Investigation of the effect of filling level on the wear and vibration of a SAG mill by DEM
文献摘要：
Semi-autogenous grinding (SAG) mill is widely used in the grinding process of coal and ores because of its strong applicability,large capacity and low consumption of grinding media.Therefore,the research of SAG mill is still of great important practical significance.Among those parameters of the SAG mill,the filling level is very important for it is not only directly related to the processing capacity of the mill,but also affects the operation cost and stability of mill.In this paper,combined with shear impact energy model (SIEM) and discrete element method (DEM),the particle collision energy spectrum was applied to analyze the influence of ore filling level and media filling level on the power draw of the mill,the impact energy on ore,and the wear of liner and media in a slice of an industrial SAG mill.It was found that increasing the ore filling level would increase energy consumption and reduce the energy efficiency and the wear of liner and grinding media.Furthermore,the vibration of mill was explored from the collision energy on liner.The results showed that the low frequency but high energy collision between grinding media and liner was the main reason for liner wear and mill vibration.
