Spiral Idlers Key Specifications

Spiral Design

Helical rubber or steel strips wound around a central tube create gaps that prevent cement dust and fine powder from accumulating on the roller surface.

Anti-Buildup Function

Spiral gaps allow cement dust carryback to fall through rather than compacting on the roller, eliminating the material buildup common with smooth return rollers.

Roller Diameter

108 mm to 139.7 mm overall diameter with 63.5-76.1 mm core tube, sized for cement plant return strand belt widths up to 1600 mm.

Spiral Material

Rubber strip (60 Shore A) or mild steel flat bar helically wound and welded to the core tube for different cement dust adhesion levels.

Rotation Direction

Left-hand and right-hand spiral wound rollers paired to push carryback material outward from belt center in opposite directions.

Bearing & Seal

Sealed deep groove ball bearings with multi-stage labyrinth seals rated for continuous cement dust exposure on return conveyor runs.

Industrial Applications

Clinker Conveyor Return Anti-Buildup
Spiral idlers on clinker conveyor return strands prevent clinker dust compaction on rollers that causes belt tracking issues and premature bearing failure.
Cement Mill Product Conveyor Return
Finished cement carryback on return belts is actively shed by spiral idlers, preventing the hard cement crust formation that damages standard return rollers.
Raw Meal Conveyor Return Strand
Spiral idlers on raw meal conveyor returns handle the fine limestone-clay mixture carryback that adheres to smooth rollers in humid conditions.
