Andrew Weir R & D
Science and technology R & D General Counsel material is well-known expert Mr. Chen Changshun, "a combination of self-retaining type (no bolts) ball mill liner" is Mr. Chen Changshun's "mill systems engineering theory" as the guide of the invention for the past century Mill Liner epoch-making product. Its stability, reliability, significantly more than traditional liner, the metal material to obtain the most effective use, greatly reduce labor intensity and improve the working environment. "Chen liner" has reached the world advanced level, Mr. Chen Changshun many domestic and foreign materials experts to establish a "wear-resistant materials research base" Anli Tai Group, to build the international representation of the product.
The company was established in academician workstation, and invest 5 million to establish a national-class wear-resistant materials research and development center. New Project high-chromium alloy roll ring, six times the normal service life of the roller ring, and the cost is only 2 times the ordinary roller ring, not only replace imports, but also exported to Australia, Russia, India and Southeast Asia. Put into this project is not only a key step to achieve Aetna Group operations and for listing, but will greatly enhance the life of the mine with submersible pumps with patented new high chromium wear-resistant materials.
