Gravity Table

Gravity separators are a type of dry separation equipment. They can process a complex mixture of dry materials and separate the different individual particles depending on their density, resulting in a continuous gradation across a range of different densities. Gravity separators are also commonly referred to as fluidized-bed separators, air tables, and density separators.

Oliver Manufacturing’s gravity separators divide heavier particles of material from lighter particles differing in their specific densities. On gravity separators, lighter particles are moved upward through the fluidized bed, and heavier particles sink downward. This air essentially makes the particles weigh themselves. The deck itself is tilted uphill and quickly shifting in a perpendicular eccentric motion. This allows the lighter particles to flow over the top of the heavier particles to the bottom of the deck while heavier particles are driven up and over the top. This process allows our gravity separators to separate both light and heavy contaminants from a product simultaneously.
