Why Mines Choose Polyurethane?
Polyurethane solve three big mining problems: fast wear, frequent replacements, high costs. Over 100 mines worldwide have cut maintenance costs by 60%+. They fit crushing, conveying, screening equipment—ensuring easy installation, long-term stability and less downtime.
Advantages
Wear resistance: 2x that of manganese steel, 5x that of ordinary rubber
Withstands impacts, mineral slurry corrosion; works stably from -40℃ to 80℃
30% lighter, cuts equipment load and energy use by 15%
Custom-made for complicated parts (scraper conveyors, mine carts); easy to install
Key Application
Crushing Equipment
- Jaw crusher buffer pads, agitator,
- Impact plate liners (90A): Resist boulder hits; 2x longer life than manganese steel
- Cone crusher seals: Oil/dust-proof; 5x better sealing than rubber
- Hydrocyclone Linings: Vortex finders , spigots housing, cover plate liner, cone liner, vibrating screen spray nozzles, feed chamber liner, outlet and inlet Cone
Conveying Equipment
- Conveyor Scraper blade: (85A): Resist chain wear; Anti-static, flame-retardant
- Belt conveyor idler roller,
- Chute liners ,pipe lining, pipes and fittings
Screening Equipment
- Vibrating screen panels/plate: Self-cleaning, no clogging; 15% higher efficiency, 3-5x longer life than steel
- Classifier strips: Resist slurry erosion; last 12+ months in iron concentrate sorting
- Dehydration screen buffers, spiral classifier shoe, lining plate
Safety & Transportation Equipment
Underground anti-slip pads: Friction coefficient ≥0.7 in wet areas; fewer accidents
Mine cart wheels (90A): Shock-absorbing; polyurethane wheels for monorail transport systems
Success Cases
- UK Granite Quarry: 70mm-thick screen panels handled 2,200 tons/hour granite. 1.5 million tons screened in 12 months (50% over warranty); 80% less maintenance.
- China Mining Cooperation: Replaced old liners with polyurethane. Annual maintenance costs down 40%; liner life extended from 2 to 8 months.
