系统动力学（SD）是一种数学建模方法，用于理解和分析复杂问题。在这项研究中，假设碰撞作为主要的能量传递事件，SD模型是第一次开发量化的行星式米尔斯磨的研磨能量。这种建模方法的主要优点是考虑了各种铣削参数的依赖性。由来自Majini-Iassona方程的SD模型估计的研磨能量允许预测作为时间的函数的平均粒度和研磨温度。一个很好的协议被发现之间的模型和一些实验研究的结果，建议该模型的优点。
System Dynamics (SD) is a mathematical method of modeling to understand and analyze complex problems. In this study, assuming collision as the dominant energy transfer event, a SD model was for the first time developed to quantify milling energy in planetary ball mills. The main advantage of this modeling approach is that the dependency of various milling parameters is considered. The milling energy estimated by the SD model, which is derived from Majini–Iassona equations, allows predicting the mean particle size and milling temperature as a function of time. A good agreement was found between the results of the model and some experimental studies, suggesting the merit of the proposed model.
