Copper mines operate with long-distance conveyors, high working tensions and extremely abrasive materials. Copper ore with quartz and pyrite can destroy a conventional belt within weeks. Underground operations add the requirement for certified flame retardant belts.
At NFP Industrial we represent Zhejiang Fuda Rubber Co., Ltd., a reference supplier of belts for copper mining in Chile, Peru and Argentina, with international certifications and supply capacity for large-scale projects.
ST (steel cable) belts for copper mining
The Fuda ST range covers from ST630 to ST5400 N/mm, with steel cables of 3.0 to 11.3 mm diameter and widths of 800 to 2400 mm. Manufactured to DIN, ISO, RMA, CSA and AS standards.
| Model | Nominal tension | Cable diameter | Available widths |
|---|---|---|---|
| ST630 | 630 N/mm | 3.0–3.5 mm | 800–2000 mm |
| ST1000 | 1,000 N/mm | 4.0–4.5 mm | 800–2200 mm |
| ST1600 | 1,600 N/mm | 5.5–6.0 mm | 1000–2400 mm |
| ST2500 | 2,500 N/mm | 7.5–8.0 mm | 1200–2400 mm |
| ST3150 | 3,150 N/mm | 9.0–9.5 mm | 1200–2400 mm |
| ST5400 | 5,400 N/mm | 11.0–11.3 mm | 1600–2400 mm |
Special properties for copper mining
Flame retardant
Mandatory in all underground copper operations. Certifications: MSHA (USA), DIN-EN-14973 (Europe), CSA-M422-12 (Canada), AS4606 (Australia) and JIS-K-6324 (Japan).
Rip-stop
Transverse breakers of polyester, nylon or steel integrated into the carcass to stop the propagation of longitudinal tears caused by rock fragments with sharp edges.
Integrated integrity sensor
Induction loops vulcanised every 50–150 metres. When an object penetrates the belt and cuts the loop, the control system stops the conveyor automatically, preventing damage propagation and minimising downtime.
