AIR TABLES
The core of air gravity table separators consists in an inclined vibrating screen deck on which material is fed evenly on the all width. The vibrating motion of the deck makes that material is forced to climb up the deck while at the same time material is also exposed to a constant and evenly distributed upward airflow. Separation takes place between light material that levitates under the action of the upward airflow and goes down the deck and, heavy material that does not levitate and rises up the deck.
