STRUCTURE
Please visit our website for more information on this topic.
Steel cable rubber conveyor belts are commonly used for transport of products at lengthy ranges and heavy loads which have high resistance. The steel cable conveyor belts are used also in high-speed transport at brief distances. These conveyor belts need only a very short take-up stroke.
The belt structure with its longitudinally ordered steel cables skeleton is resistant to fatigue because of flexing.
Thus, smaller diameter drive pulleys can be used to design equipment of smaller size. The steel wires are bonded with high level of adhesion to the fabric on their ground.
The rubber of the rubber conveyor belt with steel wires is therefore firmly attached to the steel cables and shockproof, enhancing the belt life. Steel cables are structured uniformly and have the same strain, which makes the belt upright and functional.
As the carcass doesn't have longitudinal yarns, the steel wire rubber conveyor belt carry more stuff within greater inclination.
CORD STRUCTURE
7×7 : Applied to low tension lines
7×19 : Applied to high tension lines used.
Features: high tensile strength, low extensibility, small used transmission pulley diameter, uniform steel wire rope
tension, excellent troughbility and good adhesive between rubber and steel wire.
Applicable environment: The belt realizes conveying a large amount of materials at long distance and at high speed in the fields of coal, mine, ports, metallurgy, electric power, chemical engineering, etc.
Technical data: The steel cord conveying belt has the general used, high abrasion, cold-resistant and flame-retardant according to the using requirement and the performance of the cover rubber.
