The further study on the mechanism of the influence of the speed rate and filling rate on the product size can provide a reference for the ultrafine vertical mill to propose a more reasonable grinding process, thus greatly improving the efficiency of the ultrafine vertical mill.
The research on the optimization of ultrafine vertical mill parameters mainly adopts numerical simulation and experiment. The grinding mechanism of ultrafine vertical mill is complex, and it is difficult to describe by analytical model. The discrete element method provides a means for the research of grinding mechanism of ultrafine vertical mill. Discrete element method is a suitable method
The numerical method of the mechanical behavior of discontinuous body is studied.
