Conveyor Return & Cleaning Solutions

Rubber Disc Return Cleaning Conveyor Idler Roller

Engineered for belt conveyor return sections handling sticky, wet, or abrasive bulk materials. Rubber rings flex under rotation to break loose carryback and protect conveyor belts from abrasive wear.

Self-Cleaning Action on the Return Belt

Installed on the lower return run of bulk belt conveyors, the rubber disc roller breaks up fugitive material adhering to the belt surface. Spaced rubber rings reduce surface contact, allowing dislodged material to drop freely without caking or causing belt mistracking.

Carryback Prevention

Grooved rubber disc profile prevents sticky buildup on steel shells, eliminating localized shell wear.

Belt Life Protection

Elastic natural/synthetic rubber rings absorb residual vibration and reduce cover rubber abrasion.

Corrosion & Slurry Resistance

Multi-labyrinth sealed bearings protect internal assemblies in wet, dusty, and corrosive washdown areas.

Typical Working Applications

Sticky Ore & Coal Conveying: Prevents sticky fines and coal dust accumulation on return belts.

Quarry, Aggregate & Sand Plants: Dislodges wet sand and slurry to avoid uneven roller wear.

Fertilizer & Chemical Bulk Handling: Resists chemical salt caking and corrosive material deposits.

Cement, Ash & Clinker Lines: Protects conveyor belts against abrasive particulate carryback.

Frequently Asked Questions

Q1: Where should rubber disc return rollers be positioned?
They are installed on the return belt strand near discharge points and along dirty-side sections where carryback tends to stick.

Q2: How are the rubber rings fastened to the steel core?
Rings are heavy-interference press-fitted onto the carbon steel pipe and secured with heavy-duty end retaining rings to prevent axial shifting.

Q3: Can shaft ends be customized to fit existing conveyor brackets?
Yes. Standard flat-milled slots, round shafts with keyways, or threaded ends can be machined according to your conveyor frame drawing.
