为了拓展铁矿资源，新兴铸管公司计划在印度建设一条200万吨的球团生产线，利用印度赤铁矿生产氧化球团。通过模拟链箅机－回转窑生产工艺，对印度赤铁矿造球性能进行了实验研究，得出：经细磨后的印度赤铁矿小于200网目的矿粉应达到65%以上，配加膨润土的比例为1％左右；在微型球团矿焙烧模拟系统中，采用正交实验的方法，确定了干燥段和预热段的工艺参数，为在印度建设球团生产线的工艺设计提供了实验依据。

In order to exploit iron ore resources, Xinxing Pipes Co. plans to build a two- million-ton pellet production line in India, using Indian hematite to pelletize. The experiment on the property performance of pelletizing with India hematite were carried out by simulating the grate-kiln pellet process in laboratory. The results show that the fine ore whose size less than 200 mesh should be over 65 in mass percent, after grinding, with the ratio of bentonite about 1%. Also, the process parameters of drying and preheating sections were determined by the orthogonal experiment in the micro-pellet roasting simulation system, which provide a reference for the design of the pellet production line in India.
