Triple/S Dynamics' Gravity Separator utilizes highly sensitive dry separation to purify particles by three characteristics: density, size, and shape. When size and shape are controlled within certain limits, the gravity separator is unmatched in its ability to separate a complex mixture by density. The relative size and shape of each component of the mixture also bear on the efficiency of the separation. Wide variations in these material characteristics can dramatically affect the separation results.

Triple/S Dynamics Gravity Separators are equipped with a porous deck, which is inclined and subjected to vibration, which causes material in contact with the deck surface to convey up the inclined surface of the deck. Low-pressure air is forced through the deck to fluidize the dry mixture so that the lighter materials are lifted from the deck surface and allowed to float down the inclination of the deck. The final result, presented at the discharge face of the deck, is a continuous, graduated progression from the least to most dense, smallest to largest, and least to most aerodynamic.
