Product Description

Key Features V-Shaped Roller Configuration: Unlike a flat or single cylindrical return idler, this type consists of two rollers angled upwards from the center, forming a "V" shape. This V-shape inherently helps to center the belt. Comb-like Discs/Rings: Along the surface of these V-shaped rollers, there are a series of closely spaced, independent discs or rings, resembling the teeth of a comb. These discs are typically made from durable, wear-resistant materials like rubber or steel. Cleaning Action: As the conveyor belt passes over the V-shaped comb idler, the individual discs rotate. The gaps between the discs, combined with the rotation and the pressure from the belt, effectively dislodge and shed sticky, wet, or abrasive material that has adhered to the underside of the belt after the discharge point. Tracking Assistance: The V-shape itself provides a natural self-centering action.
When the belt starts to drift off-center, the angled rollers generate a force that guides the belt back towards the middle,
contributing to better overall belt tracking. Robust Construction: Like other conveyor idlers, they are built with strong frames,shafts, and sealed bearings to withstand harsh operating conditions and abrasive materials.

Performance Benefits

Effective belt cleaning: The primary benefit is the ability to effectively remove sticky, wet, or fine material that adheres to the return side of the belt after it has been unloaded. This is a continuous, passive cleaning operation.

Prevents material buildup: Spiral idlers prevent material buildup on return idlers, pulleys, and conveyor structure by continuously cleaning the belt. Material buildup can lead to premature component wear, belt mistracking, and increased power consumption.

Assists belt mistracking: The spiral structure provides a gentle, yet effective, self-centering action for the belt. This helps keep the belt properly tracked, which reduces edge wear and extends belt life.

Reduced Maintenance and Downtime: Less material buildup means less frequent manual cleaning of rollers and pulleys, resulting in lower maintenance labor costs and increased uptime.

Extended Component Life: By keeping belts and rollers clean, spiral idlers help reduce wear on rollers, pulleys, and the belt itself, extending the life of these expensive components.

Scraper Replacement: In certain applications, especially on mobile conveyors, or where traditional belt scrapers are impractical or difficult to maintain, spiral idlers can be an effective replacement or supplement for belt cleaning.

Passive Operation: They operate passively, with the cleaning and tracking action derived from the motion of the belt itself, requiring no external power source.

Applications Mining and quarrying: Widely used for conveying wet and sticky materials such as wet coal, fine ore, clay or wet aggregates, which often adhere to the belt surface.

Aggregate and cement plants: Wet sand, crushed stone or fine cement clinker can cause serious carryback and accumulation problems.

Power plants: Especially suitable for coal conveying systems that handle wet or fine coal.

Waste management and recycling centers: For conveying various wet or sticky municipal solid waste, organic waste or recycled materials that tend to adhere to the belt.

Fertilizer and chemical plants: For conveying hygroscopic or sticky chemical compounds that may produce residues.

Any conveying system with carryback problems: When conveying sticky, wet or fine materials, keeping the return belt clean is essential to prevent accumulation, deviation and damage.
