Aplication
Application: Tear Resistant Steel Cord Conveyor Belt can be widely used for material transportation in coal, mining, port, metallurgy, electric power, chemical industry and other fields.
Features: high tensile strength, good impact resistance, long service life, low elongation, good trough formation, good bending resistance, suitable for long-distance, large-volume, high-speed material transportation.
The anti-tear steel wire rope core conveyor belt is provided with high-strength steel wire ropes or high-strength and high-strength chemical fiber ropes that are uniformly arranged horizontally above (or up and down) the steel rope core as the anti-tear layer, and the anti-tear layer is perpendicular to the running direction of the conveyor belt. When the conveyor belt conveys hard and sharp materials, the tear-resistant layer can prevent the sharp and hard objects from being pierced, and once pierced, it can also generate enough resistance to resist the sharp and hard objects tearing the tape, thereby effectively preventing the tearing of the conveyor belt.

★The quality of the tape varies according to the thickness and density of the tape cover glue, core glue.
Note: The length of a single roll of conveyor belt is generally 200m, and the length of the roll is more than 200m, which is determined by the negotiation between the supplier and the buyer.
