Jinflex Steel Cord Conveyor Belt Achieves Three-Year Zero-Failure Operation in Indonesian Nickel Mine

In a large nickel mining project located in Sulawesi, Indonesia, the 4.8 km overland conveyor system equipped with Jinflex ST2500 steel cord conveyor belts has maintained uninterrupted operation for more than three years since commissioning in October 2022, achieving zero unplanned replacements and zero longitudinal tears under extreme tropical conditions.

Operating 24/7 in an environment with annual rainfall exceeding 3,500 mm, ambient temperatures between 28–38 °C, and frequent impact from sharp laterite nickel ore at a throughput of 2,800 tons per hour, the conveyor line has transported over 28 million tons of material to date. Throughout this period, belt elongation has remained below 0.18 %, cover rubber wear is minimal, and regular electromagnetic inspections show no signs of steel cord corrosion or breakage. The customer reports that maintenance costs reduced by more than 40 % compared to previously used European brands, while overall transport efficiency has increased significantly due to stable tension and virtually zero belt-related downtime.

The outstanding performance is attributed to Jinflex’s high-adhesion core rubber, heavily galvanized steel cords with superior corrosion resistance, and a specially formulated heavy-duty cover compound optimized for high-humidity and sharp-material applications, combined with an embedded breaker fabric that provides exceptional impact and tear protection.

This project has become a benchmark for long-distance, heavy-duty steel cord conveyor belt applications in Southeast Asia’s tropical mining sector. Similar reliable, long-term performance has also been recorded in major copper mines in Chile, iron ore export terminals in Brazil, and large coal operations in Australia.

Customers worldwide continue to choose Jinflex steel cord conveyor belts for critical conveying systems where maximum uptime and lowest total cost of ownership are essential.
