SWECO Vibratory Sieve Shaker or Vibratory Shaker
Basically, the SWECO Separator is a Vibratory Sieve Shaker that vibrates about its center of mass. Vibration is accomplished by eccentric weights on the upper and lower ends of the motion-generator shaft. Rotation of the top weight creates vibration in the horizontal plane, which causes material to move across the screen cloth to the periphery.
Piping Vibration - an overview | ScienceDirect Topics
For evaluation of piping vibration caused by gas–liquid two-phase flow, specifying or estimating flow patterns is of primary importance because the characteristics of the excitation force depend on the two-phase flow patterns. Many maps to estimate flow patterns from flow conditions, flow rate, and physical properties exist. For example, one of the maps is the Weisman map shown …

Vibratory Sifter Screen Separator - Vibrating Round Separator
A Vibratory Sifter is a Screen Separator is a screening machine that vibrates around its centre of gravity. Vibrating of screens is done by eccentric masses on the lower and upper ends of the motion-generating piece. Rotating the top mass in a circular motion, creates a horizontal plane vibration, causing material to travel across the stainless steel sieve and over to the periphery …
