Steel cord conveyor belts (ST800/ST1000/ST1250/ST1400/ST1600/ST1800/ST2000/ST2250 etc.) are widely used in high strength, long distance and heavy load transportation of materials, and they are also used in high strength and short distance transportation of materials on special occasions.

SUNGDA Conveyor Belt, part of the same group as JIENASI, is one of the largest steel cord conveyor belt manufacturers in China, boasting 22 state-of-the-art production lines. It utilizes "HIXIH" steel cords, the same brand used by Continental steel cord conveyor belts, combined with high-tensile, wear-resistant premium vulcanized rubber. This ensures exceptional performance in long-distance transportation, high-capacity conveying, and extreme operating conditions.

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 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.

4. 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.

5. 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.

6. Good trough ability: 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.

7. 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.

Steel cord conveyor belt’s key to symbol:

Compared with EP conveyor belts, steel cord conveyor belts are more complicated in the manufacturing process, which is mainly due to the following three reasons:

• Steel cord rope weaving: The core of the steel wire rope conveyor belt is made of multi-layer steel cord rope weaving, manufacturers are required to master professional weaving technology to ensure the tight connection and uniform distribution of steel wires.

• Rubber extrusion: The steel cord core needs to be covered by rubber, which requires rubber mixing and extrusion technology, manufacturers need to master the reasonable formula and extrusion process of rubber to ensure the uniformity and adhesion of the rubber covering layer.

• Forming and vulcanization of the conveyor belt:The forming process requires equipment that can combine the steel cord core with the rubber covering layer well to form a strong conveyor belt structure, the vulcanization process requires control of parameters such as temperature, pressure and time to ensure that the tape achieves the desired physical properties.

Since the manufacturing process of the steel cord conveyor belt is more complicated, the manufacturer is required to have very strong technical strength and a more advanced vulcanization production line, and have strict quality control processes before, during and after production, only advanced equipment and professional With a professional technical team, the manufacturer can ensure the production of high-quality wire rope conveyor belts to meet the needs of customers
