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 Company, we understand the value of keeping your screens in top condition. That’s why we offer a comprehensive, free screen inspection designed to optimize your equipment and keep your operation running smoothly.

What’s Included in a Mellott Screen Inspection?

During a thorough inspection, our experienced technicians evaluate every critical component of your screen:

• Screen media condition – Worn or damaged reduces efficiency and can lead to product quality issues.

• Bearing temperature (drive & non-drive side) – Overheated bearings are a warning sign of lubrication problems or mechanical wear.

• Spring condition – Weak or broken springs impact vibration efficiency, affecting material separation.

• Lubrication – Properly lubricated components last longer and reduce the risk of mechanical failure.

• V-belts – Loose or worn belts can decrease performance and put extra strain on motors.

• Overall operation – Ensuring the screen operates as designed prevents small problems from becoming costly production interruptions.

The Value of an Optimized Screen

Investing a little time in a professional screen inspection can deliver big results:

• Maximized productivity – Well-maintained screens operate more efficiently, increasing throughput.

• Improved product quality – Even separation ensures consistent material sizing.

• Reduced downtime – Identifying potential issues before they cause failures keeps your operation moving.

• Extended equipment life – Regular maintenance prevents excessive wear and extends the lifespan of your screen components.

Don’t start the year with preventable equipment problems. A simple inspection today can save time, money, and headaches tomorrow.

Call Mellott today to schedule your free screen inspection and ensure your screens are ready to perform at their best. Let us help you start the new year on the right foot!

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.
