【Abstract】 In the field of mining machinery, non metallic materials can only be used for the parts mostly failed due to corrosion-wear mechanism. The experimental results have shown that PU elastomers and MC nylon can be served as the ideal substitutions for the rotor of flotation machine. which has been proved out in practice更多还原
