Based on the macroscopic angle of mass and energy conservation, this paper analyzes the characteristics of ball mill coal pulverizing system deeply. By using the principle of system dynamics and taking causal loop diagram and stock and flow diagrams as its carriers, it proposes a modeling scheme of ball mill coal pulverizing system. In addition, through comparing and analyzing simulation curves of the new and traditional models, and the accuracy of system dynamics model can be verified. The system dynamics model's structure is with distinct hierarchy and suitable complexity, which is well closed to the actual system. Meanwhile, system dynamics provides a new idea and a method of modeling and optimization in the whole coal-fired power plant.
