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 performance.

This paper presents a numerical study of particle flow and sieving behavior on a vibrating screen. The particle flow is modeled by means of discrete element method (DEM) at a particle scale. The DEM model is first verified by the good agreement between the numerical and experimental results in terms of the distribution of percentage passing of different sized particles along the screen deck ...

They are a fine screen and are able to process particles sized down to 500um due to their shape. The screen is fed from the top with slurry where the slope is practically vertical, while the deck changes in an elliptical fashion such the discharge is almost horizontal.

This paper presents how different materials used in screen decks affect the screening process. The strength and elasticity has been examined in order to study how the aperture will change with different materials and also how different shapes of the aperture and the material of screen media affect the screening performance by analyzing different material flow.
