Research on Ore Crushing Process of Rotary Crusher Based on Discrete Element Method
The operation condition of the rotary crusher is complex,and there are many factors affecting the crushing per-formance of the crusher.In order to realize the dynamic visual observation and quantitative characterization of the ore crushing process in the rotary crusher,a simulation method of ore particle crushing based on discrete element method and discrete crush-ing model was proposed to carry out numerical simulation of the ore crushing process of a mine rotary crusher.By establishing a full-size physical model consistent with the structure of the industrial rotary crusher,calibrating the ore particle mechanical characteristics parameters based on physical tests,taking the productivity of the rotary crusher as the main evaluation index,comparing the simulation results with the field production conditions,the results showed that the two errors were very small,verifying the accuracy and reliability of the simulation model.It provides a new method for the study of operation optimization of rotary crusher.
