Abstract£ºIt is difficult to observe the migration characteristics and qualitative analysis of the screening effect of the uranium doxide sintered block, off lid, broken material and other slag block mixture after it is poured into the vibrating screening equipment from the sintered molybdenum boat. The discrete element method(DEM) was used to establish a numerical model of uranium dioxide block mixture screening, and the vibration efficiency of uranium dioxide sintered product under the existing structure and vibration characteristics was quantitatively analyzed and studied. Through the data processing of the simulation results, the vibration stratification coefficient, screening efficiency and other quantitative parameter were obtained. For all the characteristics of the stratification effect of the sintered products of uranium dioxide in the vibrating screening equipment are obtained, and the characteristics of the stratification effect are analyzed and summarized.
