A Field Guide to Types of Belt Cleaners: Trends, Specs, and Real-World Picks
If you handle bulk material, you eventually become obsessed with carryback. It’s messy, it’s costly, and—if we’re honest—it’s totally preventable with the right types of belt cleaners. I’ve toured enough quarries, cement plants, and ports to see what works, what clogs, and what quietly saves maintenance crews every weekend.
Industry snapshot: where cleaners are headed
Two big shifts stand out: self-adjusting tension systems (less fiddling, more uptime) and smarter blade materials. Polyurethane and ceramic-tipped primary blades dominate head pulleys; rubber-based secondary and “return” cleaners (like the non-working side units) are rising fast in wet, sticky duties. ESG and safety rules push dust control—OSHA and EU directives aren’t going away—so reliable cleaning is not “nice to have” anymore.
Meet the product: Nonloaded Cleanser for Belt Conveyor
This empty-section cleaner targets the non-working (return) side. The scraper uses wear-resistant rubber plates; the blade head is designed to resist wear, corrosion, and breakage without scarring the belt. A parallel mechanism keeps even pressure and auto-adjusts as the blade wears—surprisingly simple, actually.
Typical specifications (real-world use may vary)
| Blade material | Wear-resistant rubber (Shore A ≈ 85±5); optional PU |
| Frame | Carbon steel with epoxy; SS304 optional |
| Belt width compatibility | ≈ 500–2000 mm |
| Belt speed | Up to ≈ 3.5 m/s |
| Operating temp | −20 to +80 °C (high-temp options on request) |
| Tensioning | Parallel mechanism, auto-compensating |
| Service life | ≈ 12–24 months depending on load, fines, and moisture |
| Testing | ASTM G65 abrasion; ASTM B117 salt spray (frame coating) |
| Standards | CEMA 576 for application class; ISO 9001 factory QA; CE; optional ATEX |
Where each cleaner fits (quick tour)
- Primary cleaners (tungsten-carbide/PU) at head pulley: high-speed belts, dry to slightly wet material.
- Secondary cleaners (segmented, spring/air tension): sticky ores, cement clinker carryback.
- Return/empty-section cleaners: mud-heavy aggregates, coal fines, recycling—less belt wear risk.
In many audits, a combo of primary + secondary + return delivers the holy grail: types of belt cleaners working together so carryback is barely a rumor.
Process, materials, and QA (how it’s built)
Materials: wear-resistant rubber compounds (ASTM D2000 classification), epoxy-coated steel frames. Methods: precision vulcanization of blades, jig-welded frames, and pre-tension checks. Testing: abrasion per ASTM G65; coating per ASTM B117 (≥240 h); application selection per CEMA 576. Plants usually log service life in PM systems—many customers say return cleaners stretch beyond a year in limestone.
Vendor comparison (indicative)
| Vendor | Cleaner Focus | Tensioning | Lead Time | Certs |
|---|---|---|---|---|
| HG Conveyor (Nonloaded Cleanser) | Return/empty-section | Auto parallel | ≈ 2–4 weeks | ISO 9001, CE, optional ATEX |
| Global Brand A | Primary + secondary | Spring/air | ≈ 3–6 weeks | CE, UL (select), ATEX |
| Regional OEM B | Secondary | Manual | ≈ 1–3 weeks | Varies |
Customization and use cases
Options include custom belt-width brackets, stainless frames for corrosive plants, higher-durometer blades for hot clinker, and ATEX labeling. In ports and aggregates (Hebei to, say, Queensland), the non-working side cleaner quietly reduces washdown. One cement line I visited cut cleanup hours by ≈40% and measured carryback reduction of 60–80% after pairing a return cleaner with a segmented secondary—your mileage may vary, but crews noticed.
What users report
“Less belt damage risk,” a maintenance lead told me, “and we don’t have to babysit the tension.” Another noted smoother idlers on the return run—fewer fines riding back is the whole point of deploying multiple types of belt cleaners.

Selection tips
- Classify your duty per CEMA 576 (light to very heavy).
- Match blade to material: rubber for damp fines, PU/ceramic for abrasion.
- Prefer auto-tension to avoid drop-off in performance over time.
- Check certifications (CE, ISO 9001) and, if needed, ATEX for dust zones.
