A method and a device for gravity separation of plastics particles, in particular of plastic flakes, where separation gas is guided upwardly in the counter stream against the plastic particles to be separated. Due to the fact that the separation gas is at least partially ionized, the selectivity of the separation can be increased with low energy input.

Gravity Separation | Gravity Separator Machine for Sale ...

2 The working principle of gravity separation. Most gravity separation processes involve two stages: loose-stratified and transport-separated. In the moving medium, the loose ore clusters form stratification of different density (or particle size) ore particles due to differences in the state of motion during settling.

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.
