某选矿厂在全体职工的积极努力下,做了許多改进,例如縮小碎矿最終产品粒度、实行合理裝球(增加小球比例)推行粗磨、提高溢流濃度等,不仅使磨矿处理量不断提高,并且选矿回收率亦有所上昇。到1957年4月份,該厂磨矿的月处理量已較原设計增加了1.52倍。在总路綫的光輝照耀下,全厂职工发揮了冲天的革命干勁和共产主义风格,采取了一系列的改进措施使磨矿处理量又较1957年4月份时增加了69%,最高时曾达到原設計的449%。获得这些成績的重要經驗是:
With the active efforts of all the staff and workers, a number of improvements have been made. For example, reducing the size of the final product of crushing ore, implementing rational ball loading (increasing the proportion of pellets), carrying out coarse grinding and increasing the overflow concentration not only make the grinding capacity Continue to improve, and beneficiation recovery rate also increased. By April 1957, the mill’s monthly processing capacity had increased by 1.52 times compared with the original design. Under the brilliant shine of the general route, all the workers of the entire factory exerted a radiant revolutionary drive and communism style and adopted a series of improvement measures to increase their grinding capacity by 69% over April 1957. At the highest time Had reached 449% of the original design. The important lesson to be gained in these achievements is:
