Kinematics Investigations of Bulk Material Motion in Screw Sieve. Part I

There are offered working devices of the equipment for bulk material separation (working environment) ensuring bulk material motion with high amplitude. The developed classification of screw sieves is presented, the peculiarities of conditionally cylindrical shaped screw sieves and their models are shown. The design peculiarities and technologies for the assemblage of some sieves are investigated. The investigation results of bulk motion parameters depending on design peculiarities of a screw sieve are presented.
