A method and device are used for separating particles of plastic foil from organic material. The device includes a chamber with a perforated wall. A mixture of particles of plastic foil and organic material is fed into the chamber through a feed opening. The mixture is set into a rotating movement inside the chamber by a rotor. In the vicinity of the perforations, the centrifugal force to which a particle is subjected is at least fifty times greater than the gravitational force to which the particle is subjected. An airflow is generated in the chamber parallel to the rotational axis of the rotor. Particles of organic material leave the chamber through the perforations. Particles of plastic foil are carried along by the first airflow and then discharge through an opening in the chamber.

The invention relates to a device for continuously sorting a particulate stream, comprising: a) a conveyor (1) for conveying the particulate stream to a separation device, b) a sieve (7) for separating the particulate stream according to size, characterized in that it further comprises c) a per-sieve (3) comprising elongated sieve openings located between the convey or outlet and the sieve d) and a mechanical impact device for providing mechanical impacts to the pre-sieve (3). The pre-sieve allows to separate elongated objects like threads or wires form the particulate stream which would otherwise clog or block subsequent separation devices including the sieve.

An apparatus, system, and method are disclosed for a polishing chamber assembly. An apparatus includes an inner drum positioned on a first axis and forming an inner chamber interior to the inner drum. The inner drum includes a plurality of inner drum perforations formed in the inner drum, an object intake disposed tangential to the inner drum at a proximal end of the inner drum, and an object outlet disposed at a distal end of the inner drum. The apparatus includes an outer drum disposed around the inner drum and forming an annular chamber interior to the outer drum and exterior to the inner drum. A cyclonic gas flow is generated within the apparatus from the object intake to a gas outlet in response to drawing gas from the apparatus through the gas outlet to remove debris from objects within the inner drum.
