Spiral Idlers Key Specifications

UGES spiral idlers for power plants feature helical SBR rubber strips on 89-127 mm corrosion-resistant rollers. Left/right-hand spiral pairs actively shed wet coal fines and ash carryback on CHP return strands, preventing the buildup that causes roller seizure.
icon
Spiral Design
Helical rubber strips wound on steel core tube create self-cleaning gaps that prevent wet coal fines from building up on return rollers in CHP conveyors.
icon
Anti-Buildup Performance
Spiral openings shed wet coal dust and sticky fly ash carryback that would compact on smooth return rollers in humid power plant environments.
icon
Roller Diameter
89 mm to 127 mm overall diameter with corrosion-resistant core tube for outdoor CHP return strand applications.
icon
Spiral Material
SBR rubber strips (55-65 Shore A) with wear-resistant compound, helically wound for optimal coal fines shedding performance.
icon
Spiral Pairing
Left-hand and right-hand spiral pairs installed alternately to push coal carryback outward from both belt edges on CHP return strands.
icon
Corrosion Resistance
Galvanized or epoxy-coated core tubes and end caps to resist corrosion from wet coal dust and acidic ash residue in power plants.

Industrial Applications

Power plant spiral idlers are essential on CHP main conveyor returns, ash handling system returns, and outdoor coal yard conveyor return strands. Their self-cleaning design prevents wet coal and ash buildup in humid operating conditions.
Application 1

CHP Return Strand Coal Fines Shedding

Spiral idlers on main CHP conveyor return strands actively remove wet coal fines that would otherwise compact into hard deposits on standard rollers.
Application 2

Ash Handling Conveyor Returns

On fly ash and bottom ash conveyor return strands, spiral idlers shed sticky alkaline ash residue that corrodes and jams smooth return rollers.
Application 3

Outdoor Coal Yard Conveyor Returns

In rain-exposed coal yard conveyors, spiral idlers prevent the wet coal paste buildup that causes return roller seizure and belt tracking problems.
