Return Idlers Key Specifications

Configuration

Flat return and V-return (10° tilt) options for coal handling plant conveyors, with V-return preferred for wet coal carryback management.

Roller Diameter

76.1 mm to 114.3 mm ERW steel tube rollers with anti-corrosion coating for outdoor CHP conveyor return strands.

Surface Treatment

Epoxy-coated or rubber-lagged return rollers to prevent wet coal fines adhesion and reduce carryback buildup in humid conditions.

Bearing Protection

Sealed deep groove ball bearings with nylon cage and grease-filled labyrinth seals rated for outdoor operation in coal dust environments.

Frame Material

Hot-dip galvanized steel brackets resistant to coal dust corrosion and acid condensation in power plant conveyor galleries.

CEMA Rating

CEMA Class II-III with design life of 25,000+ hours for continuous return strand support on CHP trunk and feeder conveyors.

Industrial Applications

CHP Trunk Conveyor Return Strand
Return idlers on main coal handling plant conveyors manage coal fines carryback from the belt surface across long conveyor gallery runs.
Ash Conveyor Return Belt Support
Corrosion-resistant return idlers for bottom ash and fly ash conveyor return strands where alkaline ash residue accelerates roller degradation.
Coal Yard Stacker Conveyor Return
Outdoor return idlers on stacker-reclaimer conveyors exposed to rain, coal dust, and temperature variations require weatherproof sealed bearings.
