Abstract:

A circular vibrating screen is a device for the separation of bulk materials into granules of different sizes, which is widely used in screening plants. The screening efficiency depends on various parameters, such as the vibration amplitude, vibration frequency, slope of screening surface, material properties, throwing index, etc. It is difficult to accurately assess the influence of these parameters on the screening efficiency by using conventional methods. In this work, the authors applied the Discrete Element Method (DEM) to simulate and analyze the effect of vibration parameters on the screening efficiency of circular vibrating screen. The results of the paper are graphs showing the importance of the vibration amplitude (A), the inclined angle of screening surface (αo), the throwing index (Kv), the material properties on screening efficiency of circular vibrating screen. The findings of the study may be useful for scientists to design parameters for circular vibrating screen reliability
