Steel Cord Conveyor Belt
Application
They are widely used in coal mining, port, power plant, tunneling, metallurgy, chemical industry and constructionindustry, etc.
 
Features
  1. High tensile strength:steel cord conveyor belt is suitable for transferring materials with long distance, high intensity and large load.
  2. Small diameter of driving pulley: the belt body has a layer of longitudinally arranged steel cords as its carcass to resistant to flex fatigue. Therefore, driving pulley with smaller diameter can be used to make the equipment smaller and reduce energy consumption.
  3. Small elongation in use: a very short take-up stroke distance needed.
  4. Even tension of steel cords: thanks to our advanced techniques in manufacturing, the steel cords are very evenly arranged with the same tension, so the belts are well balanced in running and difficult to run away.
