摘要：

For countermeasures of deterioration in iron ore, development of pretreatment technology for high quality iron ore fine is critical issue in the sintering process. However with increasing small particles, sinter productivity is decreased by lower permeability due to increment of un-granulated particles or considerably large granules. Therefore understanding of granulation phenomena becomes more important issue. Since moisture of iron ore largely relates to the granulation behavior, it is necessary to reveal the effect of moisture on granulation rate for controlling the process. In this study, granulation tests were performed and the size distribution of granule was analyzed with probability model and new model considering granulation rate. Based on the calculation results, the effect of moisture on granulation rate was discussed.
