山东黄金昌邑铁矿200万t/a选矿厂破碎系统采用三段两闭路工艺流程,粗碎采用C110型颚式破碎机,中碎采用HP400型圆锥破碎机,细碎采用HPGR500/15-1000型高压辊磨机,最终破碎产品粒度在10mm以下。球磨机的能耗和钢耗较常规三段一闭路破碎工艺条件下的相应指标均降低50%,单位运行成本降低5.94元/t原矿,效果极其显著。
Shandong Gold Changyi iron ore mine 2 million t / a beneficiation plant using three sections of two closed-circuit crushing process, coarse crusher C110 jaw crusher, broken HP400 cone crusher, fine crusher HPGR500 / 15-1000 type High pressure roller mill, the final crushing product size below 10mm. Ball mill energy consumption and steel consumption than the conventional three sections of a closed-circuit crushing conditions were reduced by 50% of the corresponding indicators, unit operating costs to reduce 5.94 yuan / t ore, the effect is extremely significant.
