Steel Cord Conveyor Belt
General steel cord conveyor belt
The steel cord conveyor belt can be used to a wide range of applications such as coal, mining, port, metallurgy, electricity, chemical industry and so on.
Structure
The carcass consists of the evenly arranged, left and right twisted galvanized steel cords and the core rubber with high adhesion properties. The top and bottom rubber are covered on the carcass to form the conveyor belt.
Details
- ST series
- GX series
- Steel cord structure
Features
- High tensile strength. Long service life. Low elongation allows short take-up strokes. Good troughability. Ideal for long-distance, large-capacity and high-speed transportation of materials.
- The core rubber can fully permeate into the cords to achieve high adhesion properties between the rubber and steel cords.
- Good rust resistance of steel cord.
- Mutual shearing and twisting of steel cords are relived and resistant to dynamic fatigue to extend the service life of the steel cord conveyor belt.
Transverse reinforced steel cord conveyor belt
Structure: on the side or sides perpendicular to the steel cord, transversely arrange steel cords, steel wire cord, fiber cord, fiber fabric or other reinforcement layer.
Features: good shock resistance and tear resistance.
