  • METHOD FOR GRAVITY SEPARATION OF PLASTIC PARTICLES AND GRAVITY SEPARATOR FOR PLASTIC PARTICLES
    Publication number: 20140083916
    Abstract: 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.
