Steel Cords for Mining and Quarrying Conveyor Belts

Steel cords are a critical component in the construction of steel cord conveyor belts, providing the high tensile strength and durability necessary for heavy-duty and long-distance conveying applications. If a mobile conveyor is used for transporting large amounts of materials, a conveyor belt with steel cords is also required. Here's a detailed look at the steel cords used in conveyor belts:

Characteristics of Steel Cords

Material

Made from high-carbon steel, which offers excellent tensile strength.
Often galvanized or coated to prevent corrosion and enhance longevity.

Construction

Conveyor Belt steel cords are typically constructed by twisting together multiple strands of steel wire.
The most common constructions are 7x7, 7x19, or 19x7, indicating the number of wires in each strand and the number of strands twisted together.

Diameter

The diameter of steel cords can vary widely, depending on the required strength and the belt's intended application.
Common diameters range from 1 mm to 12 mm.

Spacing

Cords are evenly spaced within the belt to ensure uniform strength and flexibility.
The spacing is determined based on the belt's load capacity and operational requirements.

Benefits of Using Steel Cords in Conveyor Belts

High Tensile Strength:
Steel cords provide the highest tensile strength of any carcass material, making them ideal for transporting heavy loads over long distances.
Low Elongation:
Steel cords have minimal stretch, which ensures the belt maintains consistent performance, alignment, and tracking.
Flexibility:
Despite their high strength, steel cords maintain good flexibility, allowing the belt to bend around pulleys and conform to various conveyor designs.
Durability:
High resistance to impacts, cuts, and abrasions extends the belt's lifespan and reduces maintenance costs.
Corrosion Resistance:
Galvanized or coated steel cords offer excellent resistance to corrosion, enhancing performance in harsh environments.

Steel cords are integral to the strength and durability of conveyor belts used in heavy-duty and long-distance applications. Their high tensile strength, low elongation, and resistance to wear and corrosion make them ideal for demanding industrial environments. Proper selection, maintenance, and inspection of steel cord conveyor belts are crucial for ensuring efficient and reliable material handling operations.
