At present, the economic benefits of double inlet and double outlet ball mills, which are commonly used in coal-fired powerplants, need to be improved. Based on this, this paper explores the factors influencing the output of double inlet and doubleoutlet ball mill by establishing the output system of double inlet and double outlet ball mill. By analyzing the influencefactors of the output of double inlet and double outlet ball mill, and combining with system dynamics, the dynamic modelof double inlet and double outlet ball mill output system is established, and SPSS is used to fit the model data with the realdata. The fitting degree is above 0.8, and the authenticity is high. The simulation results show that the impact energy ofbarrel grinding, the grinding powder fineness, and the pressure ratio in the ball mill affect the output of double inlet anddouble outlet ball mill according to certain relations. Finally, the research in this paper provides theoretical and technicalsupport for improving the economic benefits of double inlet and double outlet ball mills.
