Analysis of Discharge Uniformity of Vibrating Screen Based on EDEM Discrete Element Simulation
A kind of slag adding device with bidirectional vibrating screen was designed.In order to evaluate the effect of vibra-tion assisted screen adding slag,a visual and quantitative analysis method of discharging uniformity based on EDEM discrete el-ement simulation and MATLAB data processing was proposed.First of all,the DEM software is used to simulate the process of screen assisted slag addition.Secondly,through MATLAB data processing,realize the visualization of the cumulative distribu-tion of particles at the exit.Thirdly,the spatial uniformity calculation model is used to calculate the particle distribution unifor-mity of the outlet.Finally,the particle distribution in the inner and outlet of the screen and the uniformity of the particle distribu-tion at the outlet of the screen are compared under the two cases with and without two-way vibration.The results show that the two-way vibration makes the particles inside and out of the screen more dispersed,which effectively improves the discharge unifor-mity of the screen assisted slag feeding system.The method proposed in this paper can realize the visual analysis and quantitative analysis of particle distribution uniformity at the discharge outlet,and provide theoretical guidance for the optimization of screen structure and reasonable setting of screen vibration parameters in the process of auxiliary slag addition.
