| 摘 要： | 利用扫描电镜(SEM)、场发射扫描电镜(FE-SEM)和激光粒度仪(LPS)研究齐大山磨细铁尾矿的颗粒形貌和粒度分布特征,并以比表面积为评价指标,比较了铁尾矿与水淬高炉渣的易磨性.结果表明:铁尾矿的易磨性远远优于水淬高炉渣;铁尾矿经实验用球磨机粉磨140min后,能够填充水泥粉体堆积结构间隙的粒径小于5μm的颗粒质量分数为62.60%,并且还含有大量亚微米级和纳米级颗粒.

| Abstract: | The granule morphology and particle size distribution of milled iron tailings from Qidashan Iron Mine of China were investigated by scanning electron microscopy (SEM),field emission scanning electron microscope (FE-SEM) and laser particle sizer (LPS). The grindabilities of iron tailings and blast furnace slag were compared by taking specific surface area as an evaluating index of milling. The results show that the iron ore tailings have a much better grindability than blast furnace slag. The milled tailing ... |
