ST-630 Steel Wire Conveyor Belt: A Powerful Solution for Heavy-Duty Material Handling

What is an ST-630 Steel Wire Conveyor Belt?

The "ST" designation signifies that this belt utilizes a steel wire core, renowned for its exceptional strength and durability, while “630” is a reference to the belt's rated tensile strength of 630 N/mm. The ST-630, belonging to the steel cord conveyor belt family, is engineered for high-strength, long-distance, and high-volume material conveying.

Why Choose a Steel Wire Core?

Steel wire conveyor belts offer significant advantages over fabric core belts, particularly in demanding environments. They boast higher tensile strength (with the ST series capable of reaching up to 8400 N/mm, even exceeding 10000 N/mm if needed), allowing them to handle heavier loads over longer distances. This high strength also translates to a lower safety factor (6-7, compared to 10 or more for fabric belts), potentially reducing initial investment costs.

Key Features and Benefits of the ST-630:

• High Strength and Durability: The ST-630 is built to withstand rigorous conditions. Its steel wire core, specially treated for high tensile strength and flexibility, ensures long-lasting performance.

• Excellent Troughability: The belt's design, without a transverse skeleton, allows it to form a deep trough, maximizing load capacity and preventing spillage.

• Low Elongation: With a maximum elongation of only 0.25% under rated tension, the ST-630 minimizes the need for extensive take-up systems, saving on space and costs.

• Superior Joint Strength: The ST series boasts joints that can match the belt's own tensile strength and lifespan, as proven by dynamic testing under DIN22131-3 standards.

• Corrosion Resistance: The galvanized, open-structured steel wires are embedded in a specialized core rubber, ensuring a strong bond and protection against rust.

Is the ST-630 the Right Choice for My Application?

If you're dealing with heavy loads, long distances, and require high-speed conveying, the ST-630 is likely an excellent fit. It's particularly well-suited for industries like:

• Mining: Transporting coal, ore, and other raw materials.

• Ports: Loading and unloading ships efficiently.

• Metallurgy: Handling heavy materials in steel plants.

• Power Generation: Conveying coal and other fuels.

Common Questions:

• Q: What is the lifespan of an ST-630 belt?

• A: The ST-630 is designed for long life. With proper maintenance, and thanks to its strong steel wire core and durable joints, it can provide years of reliable service. The precise lifespan will depend on the specific operating conditions.

• Q: How are the joints of the ST-630 made?

• A: The ST-630 utilizes a hot vulcanization process. This involves a meticulous process of preparing the belt ends (including cleaning with 120# gasoline), precisely arranging the steel wires, applying specialized rubber compounds (cover rubber, core rubber, and rubber paste), and using a vulcanizing machine to apply heat and pressure (up to 1.5 MPA) for a secure and durable bond.

• Q: What temperature can the ST-630 withstand?

• A: While the "ST" designation typically indicates high-temperature resistance, the specific temperature rating for the ST-630 would need to be confirmed with the manufacturer. For extremely high temperatures, other ST models, like the ST800, are designed for up to 800°C.

• Q: How does it compare to EP or NN belts?

• A: EP belts use a polyester/nylon core, while NN belts use a nylon core. While suitable for some applications, they generally have lower tensile strength compared to steel wire core belts like the ST-630.

Conclusion:

The ST-630 Steel Wire Conveyor Belt offers a compelling combination of strength, durability, and efficiency. Its robust construction, coupled with its ability to handle demanding applications, makes it a valuable asset in various heavy industries. If you're looking for a reliable solution for your material handling needs, the ST-630 is definitely worth considering.
