Mellott continually partners with customers to improve crushing efficiency, extend wear life, and lower operating costs. To quantify the real-world performance of , Mellott conducted comparative liner scans on both Metso Long Life (LL) liners and a competitor liner set (ME) installed in the same HP400 crusher configuration.

Both were evaluated using 3D scanning technology to capture wear profiles, remaining material, and operational performance.

Metso HP400 Long Life Liners – Inspection Details

• Crusher Model: Metso HP400
• Chamber Type: SH M
• Bowl Liner: MM2039548
• Mantle: MM2039547

A used set of Metso Long Life liners was scanned to assess wear distribution, liner utilization, and remaining service life.

Competitor HP400 Liners – Inspection Details (ME)

A used set of competitor liners (ME) was also scanned for direct comparison.

• Crusher Model: HP400
• Chamber Type: SH M
• Bowl Liner: 1048300035 (Short Head Medium Bowl Liner)
• Mantle: 7055308387* (STD Fine Mantle)

The competitor bowl liner was identified as a Short Head Medium profile, while the mantle utilized a Standard Fine profile.

are engineered with uptime in mind. Their straightforward design, predictable wear patterns, and service-friendly features make them a smart choice for operations that value efficiency, safety, and long-term performance.

A Simple Design That Delivers Big Results

One of the standout advantages of the Metso GP cone crusher is its mechanically simple, yet highly effective design. Unlike more complex systems that rely on multiple variables, GP cones utilize a fixed eccentric throw, reducing the number of adjustments required during operation.

This simplicity translates directly into:

• Fewer mechanical complications

• Easier troubleshooting

• More predictable crusher behavior

For maintenance teams, fewer variables mean less guesswork and more confidence when servicing the machine.

Faster, Safer Maintenance Procedures

Metso designed GP cone crushers with serviceability as a priority. Routine maintenance tasks, including liner changes,  are streamlined to minimize downtime and improve safety.

Maintenance-friendly features include:

• Easy access to internal components

• Straightforward liner replacement procedures

• Reduced need for specialized tools or extended shutdowns

These design elements allow crews to complete maintenance efficiently, helping plants return to production faster while maintaining a safer work environment.

Predictable Wear for Better Planning

Unpredictable wear is one of the biggest challenges in crushing operations. The Metso GP cone crusher’s consistent crushing action results in uniform liner wear, making it easier to plan maintenance intervals and manage wear part inventory.

Benefits of predictable wear include:

• Improved liner utilization

• Reduced emergency shutdowns

• More accurate maintenance scheduling

This level of consistency helps operations move from reactive maintenance to a more proactive, planned approach.

High Availability in Demanding Applications

Whether used in secondary, tertiary, or quaternary applications, GP cone crushers are built to perform in continuous, high-demand environments. Their rugged construction and dependable operation help ensure high availability even under tough conditions.

For producers running tight schedules or high-volume plants, this reliability can make a measurable difference in overall productivity and cost per ton.

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.

Why Choose Mellott for your Rebuild?

Rebuilding a crusher isn’t just a mechanical process, it’s a strategic investment in your plant’s future. At Mellott, we offer:

• Factory-trained technicians

• ready to ship

• Quick turnarounds with precision quality

• Customized upgrades to improve performance

• Lifetime support for your rebuilt unit

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.

Contact Mellott today to discuss whether your crusher is a candidate for a rebuild.

But what’s the real cost of downtime, and what can you do to prevent it?

The Hidden Price of a Silent Crusher

When your operation comes to a halt, you’re not just losing tons per hour. You’re also absorbing:

• Labor Costs – Your crew is still on the clock, even if the machine isn’t.

• Missed Production Goals – Lost hours today can set back delivery schedules, customer commitments, and profitability.

• Emergency Repair Premiums – Last-minute fixes are often more expensive than planned maintenance.

• Reputational Damage – Reliability matters. Chronic downtime can hurt customer confidence and contract renewal prospects.

• Parts Delays – If a needed part isn’t in stock, you could be stuck for days waiting on delivery.

Even a few hours of unexpected downtime can translate to thousands—or tens of thousands—of dollars in losses.

The Mellott Solution:  Prevent, Not Just React

At Mellott, we believe proactive service is the best insurance policy against downtime. Here’s how we help customers stay ahead of the curve:
