Why is a belt cleaner important?
Without cleaning, carryback wears pulleys and idlers, causes mistracking and creates housekeeping and safety hazards under the conveyor.

Alloy Cleaner
橡胶合金清扫器(YH-P)
Primary conveyor belt cleaners with alloy or tungsten-carbide blades that strip carry-back straight after the head pulley, before it reaches the return idlers.

Usage
Usage
Rubber-Alloy Belt Cleaner (YH-P) — a secondary (2nd-stage) scraper with a tungsten-alloy blade in a rubber mount, fitted just behind the primary cleaner on the return run. It shaves off the hard, sticky or abrasive carryback the first stage leaves, so the belt reaches near-clean; the alloy edge outlasts polyurethane on wet, clayey or high-wear ores.
Operating conditions
Operating conditions
| Working temperature | PU blades -40 °C to +80 °C; ceramic-tipped blades up to +500 °C — confirm per model. |
|---|---|
| Dusty environment | Suitable — PU or ceramic blades are unaffected by dust; no bearings to contaminate |
| Moisture & water | Suitable — PU blades and coated steel bodies take washdown; stainless for continuous wet duty |
| Corrosive environment | Stainless blade holders available — powder-coated steel for ordinary acid or alkali, stainless for high-salinity sites |
| Certification | MA coal-mine safety certified versions available — confirm the certified SKUs for your project |
| Outdoor use | Suitable — coated and stainless options for coastal and weathering service |
Technical overview
Belt cleaners scrape carryback off the return strand so material does not build up on pulleys, idlers and structure. HBXM offers primary and secondary cleaners with polyurethane or tungsten blades rated for wet, sticky and abrasive ores.
Primary vs secondary cleaner: which do I need?
Use a primary cleaner at the head pulley for bulk carryback, then a secondary cleaner downstream for the fine residual layer.
Which blade material lasts longest?
Polyurethane suits most dry and medium-abrasive ores; tungsten or ceramic-tipped blades are best for very hard, wet and sticky materials.
Can cleaners be retrofitted to an existing conveyor?
Yes. Our cleaners mount to standard stringer widths with adjustable tension and fit most head-pulley arrangements without conveyor modification.
Highlights
Features
Belt-width coverage
Covers belt widths 500–1800 mm across standard conveyor sections.
Self-adjusting tensioners
Spring / torque-arm tensioners keep blade contact uniform as the blade wears.
Polyurethane blade
PU compound Shore 85–95 A wipes carryback while staying gentle on the belt.
Modular mounting
Adjustable brackets fit B500–B2400 widths and head-pulley layouts.
Quick blade swap
Cartridges swap without removing the frame, cutting downtime.
Belt protection
Flexible wiping removes wet or dry carryback without damaging the carcass.

FAQ
Frequently asked questions
Where is a primary belt cleaner mounted?
On the head pulley, as close to the belt's tangent point as the chute allows — typically 15–30° past top dead centre, on the clean side.
How often do the blades need replacing?
In coal or aggregate duty, plan on a blade change every 3–12 months depending on abrasion; the segments are individually replaceable so you do not change the whole unit.
Will a scraper damage my belt?
A correctly tensioned cleaner with a suitable blade compound removes carry-back without nicking the cover. The common damage cause is over-tensioning or running a metal blade on a low-grade cover.
