Mellott has rebuilt HP and classic cones available now—ready to ship.

4. You’re Looking to Upgrade Performance Without a New Purchase

Rebuilding doesn’t mean resetting your crusher to its original specs. It’s an opportunity to upgrade components, incorporate automation, and optimize wear parts for your exact application.

Options Include:

• New liners for extended wear life

• Modern hydraulic systems

• Improved feed cone liners (ask us about rubber feed cone upgrades!)

5. Your Crusher No Longer Meets Production Targets

Throughput and efficiency tend to suffer when internal wear goes unchecked. If you’re struggling to hit your tonnage goals, but the crusher still has potential, a rebuild might restore the power you need—without the cost of starting over.

Success Story: Customers often report 20–40% improvements in performance after a full rebuild.

Don’t Wait for a Catastrophic Failure

A proactive rebuild can save you from a costly emergency—and give your crusher a second life. If your equipment is showing any of the signs above, it’s time to explore your options.
