Unlike standard industrial belts that fail in 6-8 months, its mining-specific design withstands impact from 50kg ore lumps and resists oil, acid, and cut damage. It is widely used in open-pit mines, underground mines, and mineral processing plants, supporting long-distance transportation (up to 2000 meters) with stable operation.
Impact-Resistant Rubber Cover: Top cover thickness of 6-12mm (natural rubber + SBR blend) with shore hardness 65-70A, absorbing impact from falling ore. In a copper mine, it reduced belt punctures by 80% compared to standard 3mm cover belts. The bottom cover (4mm thickness) resists abrasion against rollers, with wear rate < 0.5mm/year.
High Tensile Reinforcement: Steel cord or EP (ethylene propylene) canvas reinforcement options. Steel cord variants handle tensile force up to 5000 N/mm, suitable for 2000-meter long-distance conveyors; EP canvas (EP200-EP400) is ideal for medium-length (500-1000m) systems with lower tension. Reinforcement layers are bonded via heat-press technology for 0% delamination rate.
Anti-Skid & Anti-Static Design: Diamond or chevron surface pattern increases friction coefficient to 0.8, preventing material slippage on 30° inclines. Static dissipation rate < 10⁸ Ω ensures safety in coal mines (complying with MT 914-2008 standards). Conductive rubber strips embedded every 500mm eliminate electrostatic buildup.
Weather Resistance: Operates stably in -40°C to 80°C temperatures. In Siberian open-pit mines (-35°C winter), it maintains flexibility without cracking; in Australian desert mines (75°C summer), rubber cover does not soften or deform. UV-resistant coating extends service life by 40% in outdoor applications.
Open-Pit Mining: Overland transportation of iron ore and bauxite. A Brazilian iron ore mine used 1200mm-wide steel cord conveyor belts, moving 450 t/h of ore over 1500 meters—belt replacement frequency reduced from 8 months to 24 months, cutting maintenance costs by $300,000/year.
Underground Coal Mining: Coal transportation from working face to shaft. A Chinese coal mine adopted anti-static EP200 belts, eliminating 3 electrostatic discharge incidents annually and complying with national mine safety regulations. Belt width 800mm suits narrow underground tunnels.
Mineral Processing: Concentrate and tailings transportation. A gold processing plant used chevron-pattern belts for 35° inclined conveyors, preventing concentrate slippage and increasing transportation efficiency by 20%. The belt’s oil-resistant cover withstands hydrocarbon leakage from processing equipment.
Q: What belt width fits 300 t/h coal transportation?
A: 1000mm width with EP300 reinforcement is standard for 300 t/h capacity. For higher inclines (＞25°), choose chevron pattern to avoid slippage—this reduces material loss by < 1%. Narrower 800mm belts can be used if space is limited, but throughput drops by ~15%.
Q: How to repair minor belt damage?
A: Use cold vulcanization patches for cuts < 50mm. Clean the damaged area with acetone, apply adhesive (bond strength ≥ 3 MPa), and press the patch for 30 minutes—this restores 90% of original strength. For cuts > 50mm, hot vulcanization repair is required to avoid further tearing.
Q: Can it handle wet and muddy materials?
A: Yes, the anti-skid pattern and drainage holes (optional) prevent material buildup. Drainage holes (φ5mm, spacing 100mm) reduce water retention by 80% in wet clay transportation. The rubber cover’s water absorption rate is < 1% after 24-hour immersion.
Q: What’s the maximum conveyor length supported?
A: Steel cord reinforcement supports up to 2000 meters in a single section. For longer distances (2000-5000 meters), connect multiple belts with mechanical fasteners (tensile strength ≥ 4000 N/mm) or hot vulcanized joints—joint efficiency reaches 95% of belt strength.
