Ultra High Strength Material Conveying Solutions for the Mining Industry
In the mining industry, material conveying systems are the "arteries" of production. In the face of increasingly harsh mining conditions in coal, copper, iron and gold mines, traditional Mining Steel Cord Conveyor Belts are often difficult to meet the multiple challenges of high strength, long distance and impact resistance. The high-strength steel cord conveyor belts we provide you are premium conveyor belts designed to solve these pain points.
Product Overview
Our Mining Steel Cord Conveyor Belt is made of high strength steel wire rope as the skeleton material, adopting unique open wire rope structure and advanced formula design, and vulcanized by cold press molding plus core rubber and cover rubber. The maximum strength of the product can reach ST10000, which represents the top technical level of the industry.
Core Advantages
Ultra-high tensile strength
Up to ST10000, easy to cope with the challenge of high intensity.
Ultra-low elongation
Only 0.25% elongation under rated tension, shorter tensioning stroke.
Superior Impact Resistance
Unique structural design, excellent impact resistance.
Intelligent protection
Optional coil anti-tear monitoring system.
Three Core Performances for Mining Applications
Our wire rope core conveyor belts are made of galvanized open steel wire ropes with high elasticity and low elongation, and at the same time, they are tightly bonded with the core rubber to form a rust-resistant and corrosion-resistant protective layer. The product has been tested in dynamic fatigue joints by the University of Hannover, Germany, and has excellent performance.
Strength class | Applicable scenarios | Core advantages
ST6300-S10000 | Mainline for mega mines | Top strength class in the world to cope with the toughest working conditions
ST4000-ST5400 | Large and medium-sized mines | Mainstream choice for stable and reliable performance
ST500-ST3500 | Small and medium-sized mines/branches | Best price/performance ratio
The elongation of the conveyor belt has a direct impact on the system design and operating costs for conveyor lines in mines that are often several kilometers or even tens of kilometers in length.
The advantage of low elongation is obvious:
Maximum elongation of 0.25% at rated tension, much better than ordinary products.
Significantly reduce the tensioning system investment and operating costs
Reduction of intermediate transfer stations, realizing the true meaning of "one line direct".
In a Coal Mine in Australia, our ST2500 width3200 conveyor belt runs stably with an amazing capacity of 11,000 tons/hour (equivalent to the synchronous operation of more than 300 heavy-duty trucks), and the difference in the height of the lower conveyor belt reaches 566 meters, which creates a world-class record.
Ores from coal, copper, iron and gold mines are often sharp-edged and huge in mass, which pose a high risk of impact and tearing to conveyor belts.
Our solution:
The cover rubber is tightly bonded to the core rubber, resulting in excellent impact and tear resistance.
Optional transverse reinforcement as tear-resistant layer prevents tearing from expanding in the event of puncture by sharp objects.
Open cross-twisted wire rope design ensures thorough penetration of the core adhesive and strong bonding.
In practical application, the product can maintain excellent performance in the environment from -45℃ to extreme cold, and the cover layer has the characteristics of anti-cutting, abrasion resistance and corrosion resistance.
