Product Description

Steel cord conveyor belts are widely employed in high-strength, long-distance, and heavy-load material transportation systems, as well as specialized applications necessitating high-strength, short-distance material conveyance.

Features:
1. High tensile strength for large-span, long-distance material transport.
2. Minimal elongation, requiring short take-up stroke distance.
3. Compact drive pulley design with steel cord skeleton for reduced equipment size.
4. Superior rubber-steel cord adhesion with zinc-coated cords for extended belt life.
5. Precision-engineered steel cord tension for balanced operation.
6. Excellent troughability with transverse-free design for increased material capacity.
7. Integrated steel cord inspection system for enhanced safety.
