摘要
介绍了美国德瑞克公司的高频细筛在降低含硅量、提高铁精矿品位、控制粒度和磨矿分级中的应用 ,以及取得的技术和经济效果。同时比较了高频细筛和其他分级设备的特点 ,尤其是“重介效应”对分级的影响 ,建议用优质、高效的德瑞克高频细筛提高我国铁精矿质量 ,增强市场竞争力。
The application of American Derrick's high frequency fine screen in reducing silicon content,raising the grade of iron concentrate,controlling particle size and grinding-classification and the technical and economical effects achieved are presented.The characteristics of high frequency and other classification equipment,especially the 'effect of heavy medium' on the classification are analysed and compared.It is recommended that Derrick high frequency fine screen that is of high quality and efficiency be used to improve China's iron concentrate so as to raise its market competitive power.
