细筛是六十年代末期才正式推广,投入生产使用的一种新型高效细粒筛分设备。由于它能有效地分离0.1~0.044毫米粒级,除去铁精矿中低品位高硅的粗颗粒,以达到提高精矿品位的目的,且具有经济可靠、操作维护简单、见效快、投资省等优点,所以无论是国外还是国内,在磁铁矿选厂、焙烧磁选厂、赤——磁铁矿选矿厂均得到广泛应用。本文试对细筛提高磁选铁精矿品位的流程进行分析,以供参
Fine sieve is the only officially promoted in the late sixties, put into production using a new type of high-efficiency fine-grained screening equipment. Because it can effectively separate the grain size of 0.1 ~ 0.044mm, it can remove coarse grains with low grade and high silicon content in iron concentrate so as to achieve the purpose of improving the grade of concentrate and has the advantages of economy and reliability, simple operation and maintenance, quick investment, and investment saving Advantages, so whether it is foreign or domestic, magnetite dressing plant, roasting magnetic separation plant, red - magnetite ore dressing plant are widely used. This paper attempts to improve the fineness of magnetic iron concentrate grade process for analysis
