steel-cord conveyor belt
peculiarities: Large tensile strength, long service life, small used elongation, good property of forming groove and bend-resistant. It is suitable for the transportation of materials with long distance, longterm irregularity travel and high speed. It is consisted of core rubber, steel wire, cover and edge rubber.
application: Widely used in coal, mine, port, metallurgy, electricity, chemicals to transport materials.
variety:
Divided by the property of cover coat: common steel-cord conveyor belt, burn-resistant steel-cord conveyor belt, heat-resistant steel-cord conveyor belt, wear-resistant steel-cord conveyor belt, cold-resistant steel-cord conveyor belt, acid and alkali-resistant steel-cord conveyor belt, oil-resistant steel-cord conveyor belt, burn-resistant steel-cord conveyor belt, etc.
