Abstract：In granulating experiments, the influence of moisture content, material size and distribution on granule size and distribution are investigated and analyzed as well. The results indicate: (1) with increasing the moisture content the granule size increases in the range of the suitable moisture, on the contrary the granule size decreases when the moisture content is too high. (2) the influence of the material size on the granule size plays a dominant role, and compared with which, the moisture content creates a minor effects on granule size; (3) the predicted value obtained from our mathematical model of the granule size and distribution is in satisfactory agreement with the experimental data, which has supplied the theoretical basis for applying the mathematical model to the practical sintering process. When the material size distribution is the Gauss distribution the granule size distribution is Gauss distribution too. But also the mass density function of the granule size distribution can be ascertained by the mass density function of the size distribution and the particle partition coefficient for the material.
