Solids Processing Dry Separation Methods
Specific gravity separation While most engineers in industries that process dry materials know what a gravity separator (Figure 2) does, its work is difficult to define with precision. The statement "a separator classifies dry, free-flow-ing, granular mixtures by weight or bulk density or specific gravity" is accurate.Web

General Information. Gravity separators, or air tables, separate particles with very close specific gravities. The particles are fed onto a large, slotted deck that is tilted slightly, as shown here. The deck vibrates and fans force air upward. Denser particles travel to the high side of the deck, while lighter particles roll off the low side.Web
