摘　　要：由于攀钢高炉渣中含有20%以上的TiO2,使其利用受到很大限制,为使高钛矿渣作为掺合材料应用于混凝土,需首先了解高钛矿渣的粉磨特性。本文中研究了粉磨时间与高钛矿渣细度之间的关系,对比了高钛矿渣与普通矿渣易磨性并分析了助磨剂对高钛矿渣粉磨的影响。结果表明,高钛矿渣的易磨性较普通矿渣差,可使用助磨剂提高高钛矿渣的粉磨效率。Due to TiO2 exceeding 20% contained in the blast furnace slag of PANGANG, its utilization is restricted. Before used in concrete as admixture, the grinding properties of high-titanium slag must be knowed at first. The relation of grinding time with fineness of high-titanium content slag is researched. The contrast on proterties of high-titanium content slag with general slag, and the effect of grinding aids on high-titanium content slag grinding are also studied. The results indicate that the grinding properties of high-titanium slag is worse than that of popular slag.It is proved that the grinding aids can enhance the grinding efficiency of high-titanium slag.
