Product Description

Key Features The spiral roller is made of high-frequency welded pipe, high-density nylon sealing ring, spiral spring, bearing, round steel, etc.

Spiral rollers, also called rubber spiral rollers or steel spiral rollers, are a special type of roller used in conveyor belt systems. Unlike standard smooth rollers, spiral rollers have a continuous helical (screw-like) pattern on their surface. This unique design is primarily used to clean the return side of the conveyor belt and assist with belt tracking.

Spiral/Screw Pattern: The most notable feature is the continuous helical pattern (similar to threads) molded into the surface of the roller. This pattern can be made of rubber (for general cleaning and conveyor belt protection) or steel (for more aggressive cleaning in heavy-duty applications). Rotational Cleaning Action: As the conveyor belt moves over the spiral roller, the spiral pattern causes the roller to rotate. This rotation, combined with the angled nature of the "threads", helps to clean and remove sticky or abrasive material that may adhere to the underside of the belt (called "back-stripping"). Belt Tracking Aid: The spiral structure also allows the belt to self-center. If the belt begins to stray, the angled design of the spiral cleverly guides it back to center, aiding in overall belt tracking. Rugged Construction: Similar to other idlers, they feature a rugged shaft, durable frame, and sealed bearings to withstand tough material handling conditions, including abrasive materials and environmental contaminants.

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.
