Product Description

STEEL CORD CONVEYOR BELT

Product Classification

Steel cord conveyor belts are used for heavy-duty applications and can be classified by use, structure, and cord type. They come with different cover properties like heat resistance, fire resistance, oil resistance, cold resistance, and wear resistance. Common structures include single-layer and double-layer designs for high strength and long-distance transport. Special types like pipe belts help prevent material spillage. The cords can also be standard, flexible, or anti-corrosive to suit different working conditions.


Applications
Steel cord conveyor belt is widely used in coal, mine, port, metallurgy, electric power, chemical industry, and other fields. It is suitable for conveying massive, granular, and powder materials in high-strength, long-distance, and large-volume situations.

Structure
 

A steel cord conveyor belt is composed of several key layers: a wear-resistant top rubber cover, a high-strength steel cord layer that runs longitudinally for maximum tensile strength, core rubber that bonds and cushions the cords, a bottom rubber cover for underside protection, and optional edge rubber sealing. This robust structure provides excellent durability, flexibility, and resistance to impact, wear, and environmental factors-making it ideal for long-distance, heavy-duty applications in industries like mining, cement, and bulk material handling.

Production Process

 
The rubber conveyor belts may generally be produced in 5 steps.

Mixing → Calendaring →Molding → Vulcanization - Finished Belt


1. The initial phase of the production process is to mix the rubber.
2.  The calendering process mainly completes the fabric coating, cover sheeting, and bonding of the belt carcass and the covering sheet.
3.  Molding is the process of neatly adhering multiple layers of the belt together longitudinally, sticking edge rubber on both sides, and covering rubber on the top and bottom to make a belt blank.
4. Rubber vulcanization is one of the most important procedures in the processing of rubber conveyor belts, as well as the final step in the manufacturing process.
5. Finished belt after testing.
