Customized Meihuan Polyurethane Rubber Sheets

List some characteristics of polyurethane for mining applications.

Excellent corrosion resistance. Good wear resistance. Favorable friction properties. High elasticity. Lightweight, only one-sixth the weight of metal materials.

Polyurethane liners not only extend the service life of the liners but also reduce the overall machine weight (PU density is one-sixth that of metal), resulting in approximately 20% energy savings for the mill.

Additionally, polyurethane wear-resistant liners offer a certain degree of noise reduction, significantly improving the working environment. Practical experience shows that polyurethane wear-resistant liners last 2-4 times longer than metal liners and improve overall economic efficiency by more than double.

Research has found that using polyurethane or similar materials instead of rubber for liners is more effective in reducing wear on liner components. This material has a hardness between 60-90 Shore A and 80 Shore A, with sufficient elasticity; the hardness of this material is 85 Shore A.

Industrial trials and long-term practical applications by customers demonstrate that using polyurethane wear-resistant liners for many equipment components offers significant advantages, being both technically feasible and economically cost-effective.

For this reason, polyurethane wear-resistant liners are widely used in various major industries, such as vibrating screen meshes, high-pressure water pump impellers, belt rollers, centrifugal concentrator drums, flotation machine impeller covers, spiral classifier blades, mill liners, hydrocyclone liners, various sand nozzles, and various wear-prone troughs.
