Fitting Method Research of Sieving Parameters of Vibration Screen and Sieving Efficiency Based on DEM

Abstract:

Nowadays, many scholars attach importance to how sieving parameters of vibration screen influence sieving efficiency. The traditional research of screening theory and technology depended on the screening test that consumed a lot of human labour, material resources and money.DEM software EDEM was used to establish the simulation model of screening in this paper. Five simulation particle shapes were built base on real shapes of stone particle. After completing 20 groups simulation, sieving efficiency were calculated based on ratio of undersize in feeding and undersize. The formula of sieving parameters and sieving efficiency was fitted with the method of multielement non-linear regression by Matlab based on simulation data. This paper provide a new method for vibrating screen designing and research of screening theory.
