  DEM simulation of particle flow and separation in a vibrating …

  202321 · Meanwhile, in the experiment, the screening efficiency was 66.96%, and the total misplaced material was 18.48%. The near-aperture particles needed a longer screening time (screening length) to pass through the screen. Future work. The effect of particle shape has a great influence on the movement and penetration of the material.

  DEM study of particles flow on an industrial-scale roller screen

  2020111 · Fig. 1 shows the configuration of the industrial-scale roller screen. Table 1 gives the geometrical and operational parameters used in the simulations. The roller screen mainly consists of a frame supporting the whole device, rollers with shaped discs screening particulate materials, motors providing rotation force, sidewalls holding the rollers, dust …

  Stepwise shape optimization of the surface of a vibrating screen

  2021101 · Introduction. Screening is an indispensable technique in which materials are separated according to differences in material properties. A vibrating screen is an effective screening device that sorts granular material according to particle size, and it has been extensively adopted in many modern industrial fields, including agriculture (Li, Gao, …

  Discrete particle simulation of particle flow and separation …

  In addition, the sieving behaviour of individual particles is analysed based on the microdynamics information, particularly the particle-screen interactions. On this basis, the probability of a single attempt and the number of attempts for a particle to pass an aperture are modelled for different shaped apertures, which are linked to the macroscopic sieving …

  Vibration screening: A detailed study using image

  202081 · Due to its versatility, screening is a widespread operation in the industry and can be used in solid–solid and solid–liquid separations, according to the screen aperture used and the particle size of the solids (Guerreiro et al., 2016, American Societyof Mechanical Engineers– ASME, 2005).

  2023825 · The smaller the particle size to the aperture, the higher the probability of passing the screen, while the nearer the particle size, the lower the probability of passing the screen. Near-sized particles also tend to plug the apertures thereby reducing the available open area. Particle Shape Spherical particles pass with equal probability in any ...

  Discrete particle simulation of particle flow and separation …

  201761 · Abstract This paper presents a numerical study on the effect of aperture shape on particle flow and separation in a vibrating screen process. A three-dimensional discrete element method (DEM) model is developed to simulate vibrating screens with rectangular apertures of different aspect ratios and orientations.
