The Spiral Return Roller is designed for the return side of belt conveyor systems, providing stable belt support while helping remove sticky materials and carryback from the conveyor belt surface.
Featuring a steel spiral structure, the roller creates a self-cleaning effect during rotation, helping reduce material buildup and maintain cleaner belt operation. The wear-resistant spiral design is suitable for conveying applications where sticky materials, dust, and abrasive materials may affect conventional return rollers.
Manufactured with a thick-wall roller tube, flexible rotation performance, and low running resistance, the Spiral Return Roller provides reliable operation for continuous bulk material conveying applications.
Key Features
Self-Cleaning Spiral Structure
The spiral roller surface continuously contacts the return belt during operation, helping remove adhering materials and reduce material accumulation around the roller.
Wear-Resistant Steel Construction
The steel spiral structure provides excellent wear resistance and mechanical durability, making the roller suitable for demanding conveyor environments with abrasive or sticky materials.
Efficient Return Belt Support
Designed for the return side of belt conveyors, the roller provides stable belt support while helping maintain cleaner belt operation and reduce carryback problems.
Reliable Sealing Protection
The roller uses a labyrinth sealing structure combined with double-sealed bearings to create effective protection against dust and moisture, helping improve bearing reliability.
Smooth and Low-Resistance Operation
The thick-wall roller tube and precision manufacturing provide flexible rotation, low running resistance, and stable performance during continuous operation.
Product Advantages
Self-cleaning performance: Spiral structure helps remove sticky materials and carryback from the return belt.
Reduced material buildup: Helps prevent material accumulation that may affect roller rotation and conveyor performance.
High wear resistance: Durable steel spiral construction supports long-term operation in abrasive environments.
Reliable bearing protection: Labyrinth sealing and double-sealed bearings help protect internal components from dust and moisture.
Stable conveyor operation: Smooth rotation and low resistance improve overall conveying reliability.
Applications
The Spiral Return Roller is installed on the return side of belt conveyor systems where material carryback, sticky materials, or belt contamination may affect conveyor performance. Its self-cleaning spiral structure helps maintain cleaner belt operation and reliable roller performance in continuous conveying applications.
Typical applications include:
Mining and Quarrying: Used on conveyor return sections handling ores, aggregates, and other bulk materials where material carryback may accumulate.
Sand and Gravel Processing: Suitable for conveying systems where wet or sticky materials can adhere to the return belt.
Iron and Steel Metallurgy: Used in material handling systems requiring wear-resistant conveyor components.
Cement and Building Materials: Suitable for conveying abrasive or powdery materials where buildup control is important.
Ports and Bulk Material Terminals: Used in continuous conveying systems where material accumulation may affect belt operation.
Hydropower and Infrastructure Projects: Suitable for bulk material conveying systems requiring reliable return belt support.
General Bulk Material Handling: Suitable for conveyor applications involving sticky, dusty, or abrasive materials.
Ordering & Quotation Information
