金岭铁矿选矿厂磁选流程分析及改造

Analyzing of Magnetic Concentration Process Flow and Reformation of Concentrating Mill of Jinling Iron Mine

金岭铁矿选矿厂原磁选流程存在处理能力低、选矿指标波动大、过滤给矿浓度低等问题。为此 ,将 、 段磁选机大型化 ,并在 段磁选以磁选机代替磁聚机 ,从而扩大了生产能力 ,改善了选别指标 ,减少了水电消耗 ,降低了铁精粉水分。

The questions of low ore treating ability,big fluctuation of concentrating indexes,low filtering feed ore concentration,etc,are existed in old magnetic concentration process flow of concentrating mill of Jinling iron mine.For solving about questions the magnetic separators in first and second section are taken on large sized,magnetic aggregation machine is replaced by magnetic separator in third section,and thus the production capacity is expanded,concentrating ore indexes are improved,the consumptions of water and power are decreased and moisture in concentrated iron powder is decreased.
