克利夫兰克利夫斯铁矿公司的生产工艺过程,包括矿山规划、采矿、物料运输、破碎、磨矿、选矿、球团等,其过程自动化显著提高了生产效率,而其基本投资费用低于主要工艺流程的改造费用。讨论了基于经济效益优先,利用适于矿山应用的公用系统,实现矿山工艺过程自动化的策略及其结果。还介绍了希宾铁燧岩公司和帝国铁矿所实施的工艺过程控制的技改项目。
Cleveland Cliffers iron ore production process, including mine planning, mining, material transportation, crushing, grinding, mineral processing, pellets, the process automation significantly improves production efficiency, and its basic investment costs lower than the main process The cost of the process of transformation. This paper discusses the strategies and results of automating the mining process based on the priority of economic benefits and the utilization of common systems suitable for mining applications. Also introduced the technical renovation project of the process control implemented by the Hibbing Taconite Company and the Imperial Iron Ore.
