Conveyor Belt Cleaners Engineered to Exceed in Demanding Mining Environments
International Patents Pending Knife Tips and the FM8 Tensioning System, engineered for constant blade-to-belt pressure in iron ore, coal and bulk materials handling. Prove blade life on your own conveyor first.
Innovation Focus
FM8 designs for the pressure at the belt, not just the force at the tensioner. The FM8 Tensioning System pairs a constant pressure tensioner with constant pressure primary blades, engineered to hold blade-to-belt pressure from new to worn. International Patents Pending.
Engineered for Performance
Engineered for Australian mining conditions, FM8 blades and the FM8 Tensioning System are designed to keep cleaning performance steady from installation to changeout, with fewer mainframe resets and planned isolations.
Australian Engineering. Global Reach.
Designed and field-tested in Australian mining and bulk materials handling operations, including iron ore, coal and mineral processing. FRAS-rated blades are available for underground coal.
FM8- Engineered to Exceed.
FM8's Knife Tip scraper blades and the FM8 Tensioning System are the subject of international patent applications (International Patents Pending). Prove the difference on your own conveyor with a Verified Validation Trial.

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
-
Blade life depends on belt speed, tonnage, product abrasiveness, splice frequency and tensioner condition, so FM8 does not quote a single figure. In an FM8 Verified Validation trial at a Bowen Basin underground coal operation in July 2026, the FM8 Super XHD FRAS primary blade ran over five and a half weeks, against about two weeks for competitor FRAS blades under the same conditions. Results are site-specific. A Verified Validation Trial lets you measure blade life on your own conveyor.
-
Not with a metal edge. A rigid knife-tip edge meets a row of fasteners on every pass, so FM8 does not offer metal-edged Knife Tips for mechanically spliced belts, including underground coal trunk belts. Knife Tips suit vulcanised belts. For mechanically spliced belts, tell us your splice type and FM8 Engineering will recommend the right blade. The FM8 Tensioning System also retracts the blade to ride over a mechanical splice and returns it to its setting behind the splice.
-
Your belt width, belt speed, product (and whether it is wet, dry or sticky), splice type, current blade and mainframe, tensioner type, and whether FRAS certification is required. Australian operations are supported through your FM8 Distributor, and international enquiries are handled by FM8 Engineering directly. Phone 1800 581 501 or email info@fm8.global.
-
Yes. The FM8 Tensioning System picks up your existing tensioner mounting holes and accepts standard industry XHD blades, so you can fit the tensioner first, run down your existing blade stock, and move to FM8 constant pressure blades at a changeout of your choosing. Retrofit compatibility depends on the mainframe and mounting arrangement in service and is confirmed for each installation. The system is specified for surface conveyor installations.
INDUSTRY & APPLICATIONS
-
Carryback creates spillage, dust and housekeeping work under the conveyor, and each blade or tensioner adjustment means access to the head pulley zone. Cleaner contact that holds up through the blade's life reduces carryback, and the FM8 Tensioning System removes recurring mainframe resets and their isolations. The Super XHD blade also cuts polyurethane wastage by 25%. FM8's FRAS-rated range is certified for underground coal.
-
FM8 does not publish a standard payback figure because it depends on your site. The main cost drivers are blade consumption, planned isolations for changeouts and resets, clean-up labour, and idler and belt cover damage. FM8 runs the comparison as a lifecycle cost on your own site data, and a Verified Validation Trial gives you measured blade life to put into it. Contact FM8 for a site-specific comparison.
-
Wet and sticky product changes the duty, so FM8 selects the blade from your product, belt speed and conveyor rather than from a single rule. Constant blade-to-belt pressure helps the blade hold contact as it wears, and for coal and slurry duty FM8 offers Super XHD Orange, a PTMEG polyether polyurethane. Send FM8 Engineering your product and belt details and we will recommend a configuration.
