Gravity Separation – Oliver Manufacturing
The gravity separation table, or air table, is commonly used to separate particles by weight and density. A separation table 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 particles from lighter particles.
