Abstract：The numerical simulation researches about the process of vibrating screen had been done using the EDM (discrete element method).The relationship of loose and structural parameters based on the con-cept of density was analyzed.The influence of feeding rate on the laminate based on the concept of the fine particle ratio was analyzed.The result showed,the best parameters are:wire diameter is 0.75 mm,aperture is 0.7 mm,the inclination is 25°;the best feeding rate on best stratification is 4e+04 p/s.
