1600mm,2000mm, 2200mm, 2400mm;

Thickness: such as 3+1.5mm, 3+2mm, 4+2mm, 5+3mm, 6+2mm, 8+2mm etc

Usage

Steel cord conveyor belts are suitable for high strength, long distance, and heavy load transportation of materials, which are widely used in coalmines, mines, ports, metallurgy, electricity, chemical industries, etc.

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 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 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. Good troughability: 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.
8. 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.




 Standard Specifications


The values will help to determine the appropriate cover compound for the application or for the materials carries. Reliable assessment of the behavior of the covers in service for wear and cut resistance cannot be determined from tensile strength, and abrasion values alone.
Features: high tensile strength, low extensibility, small used transmission pulley diameter, uniform steel wire rope
tension, excellent troughbility and good adhesive between rubber and steel wire.
Applicable environment: The belt realizes conveying a large amount of materials at long distance and at high speed in the fields of coal, mine, ports, metallurgy, electric power, chemical engineering, etc.
Technical data: The steel cord conveying belt has the general used, high abrasion, cold-resistant and flame-retardant according to the using requirement and the performance of the cover rubber.
