As a leading China manufacturer of cast polyurethane products, we specialize in supplying high-quality custom cast ball mill liners . Our liners feature superior wear resistance, impact tolerance, and low noise, outperforming traditional metal alternatives while meeting environmental standards .
Polyurethane ball mill linings are used extensively in mining, cement, mineral processing, quarrying, and aggregate grinding. Typical applications include SAG and ball mills for ore grinding, cement ball mills, regrind mills, and pebble mills. We support customers in marine mineral projects, bulk handling yards, automated grinding circuits, and remote mine sites with sample liners, installation training, and agent‑managed logistics.

Case Studies: How Polyurethane Ball Mill Linings Solved Client Challenges?
Case 1: Mining Client in Australia
A iron ore mine was struggling with frequent metal liner replacements (every 6 months) and high noise . We provided custom cast polyurethane liners with Shore A 85 hardness. Result: Service life extended to 18 months, maintenance costs reduced by 35%, and on-site noise lowered by 20dB .
Case 2: Cement Plant in Indonesia
The client needed to increase ball mill throughput while cutting energy costs . Our custom lift bar design liners optimized grinding efficiency. Result: Output increased by 44%, energy consumption dropped by 12%, and reline time halved .

Selection Guide of Polyurethane Ball Mill Linings
- Confirm your ball mill’s size, speed, and grinding medium (steel balls/alumina balls) .
- Match liner thickness to working intensity: 15-25mm for medium load, 30-50mm for high impact.
- Choose hardness based on material: Shore A 80 for soft ores, 85 for hard rock/cement clinker .
- Select material grade: Corrosion-resistant PU for wet grinding, high-temperature PU for ≥60℃ environments .
- Discuss customization needs (design/installation) with our technical team for perfect fit .
- Request a free sample to test wear resistance and compatibility before bulk purchase.
