Method and system for evaluating granulation effect of sintering mixture granulation system

The invention relates to a method and a system for evaluating the granulation effect of a sintering mixture granulation system. The method comprises the following steps: respectively calculating the granulation effects of the granulation systems before and after transformation; comparing the granulation effect of the granulation system before modification with the granulation effect of the granulation system after modification to obtain a comparison result, and obtaining an evaluation result according to the comparison result. Wherein the granulation effect of the granulation system before modification is compared with the granulation effect of the granulation system after modification by adopting the content of the particle size of which the particle size is greater than 3mm or the average particle size in the mixture before and after modification, and if the variable quantity after modification and before modification is greater than 0, the modification is effective; if the variable quantity is smaller than
