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.
