Product Description
ST conveyor belt, or steel cord conveyor belt, is designed for high-strength applications, featuring steel cords embedded within the belt for exceptional tensile strength and durability, making it suitable for heavy-duty tasks and long-distance conveying.


Structure of Steel Cord Conveyor Belts
Arrangement of Steel Cords
At the heart of a steel cord conveyor belt is the arrangement of longitudinally placed steel cords, which are the main load-bearing elements. These cords are typically made from high-tensile steel and are laid out in a parallel formation. The number, diameter, and spacing of the steel cords can vary depending on the specific belt specifications and the intended use. This arrangement is crucial for providing the high tensile strength that is characteristic of these belts.
Coating and Embedding of Steel Cords
Each steel cord in the conveyor belt is coated with a special rubber compound, protecting against corrosion, ensuring a strong bond with the rubber, and evenly distributing load, a crucial factor in the belt's performance and longevity.
Top and Bottom Covers
The belt's core of steel cords and rubber is encased in top and bottom covers made of rubber or similar materials, offering extra protection against wear, tear, and environmental elements such as moisture, chemicals, and extreme temperatures.
Steel cord conveyor belt's Specification Explaination

Features
High tensile strength: The belts are suitable for large span, long-distance transportation of materials.
Small elongation in use: The belts need only a very short take-up stroke distance.
The small diameter of drive pulley: The belt body has a layer of longitudinally arranged steel cords as its skeleton, and thus is resistant to flex fatigue. Therefore, a drive pulley of smaller diameter can be used to make the equipment smaller.
High adhesion between rubber and steel cord: The steel cords are coated with zinc on their surface, and also the rubber used has the property of good adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop, so the rubber belts are long in life.
Even tension of steel cords: Because of 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 awry.
Good trough ability: As the belt body has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from escaping.
Inspection of the belt with X-rays: Users can use X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.
