Steel Cord Conveyor Belt
Application
- Steel Cord Conveyor Belts are widely used in distributed occasion, cement, coal mines, quarries, mining, power plants, metallurgy, ports and chemical industry, etc.
Advantage
- High tensile strength, low elongation values, impact resistance and good troughability. Available for long-distance, large capacity, high-speed transmission of massive, granular and powder materials.
- More flexible than their equivalent with fabric reinforcement and requiring drums with smaller diameters.
- Using zinc galvanized open steel cord and rubber with property of good adhesion, then the adhesion between steel cord and rubber is tight. And belt is resistant to impact and having longer using life.
- With advanced manufacturing techniques, steel cords are evenly arranged with the same tension. Therefore, belts can run well and difficult to run away.
- Limiting of longitudinal cuts and tears with one or two layer of steel cord tensioning according to customers' special requirement.
