Introducing the Diamond Edge™ Conveyor Belt

Jul 31, 2025 | potash news

Built to go the distance in potash mining

In the demanding world of underground potash mining, equipment failure isn’t just costly—it’s dangerous. That’s why Fenner Dunlop developed the Diamond Edge™, a revolutionary PVC conveyor belt engineered specifically for the extreme conditions found on extensible conveyors in Canada’s potash mining operations. With a proven track record of outperforming competitor belts by up to four-times in lifespan, Diamond Edge is the trusted choice for operations that can’t afford to compromise on safety, reliability, or performance.

Purpose-built for potash mining

The Diamond Edge™ belt wasn’t created in a lab—it was forged in the real-world challenges of underground potash mines. Designed for extensible conveyor systems, which are prone to uneven structure and high-impact loads, this belt delivers unmatched durability and longevity where it matters most. By focusing on the specific needs of Canadian potash operations, we’ve built a product that excels under conditions that typically cause premature failure in traditional belts.

Revolutionary edge design for superior wear resistance

Edge wear and stranding are leading causes of belt failure in harsh mining environments. The Diamond Edge™ belt tackles this issue head-on with a unique carcass design that incorporates a specialized fabric configuration in the belt edges. This design significantly reduces edge wear and minimizes stranding, allowing the belt to maintain its full width and structural integrity for a far longer period.

Result: Less edge degradation, fewer unscheduled stoppages, and extended belt life—up to four times longer than standard belts used in similar applications.

Engineered for strength and stability

Durability isn’t just about thicker covers—it’s about smarter construction. The Diamond Edge™ features:

  • Increased internal and cover adhesion
    Prevents delamination and improves resistance to point-of-trough failures.
  • Enhanced lateral stiffness
    Reduces belt deformation under load, increasing tracking stability and further preventing structural failure.
  • Increased cover hardness
    Improves resistance to abrasion and material penetration, a major issue in potash handling.

Unmatched joint performance

When your joints fail, your entire operation suffers. That’s why we designed the Diamond Edge™ to deliver an approximate doubling of dynamic fastener holding results compared to conventional belts. This ensures longer-lasting joints, fewer joint replacements, and reduced maintenance intervals—delivering measurable improvements in uptime and productivity.

Lightweight construction, heavyweight performance

Despite its rugged design, the Diamond Edge™ is lighter than an 800 PIW extensible belt. This translates into lower energy consumption, easier handling during installation and maintenance, and less strain on your conveyor system—without sacrificing strength or performance.

Real-world benefits that matter

The bottom line is simple: fewer belt changes, less downtime, lower cost per tonne, and improved operational safety. With fewer roll movements and maintenance interventions underground, your crews can focus on production instead of repair.

And in an industry where every hour counts and every ton matters, the Diamond Edge™ belt doesn’t just last longer—it delivers more value over its entire lifecycle.

Tested. Trusted. Proven.

The Diamond Edge™ isn’t just another belt—it’s a field-proven solution that has consistently outperformed competitors in side-by-side trials. In one case study, it lasted four-times longer than the next-best competitor in identical conditions, significantly reducing both direct and indirect operational costs.

Experience the edge

When it comes to potash mining, you need a belt that’s as tough and reliable as your crew. Choose Diamond Edge™—the belt designed to meet the demands of Canada’s most challenging underground operations.
