摘要
针对选矿厂长期存在的铁精矿粒度粗的问题, 从一段磨矿的局限性和磨前预选工艺的负面影响简单地分析原因, 通过对分级溢流和铁精矿进行筛析研究, 提出了应用高频细筛分别控制分级溢流或铁精矿粒度的两套改造方案。
It is a long time problem that iron ore concentrate in dressing plant is coarse.Generally,it is imputable to limitation of one-stage grinding and negative influence of pre-dressing prior to ore grinding.According to screen analysis of overflow from classification and screen analysis of concentrate,two methods can be selected to increase fineness of concentrate:control of classification overflow or control of size of concentrate by means of high-frequency fine screen.
