摘　　要：针对100%印度赤铁矿生产氧化球团的可行性问题,对印度赤铁矿造球工艺参数进行了试验研究。在微型球团矿焙烧模拟系统中,通过模拟链箅机—回转窑生产工艺,采用正交试验的方法,得出:经细磨后的印度赤铁矿小于0.075 mm的矿粉应达到65%以上;配加膨润土的比例为1%左右;按照试验得出的干燥段和预热段工艺参数,实现100%印度赤铁矿造球是完全可行的。The experiment on the feasibility of pelletizing with 100% Indian hematite were carried out to research the palletizing processing parameters of using Indian hematite. Based on the orthogonal experiment method, some simulating research of the grate-kiln pellet process were done in the micro-pellet roasting simulation system in laboratory scale,. The results show that the fine ore whose size less than 0. 075 mm should be over 65 in mass percent, after grinding, with the ratio of bentonite about 1%. According to the process parameters of drying and preheating sections which got from experiment, it will be successful that using 100% Indian hematite to pelletize.
