北京矿冶研究总院研制的LCH-X5米。充气机械搅拌式浮选机,在山东金岭铁矿完成了工业试验。中国有色金属工业总公司委托山东省冶金工业总公司主持并指定北京有色冶金设计研究总院为技术负责单位,对该浮选机进行技术鉴定。鉴定会于1984年10月25—26日在山东金岭铁矿进行,有14个单位的29名代表出席会议。该浮选机具有结构独特的双面叶轮和盖板,能造成双向循环矿浆和双向充气,单位面积充气量最大可达2.08米~3/米~2·分,充气量可按工艺要求进行调节;叶轮周速低(5.5～6米/秒),叶轮与定子的间隙大,磨损较轻,更换周期比6A浮选机延长2倍以上。用该机配置成一粗二精(精选用6A浮选机)的工艺流程,处理金岭含铜钴的磁铁矿,与工艺流程相同
Beijing Institute of Mining and Metallurgy developed LCH-X5 meters. Inflatable mechanical mixing flotation machine, completed an industrial test in Shandong Jinling iron ore. China Nonferrous Metals Industry Corporation commissioned Shandong Metallurgical Industry Corporation presided over and designated Beijing Nonferrous Metallurgical Design and Research Institute as the responsible unit of technology, the flotation machine technical appraisal. The appraisal was conducted at the Jinling Iron Mine, Shandong Province, from October 25 to October 26, 1984, and 29 representatives from 14 units attended the conference. The flotation machine has a unique structure of the double-sided impeller and cover, can cause two-way circulation of pulp and two-way inflatable, the maximum inflatable area per unit area of up to 2.08 m ~ 3 / m ~ 2 · min, inflation can be adjusted according to process requirements ; Low speed of the impeller (5.5 ~ 6 m / s), large gap between the impeller and the stator, less wear and tear, replacement cycle longer than 2 times the 6A flotation machine. The machine is configured into a rough two fine (Featured with 6A flotation machine) process, dealing with Jinling cobalt-containing magnetite, with the same process
