北京矿冶研究总院和首钢矿山公司水厂铁矿从1980年4月开始进行圆锥水力分级机的研究。通过小型、半工业型试验,于1982年10月至1983年11月相继完成工业试验和工业试生产考核,所得结果证明,φ3000圆锥水力分级机设备运转正常,溢流浓度自控灵敏,指标提高幅度稳定,技术经济效益显著。
Beijing Mining and Metallurgy Research Institute and Shougang Mining Company Iron Works iron ore from April 1980 began cone hydraulic classifier. Through small and semi-industrial tests, from October 1982 to November 1983, the industrial tests and industrial pilot production tests were successively completed. The results showed that the φ3000 conical hydraulic classifier was operating normally and the overflow concentration was highly self-controlled and the index was increased Stable, significant technical and economic benefits.
