Abstract 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.
