The ensure using time of magnetic lining is 6-8 years, according to magnetic lining life 6-year period, in six years time, replace the access liner saves 8 days. (excluding the saving costs of replacement maintenance) increase the income of 328,300 yuan within six years х 8 days = 2,626,400 yuan. Representing that in one year income increase 437,700 yuan. New energy saving ball mill magnetic liner is thin, it is around 40% of high manganese steel liner, while the mill volume increases, the mill processing capacity can be increased by 3-5%, Mine ore production increased and improving economic efficiency. My company's fourth-generation Nano toughened metal composite magnetic liner had been used in early 2009 with success in MQG3660 ball mill, equipment operation four years and found no obvious signs of wear, no significant attenuation of the magnetic field. Our company take “Sincere man, realistic work” as the enterprise culture, “one mind and entrepreneurial innovation” as style, "take customer’s satisfaction as the standard" as the spirit of service, "Customer moved, excellent products, leading technology, everyone success" as Operation Philosophy, comprehensively promote the construction of enterprise, pursue and achieve the mission of "energy companies’ best partner".
