Gravity Separators Dry Separation Equipment Manufacturer

The Gravity Separator makes a highly sensitive dry separation on the basis of one of three particle characteristics: density, size or 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 ...

Gravity Separation – Oliver Manufacturing - How it works

How Gravity Separation Tables Work. 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.
