Rubber Screen vs MDI Polyurethane Screen for Mining Screening

Summary: Compare the performance of rubber and PU screens to help mines select cost-effective screening materials.

As mainstream screening materials, rubber and MDI polyurethane screens apply to totally different mining conditions:

1.Wear Resistance & Service LifeRubber screens suffer fast aging under high temperature and strong ore impact, service life around 2–4 months. MDI PU screens have compact molecular structure, wear resistance 3–5 times higher, stable operation for 6–12 months.

2.Anti-Clogging PerformanceRubber surface easily sticks fine mud. Elastic micro-vibration of MDI PU effectively avoids hole blocking, less manual cleaning required.

3.Working Condition AdaptabilityRubber suits low-abrasion, mild temperature scenes; MDI PU adapts high-abrasion ore, cold Siberian mines and acid-base slurry environment from -40℃ to 120℃.

4.Customization SupportWe cooperate with Qingdao University to upgrade rubber formulas; MDI PU supports full customization on hardness, aperture and size for all screening machines.

Industry Tip: For mines pursuing long-term low maintenance cost, MDI polyurethane screens are the priority choice.
