High Tensile Strength DIN Standard Quality Black Steel Cord Elevator Belt Manufacturers

The steel cord rubber conveyor belt (also called wire rope core conveyor belt) is a heavy‑duty rubber reinforcement belt that uses high‑tensile galvanized steel cords as the load‑bearing skeleton, embedded in a rubber carcass. It is engineered for long‑distance, high load, high speed material transportation, widely applied in mining, coal, ports, metallurgy, power plants, and chemical industries.

It has a layered, integrated structure with four core parts:

• Steel Cord (Reinforcement Core)
  • Made of high‑carbon hot‑galvanized steel wires (7×7 or 7×19 stranding), arranged parallel longitudinally at equal spacing.
  • Tensile strength: 630–10,000 N/mm (ST630 to ST5000); elongation at full load: ≤0.25%.
  • Galvanized for anti‑corrosion; uniform tension ensures straight running and minimal drift.
• Core Rubber
  • Special adhesive rubber that fully penetrates gaps between steel cord strands.
  • Bonds tightly with steel cords, preventing rust, reducing shear/torsion between strands, and enhancing dynamic fatigue resistance.
• Top Cover Rubber
  • Thickness: 6–12 mm (heavy‑duty up to 15 mm); protects against abrasion, impact, cutting, and material wear.
  • Grades: wear‑resistant (X/Y/W), heat‑resistant, fire‑retardant, cold‑resistant, oil‑resistant, acid‑alkali resistant.
• Bottom Cover Rubber
  • Thickness: 3–6 mm; reduces friction with pulleys/idlers, absorbs vibration, and resists wear from the conveyor frame.
• Edge Rubber
  • Seals the belt sides, preventing cord exposure, water ingress, and edge cracking.

• Ultra‑High Tensile Strength
  Withstands heavy loads (up to 10,000 N/mm), ideal for long‑distance lines (5–20 km) and high‑capacity transport (thousands of tons per hour).
• Extremely Low Elongation
  Permanent elongation <0.25%; minimal tensioning required, reducing maintenance and enabling smaller‑diameter pulleys.
• Superior Impact & Tear Resistance
  Integrated steel‑rubber structure resists damage from sharp, heavy materials (e.g., rocks, coal); optional transverse steel/fiber reinforcement enhances tear resistance.
• Long Service Life
  Thick, high‑quality rubber covers resist aging, abrasion, and harsh environments; steel cords remain corrosion‑free, extending life to 5–15 years (2–3× longer than fabric belts).
• Good Troughability & Flexibility
  Flexible carcass adapts to trough idlers for stable material transport; excellent bending resistance for repeated pulley cycling.
• Reliable Splicing & Safety
  Vulcanized or mechanical splices maintain high strength; fire‑retardant/anti‑static grades meet underground coal mine safety standards.

This belt type is essential in industries requiring robust and reliable high-capacity transport:

• Mining: Main haulage lines in surface and underground mines for coal, metal ores, and overburden.
• Ports & Terminals: Ship loading and unloading of bulk materials like grains, coal, and minerals.
• Large-Scale Quarrying & Cement Plants: Transporting limestone, aggregates, and clinker.
• Long-Distance Overland Conveying: Moving materials from a mine or quarry directly to a processing plant or railhead over many kilometers.
