Fluent supplies secondary belt scrapers that remove residual carryback after the head pulley. Belt widths 12"–96", speeds up to 1500 fpm. Polyurethane and tungsten carbide blades available.
High-performance secondary belt cleaners for efficient material removal.
Match belt width, speed, and mounting clearance to available models. All secondary cleaners accommodate mechanical and vulcanized splices, though blade material selection affects compatibility. Consider the operating environment and material characteristics when selecting a cleaner type.
We support all belt scrapers with a full line of accessories and replacement cleaner blades.
Segmented urethane or carbide-tipped blades with manual or spring tensioning. General-purpose design handles most dry materials at moderate speeds. Cartridge or pin-based blade replacement for routine maintenance.
Add a secondary scraper when primary cleaning cannot remove enough carryback. Most conveyors benefit from pairing primary and secondary cleaners to achieve 90–95% total carryback removal compared to 60–70% from primary scrapers alone.
Add a secondary cleaner if:
Carryback removal must exceed 90%
Material is sticky, wet, or creates dust problems
Cleanup labor costs justify additional equipment investment
Return idler or belt damage occurs from material accumulation
Product contamination from carryback creates quality issues
Multiple secondary cleaners can be staged along the return path for maximum removal in extreme applications. Some limited-duty installations use secondary cleaners as standalone solutions on portable conveyors, stackers, and chute-fed systems where full primary + secondary systems prove uneconomical.
Secondary cleaners mount just after the head pulley where the belt is flattest, positioned close enough to return removed material to the main material stream rather than creating spillage beneath the conveyor.
Start with application material characteristics, belt speed, and available clearance.

Match the cleaner duty class to operating conditions and tonnage. Choose blade material based on abrasiveness and splice type. Budget maintenance access and blade replacement frequency into the selection.
Premium blade materials built for durability and long-lasting performance.
Polyurethane blades suit most applications and accommodate mechanical splices. Tungsten carbide extends life 2–3x in abrasive materials but costs 40–60% more. Segmented designs conform to worn belts and pass over mechanical fasteners without damage. Durometer selection (60–90 range) balances cleaning efficiency with belt protection.
Secondary scrapers use higher blade pressure than primary systems to remove embedded fines. Proper tensioning maintains consistent contact across the full belt width while allowing deflection for mechanical splice fasteners.
Ratchet or twist tensioners with visual indicators. Operators adjust during routine inspections based on blade wear. Suit applications with regular maintenance schedules.
Spring or pneumatic mechanisms maintain constant blade pressure as wear occurs. Initial cost is 30–50% higher but reduces maintenance labor. Recommended for continuous operations, high blade wear applications, or limited-access installations.
Position the secondary cleaner as close to the head pulley as practical to return material to the main stream. Mount a support roller for stability and consistent blade pressure. Provide clearance for blade replacement without removing large guarding sections. Verify that removed material returns to the material flow rather than creating spillage beneath the conveyor.
Push-up: blade assembly pushes upward against the belt from below.
Pull-up: tensioner pulls the blade assembly upward from above.
Selection depends on chute configuration and access requirements
Mounting brackets attach to the conveyor structure or roller supports. Adjustable brackets accommodate variations in belt tracking and pulley alignment. Multiple secondary cleaners can be staged along the return path for maximum removal. Some installations use pressure rollers to stabilize the belt where clearance prevents a pulley-mounted installation.
Inspect secondary scrapers every 30–90 days, depending on material abrasiveness and operating hours.
Reduced blade height (replace at approximately 50% of original thickness)
Torn edges or separated segments
Hardening or cracking in urethane
Dulled or missing carbide tips
Replace blades before complete wear allows backing plates to contact the belt surface. Waiting until complete wear causes belt damage far exceeding blade replacement cost.
Cartridge systems: Release tension, remove retaining pins or fasteners, slide the worn cartridge out, insert a new cartridge, and restore tension. Learn how to replace a primary belt scraper blade for similar procedures.
Tensioner maintenance: Verify smooth adjustment operation, check spring tension or pneumatic pressure, and inspect mounting hardware torque.
Common issues and corrections:
Excessive carryback with good blades: Check tension adjustment first
Noise or vibration: Inspect mounting hardware, torque, and blade segment integrity
Uneven blade wear: Address belt tracking problems before installing new blades
