Steel Cord Conveyor Belt
Application
Steel cord conveyor belts are suitable for high strength, long distance, and heavy load transportation of materials, which are widely used in coalmines, mines, ports, metallurgy, power plant, chemical industries, etc.
Characteristics
1. High tensile strength: The belts are suitable for large span, long distance transportation of materials.
2. Small elongation in use: The belts need only a very short take-up stroke distance.
3. Small diameter of drive pulley: The carcass has a layer of longitudinally arranged steel cords as its skeleton,and thus is resistant to flex fatigue. Therefore, drive pulley of smaller diameter can be used to make the equipment smaller.
4. High adhesion between rubber and steel cord: The steel cords are zinc coated, the intermediate rubber used also has good adhesion property with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop,thus the rubber belts are long in service life.
5. Even tension of steel cords: Out of our advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well balanced in running and difficult to run deviation.
6. Good troughability: As the belt body has no transverse skeleton, it is easy to from a deep trough, so the belts can load more materials and prevent the materials from escaping.
