Overview
The Double Ring Chain Scraper Conveyor is a heavy-duty conveying system designed for harsh industrial environments, particularly in mining and bulk material handling. Its distinguishing feature is the double ring chain mechanism, which significantly improves durability compared to single-chain designs. This equipment is engineered to transport loose materials like coal, ore, and aggregates horizontally or at inclinations up to 30°. The robust construction allows it to operate continuously under high-load conditions, making it a preferred choice for large-scale material handling operations.
Structure and Working Principle
The conveyor consists of a trough, scraper flights attached to the double ring chains, drive unit, and tensioning device. The chains operate in parallel, connected by crossbars that hold the scrapers, forming a continuous loop within the trough. Material is dragged along the trough by the moving scrapers. The dual-chain design distributes load more evenly, reducing stress concentrations that cause wear in single-chain systems. Drive sprockets engage with the chain rings to propel the system, while adjustable tensioners maintain optimal chain tautness.
Key Features
1) Enhanced durability: The interlocking double ring chains are typically made from alloy steel with hardness ratings of 40-50 HRC, providing 2-3 times longer service life than standard chains. 2) High capacity: Capable of handling 100-1,500 tons/hour depending on model, with trough widths ranging from 400mm to 1,200mm. The dual-chain system allows for higher pulling forces without chain elongation issues common in single-chain designs.
Application Areas
Primarily used in underground coal mines for longwall face haulage and gate road applications. Also widely deployed in: - Cement plants for raw meal and clinker transport - Power stations for ash handling - Metallurgical operations for ore and slag conveyance - Tunnel construction for muck removal The sealed trough design makes it suitable for dusty environments, while the robust construction withstands impact from large lump materials.
Maintenance and Precautions
Regular maintenance is critical for optimal performance. Key practices include: 1) Chain lubrication: Apply specialized chain lubricant every 50-100 operating hours. Automatic lubrication systems are recommended for continuous operations. 2) Tension monitoring: Check chain tension weekly; proper tension should allow 2-3cm of vertical movement at mid-span. Over-tensioning accelerates wear, while under-tensioning causes slippage.
B2B Procurement Guide
When sourcing double ring chain conveyors, consider: 1) Material specifications: For abrasive materials like iron ore, specify chains with tungsten carbide overlays. Coal applications may use standard alloy chains to reduce costs. 2) Customization options: Many manufacturers offer modular designs allowing length adjustments, variable trough angles (0°-30°), and explosion-proof configurations for hazardous areas. Lead times typically range 8-12 weeks for standard models, with premium suppliers offering 24/7 technical support and spare parts availability guarantees.
