In vibrating screens, no distinct flow regime can be delineated because all flow regimes noticeable in the system occur concurrently. When the flow is dilute and highly sheared, the particles interact via collision and a constitutive law similar to the kinetic theory for dense gases can be deduced.

"A vibrating motor imparts both linear and vertical motion to a deck or screen surface, causing particles to move across the screen. As these particles encounter the openings in the screen mesh, smaller particles pass through, while larger ones are retained." The applications of vibrating screens are diverse, spanning various industries.

PURPOSE OF VIBRATING SCREENS. Screens are used mainly for the following purposes: Scalping. By scalping it is meant screening of coarse material in order to remove the undersize, typically before a primary crusher. Because of the coarse feed the top deck, which may be the only one, is often of a grizzly type. i.e. grizzly bars as …
