Steel cord conveyor belt

图片36.jpg

The steel cord conveyor belt is a rubber conveyor belt with steel cord as its skeleton. It has the advantages of high tensile strength, good impact resistance, long service life, small use elongation, good groove forming and good flex resistance. Suitable for long-distance, large-capacity and high speed transportation of materials.


Application

Commonly used in cement industry, coal mines, quarries, minings, electric power plants, metallurgic industry, ports and chemical industry, etc.


Advantage

High tensile strength, low elongation values, impact resistance and good troughability. Available for long-distance, large capacity, hight-speed transmission of massive, granular and powder materials.

●More flexible and requiring drums with smaller diameters.

●Using zinc galvanized open steel cord and rubber with property of good adhesion, then the adhesion between steel cord and rubber is tight. And belt is resistant to impact and having longer using life.

●With advanced manufacturing techniques,steel cords are evenly arranged with the same tension. Therefore , belts can run well and be difficult to run away.

●Limiting of longitudinal cuts and tears with one or two layers of steel cord tensioning according to customer special requirement.


Type

Conventional, Fire Resistance, Conventional Fire Resistance, Heat Resistance, Abrasion Resistance, Heat & Abrasion Resistance, Acid & Alkali & Oil Resistance, Cold Resistance, Ozone Resistance.


Standards

Strict implementation of international standards: GB/T, DIN, AS, SABS, RMA, BS, JS etc.
