Steel Cord Conveyor Belt Overview

ZOOMRY steel cord conveyor belts are high-tension heavy duty conveyor belts engineered for long-distance, high-capacity bulk material conveying. Available in strength classes from ST630 to ST4000 with tensile strength up to 4,000 N/mm, these belts use longitudinal steel wire ropes to provide low elongation and stable operation in demanding mining conveyor, cement, port, power, and metallurgy applications.

As a bulk material handling equipment manufacturer, ZOOMRY supplies steel cord belts as individual replacement belts and as part of complete long-distance conveyor, curved conveyor, mine trunk conveyor, stockyard, and port handling projects. Belt width, cover grade, cord construction, and splice design are configured according to conveyor calculations and operating conditions.

Project Reference: Wuxue Southeast Mining

8,617 m Long-Distance Curved Conveyor with ZOOMRY Steel Cord Belt

ZOOMRY supplied the steel cord conveyor belt for the Wuxue Southeast Mining long-distance curved conveyor project. The system has an 8,617 m conveying route and a rated capacity of 2,500 t/h, operating under continuous bulk material transport conditions.

The steel cord belt configuration was selected around conveyor tension, curved route geometry, material duty, drive arrangement, pulley design, and hot-vulcanized splicing requirements.

Why Choose a Steel Cord Belt

High Tensile Strength

Longitudinal steel cords provide strength for high belt tension, long routes, and high-capacity systems.

Low Elongation

Low working elongation supports stable take-up performance on long-distance routes.

Heavy-Duty Construction

Cord construction and cover compounds selectable for abrasive, high-impact, wet, or hot conditions.

Project-Specific Engineering

Belt construction, covers, and splice layout selected around actual conveying duty.


Typical Steel Cord Belt Applications

  • Mining Conveyors: Long-distance transport of iron ore, copper ore, coal, bauxite, and other bulk materials.
  • Cement and Quarry: Quarry-to-plant limestone, crushed aggregate, and raw material handling.
  • Ports and Terminals: Stockyards, receiving hoppers, transfer towers, and ship loader connections.
  • Power Plant Fuel: Coal yard, biomass, and bulk fuel conveying systems.
  • Metallurgy and Heavy Industry: Sinter, coke, pellets, ores, and high-temperature materials.

Splicing, Packaging, and Delivery

  • Splicing Support: Hot-vulcanization splice details and technical guidance for the selected belt construction.
  • Packaging: Belt rolls, reels, and shipment packaging arranged according to belt dimensions and transport method.
  • MOQ and Delivery: Depends on belt class, width, cover grade, total length, inspection requirements, and destination.
  • Documentation: Product specifications, quality records, and compliance documents confirmed in quotation.

Steel Cord Belt Specifications: ST630–ST4000

ZOOMRY supplies steel cord conveyor belt strength classes from ST630 to ST4000. The following table is an initial selection guide:

Belt Class Tensile Strength Typical Belt Width Typical Application
ST630 630 N/mm 650–1,400 mm Medium-duty mining and quarry conveyors
ST800 800 N/mm 650–1,600 mm Longer plant conveyors and higher-tension routes
ST1000 / ST1250 1,000–1,250 N/mm 800–1,800 mm High-capacity mine, coal yard, and port conveyors
ST1600 / ST2000 1,600–2,000 N/mm 1,000–2,200 mm Overland and high-lift conveyor systems
ST2500 / ST3150 2,500–3,150 N/mm 1,200–2,400 mm Long-distance, high-tension mining routes
ST4000 4,000 N/mm Project-specific Maximum-tension special projects

Final belt construction is confirmed after reviewing the complete conveyor design including tension calculation, pulley diameter, and material data.

Steel Cord Conveyor Belt FAQ

Q: What steel cord belt strength do I need?

The correct strength class is determined by conveyor tension calculations. Conveyor length, lift height, material load, belt width, belt speed, and drive arrangement must be evaluated before selecting ST630, ST1000, ST1600, ST2500, or ST4000. Share your conveyor parameters for a specific recommendation.

Q: How is a steel cord conveyor belt different from a fabric belt?

Steel cord belts use longitudinal steel wire ropes as the primary reinforcement, providing high tensile strength and low elongation. Fabric belts use textile plies (EP or nylon) and are typically selected for moderate distances and smaller pulley diameters. For heavy-duty mining and long-distance conveying, steel cord belts are generally preferred.

Q: What cover grades are available for heavy duty conveyor belts?

Available cover options include standard rubber, abrasion-resistant (DIN Y/Z), heat-resistant (T1/T2/T3), flame-retardant (ISO 340), cold-resistant, and oil/chemical-resistant compounds. Cover selection depends on material type, temperature, abrasiveness, and environmental conditions.

Q: Can the belt be supplied with a complete conveyor system?

Yes. ZOOMRY can supply steel cord conveyor belts as part of an integrated bulk material handling solution including conveyors, pulleys, idlers, drives, and project engineering support.
