利国铁矿破碎系统的适应性改造

Adapative Transformation of the Crushing System in Liguo Iron Mine

利国铁矿为了适应矿石性质的变化 ,对破碎系统进行了适应性改造。简化工艺流程 ,更新干式磁选设备 ,合理调整工艺参数 ,从而达到了降低入磨粒度、提高废石抛出率、减轻工人劳动强度等目的 。

In order to suit the change of ore properties,Liguo Iron Mine has made an adaptive transformation of its crushing system,which includes the simpilification of the technological flowsheet,the renewal of dry magnetic separators and the rational adjustment of the technological parameters so as to reduce the grinding feed size,to raise the waste discarding rate and to reduce the labour strength.As a result,remarkable benefit has been achieved.
