Teeter Bed an overview ScienceDirect Topics

Teeter-bed separator is a vessel in which feed settles against an evenly distributed upward current of water. When the falling feed particles achieve the same velocity as the upward current, they will not fall any longer. The feed material builds into a bed within the cell, creating a teeter zone.
