我厂继鞍钢大孤山铁矿,首钢大石河铁矿及马兰庄铁矿、玉泉岭铁矿等单位应用细筛之后,于1979年5月全厂实现了细筛化。在金属回收率没有降低的条件下,铁精矿品位和球磨机能力都得到不同程度的提高,尤其是铁精矿品位提高的幅度较大,1978年为66.41％,而使用细筛后的1979年达到68.08％,提高了1.67％,其它各项指标也都完成和超额完成了国家计划。
I plant following the Ansteel Dagushan Iron Mine, Shougang Dashihe iron ore and Malanzhuang iron ore, iron ore and other units Yuquan Ling fine sieve, the whole plant in May 1979 to achieve the fine sieve. In the metal recovery rate did not reduce the conditions, the grade of iron concentrate and ball mill capacity have been improved to varying degrees, especially iron concentrate grade increased significantly, in 1978 was 66.41%, and the use of fine sieve after 1979 Reaching 68.08%, an increase of 1.67%. All other indicators have also completed and surpassed the national plan.
