用深锥浓缩机处理浮选尾煤是煤炭部实现选煤厂煤泥水闭路循环的会战项目之一。在徐州矿务局夹河煤矿领导下,在平顶山选煤设计研究所、西安煤矿设计院、开滦煤炭科学研究所和四川矿业学阶等单位的参加下,组成了工人、干部和技术人员三结合试验组。自1974年以来,试验组以夹河矿洗煤厂为试点,依靠工人阶级,大搞群众运动,通过边试验、边研究、边 Using deep cone concentrator to treat flotation tailings is one of the battles that coal ministry has realized closed loop of slime water in coal preparation plant. Under the leadership of Jiahe Coal Mine in Xuzhou Mining Bureau, with the participation of Pingdingshan Coal Preparation Design Institute, Xi’an Coal Mine Design Institute, Kailuan Institute of Coal Science and Sichuan Mining Academy, three groups of workers, cadres and technicians Combined with experimental group. Since 1974, the experimental group took the pilot project of Jiahe Coal Preparation Plant, relying on the working class, mass mobilizing the masses, passing side-by-side testing, side-study
