由昆明冶金研究所设计,昆钢和昆明冶金修配厂等九个单位协同制造的φ1560m/m平环式强磁选机,从1978年7月15日至1979年1月9日已带矿运转2266小时,处理矿量三万四千多吨,产出精矿一万四千多吨。为了评价该机的性能,省经委和省冶金局于2月24日至28日在昆钢上厂矿召开了技术讨论会。参加会议的省外有七个单位,省内十六个单位,共有代表90名。
The φ1560m / m flat-ring type strong magnetic separator designed by Kunming Institute of Metallurgy, Kunming Iron and Kunming Metallurgical Reconditioning Plant and other nine units co-produced with ore from July 15, 1978 to January 9, 1979 2266 hours, handling more than 34,000 tons of ore, producing more than 14,000 tons of concentrate. In order to evaluate the performance of the aircraft, the Provincial Economic Commission and the provincial Metallurgical Bureau held a technical seminar on February 24-28 at the Kunming Iron and Steel Plant. There are seven units outside the province attending the meeting, sixteen units in the province, and a total of 90 delegates.
