In order to cope with the complex challenges brought about by the diversity of sintering raw materials，it is important to clarify how to achieve the best granulation effect by adjusting the granulation parameters under different raw material ratios. A series of granulation tests are used to study the effects of different granulation moisture，granulation time and alkalinity of the mixture on the granulation effect，and the granulation effect is comprehensively evaluated by key parameters such as negative pressure，flow rate，average particle size and air permeability index. The results show that the granulation effect of the batching scheme containing a higher proportion of adhesive powder and high alkalinity is significantly improved by extending the granulation time under constant granulation moisture. Under the same granulation time，the appropriate increase of granulation moisture can generally improve the granulation effect of sintering mixture， especially for the raw material ratio scheme with high hydrophilic mineral powder and the raw material ratio scheme with low alkalinity，and the improvement trend of the raw material ratio scheme with high alkalinity is the most obvious.
