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.

At Mellott, we’ve seen both sides, and we’re here to tell you why OEM parts can improve performance, reliability, and long-term cost savings.

What Are OEM Parts?

OEM parts are made by the original manufacturer of your equipment, such as or , and are specifically engineered to meet factory specification. These parts are identical to what your machine came with new, ensuring seamless fit and performance.

By contrast, aftermarket parts are made by third-party companies and can vary widely in terms of material quality, design tolerances, and lifespan.

5 Reasons to Choose OEM Parts

1. Guaranteed Fit and Function

OEM parts are made for your exact machine model, which means installation is easier, faster, and more reliable. No modification. No guesswork. No performance compromise.

2. Longer Equipment Life

High-quality OEM components are engineered to work in harmony with the rest of your crusher, reducing excess wear and helping to prevent expensive failures.

3. Less Downtime

Poorly fitting or low-quality aftermarket parts can lead to unexpected failures. With OEM parts, your equipment stays up and running longer with fewer surprises.

4. Protected Warranties

Many equipment warranties require OEM parts to remain valid. Using aftermarket components could void your coverage—leading to expensive repairs not covered by the manufacturer.

5. Proven Quality

OEM parts are rigorously tested and backed by data. At Mellott, we stand behind OEM components because we’ve seen them deliver under pressure on job sites across the country.

When Aftermarket Might Make Sense

Not all aftermarket parts are created equal—some can be a good fit for non-critical components or temporary fixes. But in high-wear areas or mission-critical systems like cone liners, rotors, and bearings, the risk often outweighs the reward.

Partner with Mellott for OEM Confidence

At Mellott, we stock a of OEM crusher parts—from Metso, McLanahan, Eagle, and more ready to ship when you need them. Plus, our expert team can help you identify the right part and get it to your site fast.

At Mellott, we’ve worked with hundreds of operations to help extend the life of their equipment. Below is an overview of a  preventative maintenance checklist to help you stay ahead of wear, breakdowns, and costly repairs.

Daily Cone Crusher Maintenance Tasks

These daily checks should be part of every operator’s routine:

• Visual inspection of the crusher and surrounding area

  • Check for oil leaks, worn parts, or any debris buildup around the machine.

• Lubrication system check

  • Ensure oil levels are correct and free of contamination.

  • Verify that all grease points are receiving proper lubrication.

• Check hydraulic system pressure

  • Confirm that settings match manufacturer recommendations.

• Monitor and log operating temperatures

  • A spike in bearing or oil temperature can signal early-stage problems.

• Listen for unusual sounds

  • Grinding, popping, or knocking noises can indicate component wear or failure.

Weekly Maintenance Checklist

Once a week, spend more time on deeper inspection:

• Check and clean the oil cooler

  • Dirt and debris can clog cooling fins, reducing system efficiency.

• Inspect wear parts

  • Look at liners, mantle, and concave for signs of .

• Check belt tension and alignment

  • Misaligned or loose belts can reduce power transmission and damage the motor.

• Clean the dust sealing system

  • Ensure all seals are intact to prevent of internal components

Monthly and Quarterly Tasks

Longer-term maintenance keeps your crusher healthy year-round:

• Change out oil and filters (per manufacturer schedule)

  • Old or contaminated oil reduces component life dramatically.

• Check drive motors and gearboxes

  • Look for overheating, vibration, or unusual sounds.

• Examine structural components

  • Inspect frame welds, mounting bolts, and foundation for cracks or fatigue.

• Inspect tramp relief system

  • Make sure relief cylinders are responsive and properly pressurized.

Common Cone Crusher Maintenance Mistakes to Avoid

• Skipping inspections during peak season
  Downtime always costs more during high-demand periods.

• Waiting until failure to replace liners
  Worn liners reduce crushing efficiency and cause uneven wear on the machine.

• Ignoring warning signs
  Small anomalies—like temperature shifts or odd noises—can quickly escalate into major repairs.
