In this study,a physical and mathematical model was established to simulate the dry centrifugal granulation (DCG) process of blast furnace slag,and the process was verified by small scale experiments.The influences of various factors,including molten slag temperature(or viscosity),surface tension and rotary speed of the flat plate-type disc,on DCG process were analyzed and optimum parameters were obtained.The results show that the granulation can be greatly improved by increasing the rotary speed.In addition,by boosting the temperature(or reducing the viscosity) or decreasing surface tension of the molten slag,the granulation effects can also be promoted.
