Product Description
Steel cord conveyor belt are a type of conveyor belt that is ideal for transporting materials with high strength, heavy loads, and over long distances. Due to their properties, they are widely used in various industries such as coalmines, mines, ports, metallurgy, electricity, and chemical industries.
In the coalmining industry, steel cord conveyor belt are commonly seen in transportation systems that move coal from one place to another. This is due to the high strength of the steel cord, which makes it capable of withstanding the weight of the coal and the long distances it needs to travel.
In the metallurgy industry, steel cord conveyor belt are utilized in the transportation of iron ore and other materials that are used in steel production. The use of these belts helps to minimize downtime and increase productivity due to their strength and ability to transport heavy loads over long distances.
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 to make the equipment smaller.
4. High adhesion between rubber and steel cord: The steel cords are coated with zinc on their surface, and also the rubber 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 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 carcass 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.
7. Inspection of the belt with X-rays: Users can take X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.
