These belts, available in steel cord and nylon varieties, maintain structural integrity and provide enhanced traction, ensuring smooth and efficient material transport even over extensive distances.

Product Highlights

Suitability for Long Distances and High Abuse Conditions

1. Design for Long-Distance Transport:

  • Structural Integrity: steel cord conveyor belts and nylon conveyor belts are designed to maintain structural integrity over long distances. The incorporation of steel cords or nylon fibers within the belt provides the necessary strength to support heavy loads without sagging or stretching.
  • Low Elongation: The low elongation property of these belts ensures minimal stretch, which is crucial for maintaining consistent belt length and performance over extensive distances. This characteristic is particularly important in applications where precise material handling is required over long conveyor routes.
  • Enhanced Belt Traction: The surface of these belts is engineered to enhance traction, reducing the risk of slippage during long-distance transport. This feature ensures that materials are conveyed smoothly and efficiently, even over extended runs.

2. High Abuse Conditions:

  • Impact Resistance: Both steel cold conveyor belts and nylon conveyor belts are designed to withstand high-impact conditions. The robust construction of these belts allows them to absorb and dissipate the energy from heavy impacts, such as falling rocks or heavy loads, without sustaining damage.
  • Abrasion Resistance: The outer layer of these belts is made from high-quality rubber compounds that provide excellent resistance to abrasion. This ensures that the belts can handle the wear and tear associated with rough and abrasive materials, prolonging their lifespan even in the most demanding environments.
  • Heat and Chemical Resistance: For applications involving high temperatures or exposure to chemicals, specialized versions of these belts are available. These belts are treated with heat-resistant or chemically-resistant compounds, allowing them to operate effectively in harsh conditions without degrading.

High Durability Due to Superior Splice Efficiency and Strong Bonding

1. Superior Splice Efficiency:

  • Advanced Splicing Techniques: The durability of steel cord and nylon conveyor belts is significantly enhanced by advanced splicing techniques. These techniques ensure a seamless and strong connection between belt segments, maintaining the integrity and strength of the belt throughout its length.
  • Long Splice Life: Superior splicing methods, such as vulcanization, create a splice that is as strong as the original belt material. This results in a longer splice life, reducing the frequency of splice-related maintenance and downtime.
  • Consistent Performance: Efficient splicing ensures that the belt performs consistently across its entire length, with no weak points that could lead to failure. This consistency is critical for maintaining high productivity and minimizing operational interruptions.

2. Strong Bonding:

  • Bonding Between Layers: The bonding between the various layers of the conveyor belt is crucial for its overall durability. In steel cord conveyor belts, the steel cords are firmly bonded to the surrounding rubber, creating a unified structure that resists delamination and maintains strength under high tension.
  • Enhanced Adhesion: The use of advanced adhesives and bonding techniques ensures that the layers of the belt adhere strongly to one another. This enhanced adhesion prevents the layers from separating under stress, which is particularly important in high-tension applications.
  • Durability Under Stress: The strong bonding within the belt structure allows it to withstand the stresses of continuous operation, heavy loads, and high speeds. This durability translates to longer belt life and reduced maintenance costs, making these belts a cost-effective solution for demanding industrial applications.
