Steel core conveyor belt
Summary:
The steel conveyor belt is composed of rubber core, wirerope, coating and edge adhesive. It has the advantages of high tensile strength, good impact resistance, long service life, little elongation, so these belts are widely used in conveying materials for long distance, big volume and high speed.
Usage:
These steel belts are usually used in coal industry, iron ore industry, metallurgy industry and chemical industry.
Features:
1, These steel core conveyor belt has Little elongation;
2,High tensile strength and security coefficient;
3,Wirerope and rubber strongly combines together;
4,Good impact resistance and fine joint, long service life.
Performance of steel core conveyor belt :
1,All the performances accord with the standard of GB9770 or customize the parameters of the rubber layout with customers;
2,IF anti-impact and resistant tearing steel core conveyor belt be chosen, the shock resistance will be raised 1-2 times as the usual mode, and the tear resistance will be raised 0.5-1 times as the usual mode.
3,The lowest working temperature of The steel core conveyor belt of cold tolerance mold is minus 60°C.
Production standard:
These steel conveyor belt are produced not only with the standard of Chinese GB/T9770,but also with the standard of German DIN22131,Japanese JISK6369 and Australian AS1333.If these belt are used in mine ,it may be has the advantage of anti-flame, we will produce it according to the standard of MT668-1997. If any other requirements, we will consult the actual process with customers.
