铁矿石粉磨设备研究分析

Research on the milling equipment for iron ore

从目前国内铁矿基本情况和预磨技术在铁矿山应用中的碎磨要求出发,对常用的新型颚式破碎机、新型圆锥破碎机、高压辊压机和新型立式辊磨等预磨设备进行了综合比较,对主要预磨设备的介质磨耗也进行了对比分析。而后,重点介绍了广义立式磨作为一种新型节能技术设备在矿山预粉磨中的应用,并指出它是目前技术水平和工艺条件下较为理想的预磨设备。

Aimed at the current basic situation of the domestic iron ore and the requirement of the pre-milling technology applied to iron mines, the article carries out the comprehensive comparison of the ordinary new pre-milling equipments： a new jaw crusher, a new cone crusher, a high-pressure roller squeezer, a new vertical roller mill. Also it compares the media abrasions for the major pre-grinding equipments. And then it emphasizes the application of vertical mill as a new energysaving equipment to the mine pre-milling artd proposes that it is the more ideal pre-milling equipment under the current technologies.
