Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all...

Air Tabling—A Dry Gravity Solid–Solid Separation Technique ...

Abstract. The air table is a compact gravity-separating device, which does not require the separation of the low-density fraction from the air stream. Being a dry process, air tabling has a clear advantage over wet separation techniques because it does not require chemical pretreatment of the sample, treatment of water from...

Gravity Separation – Oliver Manufacturing

How Gravity Tables Work. A gravity separator, or air table, is commonly used to separate particles by weight and density. A separation can be used for any dry material as it moves on a “fluidized” bed of air across the table. The separator creates eccentric motion and has an adjustable uphill tilt which separates heavier...
