Conveyor Belt Cleaners Engineered to Exceed in Demanding Mining Environments
Patented Knife Tips and adaptive tensioning deliver 3–4× longer blade life, up to 99% carryback reduction, and measurable ROI in iron ore, coal, and bulk material operations.
Innovation Focus
While others follow industry standards, FM8 redefines them. Our proprietary tensioner technology represents the first major advancement in primary cleaner tensioner design in decades, delivering consistent blade-to-belt pressure that adapts to real-world conditions.
Performance Guarantee
Engineered for the harshest mining environments, FM8 scraper blades and tensioners maintain optimal cleaning efficiency from installation to replacement. Less carryback. Less maintenance. More production.
Australian Engineering. Global Standards
Designed and tested in Australia's most demanding bulk material handling operations, FM8 products meet ISO standards while solving the specific challenges of iron ore, coal, and mineral processing applications.
FM8- Engineered to Exceed. Patented to Perform.
FM8 holds patented technology across two critical conveyor cleaning innovations: our revolutionary Knife Tips scraper blade technology and our game-changing primary cleaner tensioner system. While competitors offer incremental improvements, FM8 delivers breakthrough performance.

Frequently Asked Questions
ABOUT FM8 & OUR TECHNOLOGY
-
FM8 is an Australian engineering company that designs conveyor belt cleaners around one idea: holding blade-to-belt pressure steady as the blade wears. Our Knife Tip scraper blades and the FM8 Tensioning System are the subject of international patent applications (International Patents Pending). The range includes FRAS-rated primary and secondary cleaners for underground coal. Because results depend on your conveyor, FM8 offers a Verified Validation Trial so you can measure blade life on your own site before you commit.
-
A knife tip is a narrow leading edge on the cleaner blade, commonly 2 to 5 mm wide, that concentrates the tensioner load into a small contact band at the belt. FM8 Knife Tips are available with a Tool Steel or Tungsten Carbide edge. Where a site wants the tip to conform to the belt quickly, a polyurethane overlay wears in first (rapid bed-in) and the durable core takes over from there. The technology is International Patents Pending.
-
Blade-to-belt pressure is force divided by contact area. Even when a conventional tensioner holds its force steady, the force at the belt roughly doubles over blade life as the blade shortens, so pressure drifts and crews wind on more tension. The FM8 Tensioning System pairs a constant pressure tensioner with FM8 constant pressure primary blades whose contact area grows as they wear, and it is engineered for constant pressure. It uses an electrically driven closed loop hydraulic circuit, so there are no compressed-air lines or regulators and no spring or air-bag tensioner to re-adjust. An engineered hard stop eliminates the possibility of pull-through. International Patents Pending.
-
FM8 products are engineered for mining, ports and terminals, and bulk materials handling, including coal, iron ore and hard rock duties. If your conveyor handles bulk material and carryback is a problem, send FM8 Engineering your belt and product details and we will tell you whether a blade is the constraint or whether the cause is upstream.
INSTALLATION & MAINTENANCE
-
FM8 Super XHD primary blades are interchangeable with all XHD blades and compatible with all removal tools, so changeouts run the way your crew already changes blades. The FM8 Tensioning System picks up the existing tensioner mounting holes on your current mainframe, so there is no new drilling into the chute or structure, and the work fits inside a conveyor isolation already taken for a blade change. Fit is confirmed for each installation.
-
The cylinder advances the blade continuously as it wears, so the setting does not need to be restored. That means zero mainframe resets across the full 45 degree wear arc, against two on a conventional tensioner. There are no compressed-air lines or regulators and no spring or air-bag tensioner to re-adjust. Your normal inspection routine for the cleaner still applies, and full automation with remote monitoring of blade health and remaining blade life is available as an option.
-
Plan changeouts from measured wear rather than a calendar interval. With the FM8 Conveyor Cleaner Health app, your technician photographs the blade in place, confirms an estimated percent wear, and the app projects a changeout date for each blade position. On the FM8 Tensioning System, remote monitoring of blade health and remaining blade life is an available option.
Product Performance & Technical
-
In head-to-head field trials against premium tungsten carbide tips, FM8 Knife Tips consistently deliver 3-4x longer wear life in high-abrasion applications like iron ore and copper mining. The patented geometry maintains consistent cleaning pressure throughout the wear cycle, unlike traditional tips that degrade rapidly once the edge rounds. Actual life depends on material abrasiveness, belt speed, and loading conditions, but our customers typically report 6-12 months between tip replacements compared to 2-3 months for conventional carbide tips.
-
No. Unlike early carbide tip designs that could catch and damage mechanical fasteners, FM8 Knife Tips feature a patented retention and geometry system that is safe for all belt splice types – including vulcanised, mechanical (clipper, alligator, rivet), and staple-style fasteners. This was a key design criterion from the outset, ensuring you get premium cleaning performance without risking expensive belt damage or splice failure.
-
FM8 primary cleaners and Knife Tips are designed for standard belt widths from 450mm to 2400mm (18" to 96"), with custom solutions available for specialised applications. Our systems accommodate belt speeds up to 5 m/s (1,000 fpm) in standard configuration, with high-speed variants available for faster operations. Contact our engineering team for specifications outside these ranges.
-
In many cases, yes. FM8 offers adapter systems that allow our Knife Tips to be installed on most major primary cleaner brands. However, for optimal performance, we recommend our complete FM8 primary cleaner system with integrated tensioner technology. The combination of patented Knife Tips and our adaptive tensioner delivers performance that retrofits alone cannot match. Our site assessment team can evaluate your existing equipment and recommend the best approach.
INDUSTRY & APPLICATIONS
-
Carryback is an environmental and safety hazard – spillage creates housekeeping hazards, dust emissions affect air quality, and material loss represents wasted resources. FM8's superior cleaning efficiency eliminates up to 99% of carryback, dramatically reducing these risks. Our customers report improved workplace safety scores, reduced cleanup labor, and better environmental compliance. Additionally, our longer-lasting Knife Tips reduce waste from frequent blade replacements.
-
While specific ROI depends on your operation, FM8 customers typically see payback within 3-6 months through reduced carryback cleanup labor, extended blade life (3-4x longer), reduced belt wear from over-tensioning, and eliminated unplanned shutdowns for cleaner maintenance. One Pilbara iron ore operation reported annual savings of 180,000 after switching to FM8 systems – calculated from labor reduction alone, not including improved production uptime. We provide ROI calculators and can project savings specific to your operation during our site assessment.
-
Absolutely. FM8 technology excels in challenging applications where traditional cleaners fail. Our Knife Tips maintain cleaning performance in wet coal, sticky bauxite, or clay-rich iron ore that would clog or glaze conventional blades. The constant pressure from our tensioner system ensures the blade maintains contact even when material adheres to the belt surface. We have specific formulations and configurations for high-moisture or cohesive materials – ask about our specialty applications.
