Discrete particle simulation of particle flow and .

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 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.
