Spiral Idler

Spiral Idler is a special conveyor idler with a helical/spiral surface structure,mainly used for belt centering,self-cleaning,anti-deviation and material scattering prevention in belt conveyor systems.

Key Features

Automatic Belt Centering&Anti‑deviation

The spiral design produces a centering force during rotation,effectively correcting belt running and reducing side wear.

Self‑cleaning Function

The spiral surface continuously scrapes sticky materials,powder and debris from the belt,avoiding buildup and jamming.

Stable Running&Low Vibration

Smooth spiral profile ensures stable belt operation,reduces vibration,noise and impact on the conveyor structure.

High Wear&Corrosion Resistance

Available in steel,rubber-coated or polyurethane materials for long service life in mining,cement,coal and other harsh conditions.

Easy Installation&Maintenance

Standard size and structure,compatible with most conveyor frames,simple to replace and maintain.

Applications

Mining,quarry,coal and ore conveying

Cement,power plant,steel and building material lines

Conveyors handling sticky,wet or powdery materials

Belt conveyors needing anti-deviation and self-cleaning

Port,dock and bulk material handling systems
