A virtual experiment showing single particle motion on a linearly vibrating screen-deck
Vibration screening is a complicated process used in the mineral processing area that is affected by the vibration and other technical parameters of the screen and by the processed material's properties. The mo¬tion of the material on the screen deck has a direct relation to the quality of the screening process. Fac-tors such as the penetration probability of the parti¬cles and the productivity of the apparatus are important. So investigating the theory of motion and the properties of the screened materials is of great sig¬nificance for choosing reasonable kinematic parame¬ters that ensure an effective screening process.
The sieving experiment forms the foundation of screening theory. The traditional experimental meth¬ods have the disadvantages of being complex to oper¬ate, being easily influenced by outside conditions and being difficult to carry out accurately in small scale. Virtual experimental technology, on the other hand, has the advantages of low cost, of having no limits in the field related to the available time and number of tests and of affording the simulation of complex processes. Virtual techniques have been widely ap¬plied in studies within military, medical and industrial fields.
