摘要：
The main structure and characteristic parameters affecting the working performance of vertical screw stirring mill were analyzed and studied，and the selection method of key working parameters was proposed. Based on the discrete element method，the simulation model of vertical screw stirring mill was established，and the effects of spindle speed，agitator lead and grinding medium size distribution on grinding performance were analyzed. The comprehensive grinding performance index was put forward，orthogonal tests were carried out for each parameter，and the quantitative value of grinding effect was obtained，and then the optimal working parameter combination under specific weight coefficient was obtained，which provided a reference method for the optimal design of the mill. © 2024 Editorial Board of Jilin University.
