## 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.

## THEORY AND OPERATION OF THE SPECIFIC GRAVITY

The two main parts of the gravity separation process are air and table motion. If we understand how these two things work together then we have the basis for good operation. The basic principle of operation of the gravity separator is that it takes ad-vantage of the difference in size, shape and specific gravity of particles.

## Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the material being suspende
