一、 為了提高磨鑛作业效率,必须使球磨机内的铁球保持一個最合理的状態,卽必须根据原鑛性质及要求的产品粒度適當地選擇球磨机的轉数和鐵球质量,同時必须合理控制磨鑛濃度及分析效率的配合。自1952年推行了蘇聯先進經驗,卽磨鑛鐵球合理裝入后,全國各浮選廠的磨鑛效率均有所提高,以球磨机毎小時处理能力來说,東北區如果1952年为100％,則1953年为121.5％,1954年为134％;全国如以1953年为100％,則1954年為112％,以曲線图表示,如第一图
First, in order to improve the efficiency of grinding operations, the iron ball in the ball mill must be kept in a most reasonable state. 卽 The number of rotations and iron ball of the ball mill must be properly selected according to the nature of the ore and the required product size. At the same time, it must be rationally controlled Grinding ore concentration and analysis of efficiency. Since 1952 the Soviet advanced experience was introduced, 合 grinding iron ball properly loaded, the national flotation plant grinding efficiency have increased to ball mill 毎 hour handling capacity, the Northeast if 1952 was 100% , Then 121.5% in 1953 and 134% in 1954. If the national average was 100% in 1953, the figure was 112% in 1954, as shown in the graph
