Steel Cord Conveyor Belt

The steel cord conveyor belt consists of steel cord (ST800/ST/ST/ST/ST/ST/ST/ST etc.) and rubber covering,the production process includes steps such as steel cord weaving, rubber mixing, extrusion and vulcanization. Compared with EP conveyor belts, steel cord conveyor belts have higher tensile strength, abrasion resistance and corrosion resistance, more importantly, due to the super tensile strength of steel cords, they overcome the problems of easy deformation and overstretching of EP conveyor belts, so it is more suitable for long-distance, heavy-duty and high-speed transportation, widely used in mining industry, steel mill, seaports, building materials, metallurgy and other industries, especially in harsh environments and high-intensity working conditions.

With competitive price and timely delivery, suntay sincerely hope to be your supplier and partner.

Characteristics:

1. High tensile strength: The belts are suitable for large span, long-distance transportation of materials.

2. Small elongation in use: The belts need only a very short take-up stroke distance.

3. The small diameter of drive pulley: The belt body has a layer of longitudinally arranged steel cords as its skeleton, and thus is resistant to flex fatigue. Therefore, a drive pulley of smaller diameter can be used to make the equipment smaller.

4. High adhesion between rubber and steel cord: The steel cords are coated with zinc on their surface, and also the rubber used has the property of good adhesion with steel cords. Therefore, the rubber is tightly adhered to the steel cords and is resistant to shock and difficult to drop, so the rubber belts are long in life.

5. Even tension of steel cords: Because of advanced techniques in manufacturing, the steel cords are very evenly arranged and have the same tension, so the belts are well-balanced in running and difficult to run awry.

6. Good trough ability: As the belt body has no transverse skeleton, it is easy to form a deep trough, so the belts can load more materials and prevent the materials from escaping.

7. Inspection of the belt with X-rays: Users can use X-rays to inspect damages of the skeleton steel cords on the conveyor machines to prevent accidents from happening.

Steel cord conveyor belt specification:

Steel cord is the core component of steel cord conveyor belts, providing the strength and stability necessary to withstand high tension and repeated pulling forces. SUNGDA’s steel cord utilizes Contitech’s specialized “HIXIH” brand high-strength steel cord, enabling SUNGDA’s series of steel cord conveyor belts to meet the demands of long-distance, high-strength, and various adverse operating conditions. The steel cord has the following advantages:

1.Zinc Galvanized and High Tension Open Type Steel Cord

Sungda selects its cord construction to provide the best specifications for particular applications. The cords are constructed to offer high flexibility, low elongation, and efficient, high-strength splice designs. The galvanized zinc coating serves as a bonding agent between the steel cord and skim rubber, providing a crucial barrier against corrosion.

2.Limited Take-up Travel

Sungda belts elongate a maximum of 0.25% at rated tension. This allows for lower-cost take-up systems on many applications, making Sungda the preferred choice for long overland and short stacker/reclaiming systems where minimum elongation is critical.

3.Long Splice Life:
Our proven splicing methods, validated by dynamic splice testers, result in dynamic splice efficiencies exceeding the 50% rating defined in DIN Part 3. With proper technique, splices on Sungda belts should last the life of the belt.

4.High Impact Resistance

Advanced cover compounds and skim rubber with superior adhesion combine to provide the impact, tear, and rip resistance demanded by your applications.

5.Lower Cost-per-Ton

Fewer conveyors and splices, shorter take-ups, and reduced belt inventory lead to longer belt life, longer splice life, and reduced downtime. All these factors contribute to a lower cost-per-ton of material conveyed, making a significant improvement in your bottom line.

Industrial uses of Conveyor belts

Before the advancement in technology, labor was used to transport material and goods in the manufacturing industry. People were responsible for carrying these products from one place to another using some kind of mobile transportation device. This method of transportation was susceptible to a number of risks namely deterioration of products, miss handling and many more.
However, with the developing technology new and better ways of transporting goods were developed. Among these new methods, conveyor belt system is the most cost-effective method of transporting goods and materials in the manufacturing industries. Physical labors require manpower which increases the liabilities. The conveyor belts have the ability to reduce the need for physical labor, eliminating the wages and increases the profit of the company. Due to their massive success, virtually every industry has started to incorporate this amazing system in their transportation regime.

Conveyor belts are divided into two main categories namely Steel cord belting and Fabric belting. They might have identical external features, but their internal structure differs. In Fabric belt, the inner layer that is made up of plastic web, cotton or mesh provides the tensile strength of the belt. On the contrary, a series of steel cables are a part of the steel cord belts. This series of steel belts are separated via a rubber. Different kinds of belts are used for different types of application. For example, the steel belts are used on escalators, moving sidewalks and similar manufacturing procedures.

Industrial uses of Conveyor belts

Conveyor belts are the types of belts that are suspended with a continous loop of material that moves around them.  They are used in a number of applications in the food processing, manufacturing and other heavy industries. Industries where these conveyor belt systems are excelling and they include automotive, computer, good, packaging, print finishing, bottling and canning, chemical, pharmaceutical, aerospace and food processing.

A number of things are being transported using these convey belts, but the most common include food items such as nuts and beans, grain and animal feed, wood and furniture, pills and powders, scrap and metal and automotive components.

Why use conveyor belt systems

Use of conveyor belt systems offers a number of benefits, some of which are listed below.

  • They have the ability to transport material safely from one place to another.
  • They are better and safer than forklift and they can be installed anywhere.
  • They are built in such a manner that they can move loads of all weights, sizes, and shapes.
  • Many of the conveyor systems come with in built security measure in order to reduce risk factor.

Conveyor belt system is the modern, effective and better way of transporting materials and good from one place to another. They are risk-free and can be easily installed almost anywhere. They are the perfect solution for all your transportation problems.
