Heavy-Duty DIN 22255 Mining Compact Chains for Low-Profile Conveyors

Heavy-Duty DIN 22255 Mining Compact Chains for Low-Profile Conveyors

The mining compact chain can replace the currently commonly used round link chains with the same nominal diameter, and there is no need to modify the existing scraper conveyors. When using the mining compact chain, it also allows the use of lower side coal retainers for the scraper conveyors.

High-Strength DIN 22255 Compact Mining Chains for High-Performance Conveyors | YD

As an industry-leading manufacturer with 20 years of specialized experience, YD provides premium Mining Compact Chains designed for high-capacity Armored Face Conveyors (AFC). Our low-profile compact chains are the ideal solution for mines requiring maximum power transmission within restricted spatial envelopes, offering a superior alternative to standard round link chains.

Key Technical Specifications:

  • Standard:Engineered in strict accordance with DIN 22255 and high-grade industry specifications.
  • Design:Low-profile geometry allows for larger chain diameters in existing conveyor troughs, significantly increasing breaking load capacity.
  • Material:Forged from specialized premium alloy steel (CrNiMo) to withstand extreme dynamic loads.
  • Automated Production:Manufactured using high-precision automated welding lines, ensuring uniform link geometry and perfect pitch consistency.
  • Heat Treatment:State-of-the-art continuous hardening and tempering process results in an optimized microstructure for superior fatigue resistance.

Why Choose YD Compact Mining Chains?

  • Increased Power Density:Our compact design allows you to upgrade your conveyor’s breaking force without needing to replace the entire trough system.
  • Superior Wear Resistance:The flattened outer profile increases the contact area with the sprocket and flight bars, drastically reducing inter-link wear and extending service life.
  • Exceptional Fatigue Strength:Designed to endure the constant cyclic loading of high-output longwall mining operations.
  • Strict Quality Assurance:Every meter of chain undergoes 100% proof load testing and non-destructive testing (NDT) to guarantee zero-defect delivery.

Applications:

Our mining compact links are specifically engineered for:

  • Ultra-Heavy-Duty Armored Face Conveyors (AFC).
  • Beam Stage Loaders (BSL)in restricted underground seams.
  • High-Capacity Scraper Conveyorsin coal and potash mining.
  • Extremely Abrasive Material Handlingwhere standard chains fail prematurely.

Direct Factory OEM Services:

YD is a trusted Chinese manufacturer offering tailored solutions for global mining groups. We provide Custom OEM Services, including specific surface coatings and customized dimensions, to ensure our compact chains integrate seamlessly with your existing mining machinery.
