Self-Cleaning Idlers Key Specifications

Shedding Mechanism

Individual rubber discs flex and shed wet coal paste and sticky ash during rotation, preventing the continuous material film that traps moisture on smooth rollers.

Disc Configuration

15-35 rubber discs per roller at 30-50 mm spacing optimized for wet coal fines and fly ash adhesion characteristics in CHP environments.

Roller Diameter

89 mm to 133 mm overall diameter self-cleaning assemblies for CHP return strand applications on 800-1800 mm wide belts.

Disc Material

SBR rubber discs (50-60 Shore A) with low-adhesion surface compound specifically formulated for wet coal and ash carryback resistance.

Weather Resistance

UV-resistant disc compound and galvanized shaft/end caps for outdoor CHP conveyor return installations exposed to rain and sunlight.

Bearing & Seal

Sealed bearings with grease-purge fitting for periodic relubrication, rated for wet coal dust and outdoor CHP operating conditions.

Industrial Applications

Wet Coal Return Belt Cleaning
Self-cleaning idlers on CHP trunk conveyor returns shed wet coal paste that forms during rain and high-humidity conditions in coal handling areas.
Fly Ash Conveyor Return Cleaning
On ESP and bag filter fly ash conveyor returns, self-cleaning discs prevent sticky alkaline ash carryback from compacting on return rollers.
Coal Yard Reclaim Conveyor Returns
Outdoor coal yard reclaim conveyor returns require self-cleaning idlers to handle rain-soaked coal fines that adhere aggressively to standard rollers.
