Steel Cord Conveyor Belt for coalmine
1. Core Safety & Compliance Standards
Flame Resistance:
Alcohol Burn Test: ≤3s average flame time; ≤10s single value.
Propane Burn Test: Minimum undamaged length ≥600mm after exposure.
Anti-static Property: Surface resistance ≤3×10⁸ Ω .
Certifications: Mandatory (coal safety certification, quality reports, product certificates) for Chinese mines.
2. Technical Specifications
Structural Design
Steel Cords: High-strength galvanized open-strand steel cords for low elongation (≤0.25%) and high adhesion to rubber.
Cover Compounds: Flame-retardant rubber covers (top/bottom) with:
Tensile strength ≥15–25 MPa
Elongation at break: 350%–450%
Abrasion resistance: 60–200 mm³.
Reinforcement: Anti-tear layers (e.g., transverse fabric or buffer sheets) to resist impact.
3. Application-Specific Features
Underground Coal Mines: Optimized for high-speed (≥6.7 m/s), high-capacity (up to 11,000 t/h) transport in explosive environments.
Long-Distance Haulage: Low elongation (0.25%) reduces tensioning needs, cutting infrastructure costs.
Incline Capability: Suitable for steep inclines (≤20°) with diamond-pattern surfaces for enhanced grip.
