INDUSTRIES SERVED: Mining, Cement, Metallurgy
As a dedicated China manufacturer and supplier of mining consumables, we specialize in high-performance flotation wear polyurethane components. Utilizing advanced hot-casting technology and premium prepolymers, we engineer rotors, stators, and diffusers that withstand the harsh conditions of mineral processing. Unlike traditional rubber, our custom cast polyurethane offers a tighter molecular structure, providing exceptional resistance to sliding abrasion and impact. We control the entire production process, ensuring consistent quality and dimensional accuracy for every batch we ship gloablly.
Our wet and dry end wear components include rotors, impellers, diffusers, hoods, dispersers, stators, guards, base plates, bearing stands, draft tubes and standpipes. These components are critical in the mining and beneficiation industries. They are primarily used in flotation cells ,pipe and cyclone lining for separating valuable minerals like copper, gold, molybdenum, and lithium from ore. Our polyurethane parts are also widely applied in coal preparation plants, potash fertilizer production, and aggregate washing facilities where keeping the slurry in suspension and generating fine bubbles is essential for recovery rates.

Case 1: Extending Life in Copper Mining
A copper mine was changing rubber stators every 4 months. We introduced our heavy-duty polyurethane stators. The wear life extended to 12 months, reducing shutdown costs. This success helped boost our supplier ranking within their procurement system.
Case 2: Energy Saving in Gold Processing
A client complained about high energy costs. We replaced steel impellers with our lightweight cast polyurethane rotors. The reduced weight lowered the motor amp draw by 15%, and our after-sales service team helped fine-tune the speed for better recovery.
‘
- Assess working environment: Choose corrosion-resistant options for saltwater/chemicals.
- Match hardness to wear level: 80A-95A for low wear; 60D-75D for high-abrasion mining. See how to choose right hardness.
- Confirm equipment specs: Provide CAD files for custom cast perfect fit with flotation cells.
- Calculate load/buoyancy needs: Select density (1.0-1.3 g/cm³) based on application.
- Prioritize reinforcement: Opt for steel-reinforced components for heavy-load scenarios.
- Test samples: Verify compatibility, wear resistance, and corrosion performance first.
Yes, as a manufacturer, we have a full engineering team. We can reverse engineer from a physical sample or build molds from your drawings.
Polyurethane generally offers better abrasion resistance, supports more intricate shapes (custom cast), and resists swelling from oils/reagents better than standard natural rubber.
The service life of polyurethane flotation parts varies by operating conditions (e.g., chemical exposure, ore abrasion), usage intensity, and maintenance practices. With their exceptional wear resistance, these parts usually last 2–5 years under normal use—far longer than rubber or metal alternatives—reducing downtime and replacement costs.
Polyurethane flotation parts are precision-engineered to optimize three key processes: uniform turbulence distribution, robust froth generation, and reliable particle suspension. They form a stable, controlled froth layer that traps valuable minerals effectively, slashing particle loss and maximizing separation efficiency for higher mineral recovery rates.
