降低大型半自磨机磨矿介质单耗试验研究与应用

Experimental Study and Application of Reducing Unit Consumption of Grinding Media for Large-scale Semi-autogenous Mill

针对袁家村铁矿矿石硬度高、半自磨机直径大的特点,通过优化磨矿介质材质以及加球方法,在保证磨机生产能力不变的前提下,降低介质单耗与磨矿电耗,达到缩减选矿生产成本的目的。

In view of the high hardness of Yuanjiacun iron ore and the large diameter of semi--autogenous mill, grinding medium unit consumption and power consumption are reduced without undermining the capacity of the semi--autogenous mill by optimizing grinding medium and feeding method, achieving the purpose of cost saving.
