摘　　要：以提高立式振动磨的粉碎效果与效率为目的,深入分析其工作机理及磨钵内磨介运动情况,得出了磨钵内磨介的受力方程;在此基础上,以粉体力学中单颗粒破碎试验和研究为依据,建立了磨钵内粉体颗粒的二维粉碎受力模型,得出了物料粉碎粒径与振动强度的关系式,为立式振动磨及磨钵的设计提供理论指导。In order to enhance the pulverization effect and efficiency of a vertical vibration pulverizer,the mechanical equations for milling medium are established by analyzing the working principle of machine and the movement situation of milling medium in the milling bowl.By establishing a 2-dimension mechanical model of powder particles in terms of single particle crushing test and research in powder mechanics,the relation expression for pulverization particle diameter and vibration intensity is established.The theoretical analysis provides guidance for the design of vertical vibration pulverization and milling bowl.
