Steel Cord Conveyor Belt

Picture4

Advantage

Ability to withstand high tensile strength, low elongation, impact resistance and good trough ability.
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.

Characteristic

Better flexure than the multi-ply fabric belt with the same strength.

Smaller diameter for the required pulley.

Using galvanized open steel cords and rubber materials provides good adhesion properties, and good bond between the steel cord and core rubber.

Results in a high impact resistance and durable belt.

Using advanced manufacturing techniques, the steel cords are evenly arranged at the same tension.
Smoothening belt running and increasing drift avoidance.

One or two layers of anti-tear materials are added to the products according to customer’s special request in order to decrease the possibilities of tear within longitudinal range.
