一、简介 分级溢流浓度的自动调节可使矿浆的浓度稳定,在矿石性质已定的条件下,可以使返砂量均匀,保持合适的磨矿细度,从而提高选矿指标,因此对矿浆浓度的测量与控制,是浮选厂急待解决的问题之一。矿党委决定要在自力更生的基础上想尽办法解决测量浓度的问题;我们组织了在选矿厂党支部直接领导的三结合小组,对差压法测浓度进行了周密的分析,统一了认识。经过反复的 I. INTRODUCTION The automatic adjustment of fractional overflow concentration can stabilize the concentration of pulp. Under the conditions of certain ore properties, the amount of sand returned can be made uniform and the appropriate grinding fineness can be maintained, thereby improving the dressing index. Therefore, Measurement and control of the flotation plant is one of the urgent issues to be solved. Mine party decided to self-reliance based on trying every means to solve the problem of measuring concentration; we organized in the dressing plant directly led by the party branch of the three combination of differential pressure method to measure the concentration of a careful analysis and unify understanding. After repeated
