Applications of Discrete Element Method (DEM) in modeling the impact of dynamic and technological parameters on the material movement on the vibrating screen surface

A vibrating screen is a device for sorting materials, which is widely used in screening plants [1-3]. The availability of a vibrating screen relies on various parameters, such as dynamic parameters, technological parameters, and so forth [4-8]. When using the traditional method to calculate the design and determine the reasonable parameters for the machine to work efficiently, it would be rather challenging, and the accuracy is high. Also, this process would likely take a lot of time, as well as an increasing cost. This study aims to apply the Discrete Element Method (DEM) to simulate the influence of dynamic parameters and technological parameters on the operating capability of the machine. The results of the paper are graphs showing the importance of the oscillation frequency, the amplitude, the incline angle of the screening surface, the angle of oscillation on material velocity, and material elevation on the sieve. These are essential parameters that significantly affect the performance and productivity of the screen. The findings of the study may be useful for scientists to design parameters for vibrating screen reliability. � 2020 Published under licence by IOP Publishing Ltd.
