5 Key Applications for Wear-Resistant Materials in Mining and Aggregate

Mining and aggregate operations are some of the most punishing environments of any industry. From rock crushing to slurry movement, equipment is subject to constant impact, abrasion, and corrosion—all of which take a heavy toll on unprotected surfaces.

In these conditions, wear-resistant materials make all the difference in helping you maintain safety, uptime, and profitability. At Copps Industries, we formulate high-performance epoxy systems designed specifically to meet harsh conditions and tough challenges. Our solutions help you extend equipment life, reduce downtime, and lower your total cost of ownership.

Here are five of the most common—and critical—applications where our materials make a difference:

1. Crushers: Liner Backing for Maximum Protection

The Challenge: Crushers are the workhorses of many mining and aggregate operations, facing extreme forces as they break down large materials. Impact, compression, and vibration lead to liner wear, misalignment, and structural damage.

The Solution: Copps’ crusher backing compounds fill cavities behind wear parts and support liner surfaces, reducing movement and minimizing the effects of vibration and impact. Our systems help protect the integrity of crushers, reducing maintenance and unplanned shutdowns.

2. Chutes and Hoppers: Shielding Against Abrasion

The Challenge: Chutes and hoppers experience constant material flow, often at high velocities. Over time, this flow erodes surfaces and creates pits or grooves that lead to equipment failure.

The Solution: Copps offers epoxy wear liners that provide a durable, non-metallic barrier in high-impact zones. These materials are ideal for extending the life of steel and concrete components and can be applied by trowel or pour, depending on site needs.

3. Conveyors and Transfer Points: Keeping Material Moving

The Challenge: Conveyors and transfer points are under constant friction and impact, making them vulnerable to wear along skirting, beds, and loading zones. Unprotected components result in material loss, misalignment, and premature equipment failure.

The Solution: Our wear-resistant epoxy coatings protect these high-friction areas, reducing maintenance needs and preventing breakdowns. By improving surface integrity, we ensure smooth, reliable material transport throughout your operation.

4. Pumps and Cyclones: Combating Erosion in Slurry Systems

The Challenge: In systems handling abrasive slurries, high-velocity flows rapidly erode internal surfaces, compromising performance and increasing maintenance frequency.

The Solution: Copps’ repair and rebuild compounds are formulated for harsh, wet environments. They restore damaged surfaces and add a protective epoxy layer that resists erosion and chemical attack and extends service life.

5. Screening and Sorting Equipment: Preserving Efficiency

The Challenge: Screening and sorting machines are exposed to intense vibration and impact, which cause component failure over time.

The Solution: Copps’ grouts and coatings reinforce screen housings, frame joints, and mounting points. These products help prevent structural degradation, ensuring your systems remain efficient and accurate.

Innovation from Copps Industries 

At Copps Industries, we develop purpose-built solutions that thrive under pressure. Our full line of crusher backing compounds delivers the performance you need in the most demanding environments:

• Cold cure crusher backing performs reliably in low-temperature environments (25°F to 60°F / -4°C to 16°C).
• Non-corrosive bushing lock is the industry standard for eccentric assemblies, preventing bushing rotation and extending equipment life.

Key Advantages of Copps Wear-Resistant Epoxies:

• Extended machinery life through better impact and vibration resistance
• Exceptional compressive strength and a broader array of service temperatures
• Low shrinkage to prevent voids and misalignments
• Elimination of wear liner gaps for better impact resistance
• Enhanced safety (no molten metals required, unlike traditional methods)
• ISO 9001-certified quality control for consistent performance

Extend Your Equipment Life, Improve Your ROI

In high-impact industries like mining and aggregate, wear-resistant materials aren’t optional—they’re essential. The right protection can mean the difference between unexpected downtime and uninterrupted production.

Copps Industries delivers proven solutions engineered to match the intensity of your operation.
