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.
The particle morphology and particle size distribution characteristics of the ground iron ore tailings from Qida Mountain were studied by scanning electron microscope (SEM), field emission scanning electron microscope (FE-SEM) and laser particle size analyzer (LPS). The specific surface area Iron tailings and water quenching blast furnace slag.The results show that the iron tailings are much better than the water quenching blast furnace slag; iron tailings by experimental ball mill grinding 140min, able to fill the accumulation of cement powder Particle size of the structure gap of less than 5μm particle size of 62.60%, and also contains a large number of sub-micron and nano-particles.
