Mining is one of the most demanding environments for a conveyor belt: extreme loads, abrasive materials, kilometres of transport distance, underground operation with ignition risk, and variable temperatures. A belt failure in a mine can mean production stoppages costing thousands of euros per hour.
At NFP Industrial we represent Zhejiang Fuda Rubber Co., Ltd., a manufacturer specialised in rubber belts for mining with over 35 years of experience, 10 invention patents and exports to more than 60 countries.
Specialised pages by type of mining
Copper
High-tension ST belts for copper mines in Chile and Peru. Flame retardant and rip-stop.
Lithium
EP and NN belts for Atacama and Antofagasta salt flats. Resistance to extreme conditions.
Aggregates and quarries
High-abrasion grade D and chevron for quarries and cement plants in Spain.
Recommended belts for mining
Steel cable belts (ST)
For long-distance, high-tension transport. The Fuda range covers from ST630 (630 N/mm) to ST5400 (5,400 N/mm), with widths of 800 to 2400 mm and steel cables of 3.0 to 11.3 mm diameter. Manufactured to DIN, ISO, RMA, CSA and AS standards.
Flame retardant belts
Mandatory in underground mining. Special formula and carcass treatment for transport of flammable materials. Certifications: MSHA, DIN-EN-14973, CSA-M422-12, SABS, AS4606, JIS-K-6324.
Rip-stop belts
Steel cable carcass with transverse breakers (polyester, nylon or steel) that prevent the propagation of longitudinal tears if a sharp object penetrates the belt.
Belts with integrated sensor
Induction loop system vulcanised inside the belt. If a foreign body cuts the loop, the receiver detects the signal loss and stops the drive automatically. Recommended distance between loops: 50–150 metres.
Pipe (tubular) belts
For sealed transport on inclines without material spillage. Compatible with grade D (high abrasion), H (rip-stop) and T1/T2 (high temperature) covers. Tube diameters from Ø100 mm to Ø600 mm.
Cover grades for mining
| Grade | Application | Tensile strength | Abrasion |
|---|---|---|---|
| D (high abrasion) | Abrasive minerals | ≥ 18 MPa | ≤ 160 mm³ |
| H (rip-stop) | Sharp materials | ≥ 20 MPa | ≤ 150 mm³ |
| L (general use) | General mining | ≥ 14 MPa | ≤ 200 mm³ |
| T1 (heat ≤100 °C) | Hot minerals | ≥ 10 MPa | ≤ 200 mm³ |
