This application relates generally to a method and apparatus to deposit particles onto one or more coupons, and harvest particles from one or more coupons, which may beneficially provide a more uniform or localized distribution of particles over a specified area on each coupon. The application relates to a method and apparatus for depositing particles onto one or more coupons using a sieve. The application also relates to a method and apparatus for depositing particles onto one or more coupons using a dust storm. The particle loadings achieved on each coupon or across an individual coupon may be substantially uniform. The application further relates to a laser-based method and apparatus for transferring particles deposited at localized points on a source coupon to a different substrate for further use.

Separation and classification equipment for separating a mixed waste stream into first, second and third fractions. The equipment comprises a feeding member for feeding the waste stream toward a gap and a blower for discharging a stream of air for mixing with the waste stream, as the waste stream falls through the gap. The first fraction falls through the stream of air and collects in a first collection area while the stream of air carries away the second and the third fractions. A rotatable permeable member is arranged to permit the stream of air to pass therethrough and thereby force and retain the third fraction against a surface of the rotatable permeable member and be conveyed, by the rotatable permeable member, toward a third collection area while the second fraction tends to separate, from the rotatable permeable member and the third fraction, and collect in a separate second collection area.

Sieve cleaners (1) for cleaning a sieve surface (2) of a sieve box (3), which sieve box contains a sieve surface (2) and bottom (4). The sieve cleaners (1) contain a wobble foot (5), which extends along a main axis (A) of the sieve cleaner (1) and is designed such that the wobble foot can be placed onto the sieve bottom (4) and the sieve cleaner (1) can be tipped about the wobble foot (5). At least one cleaning element (6) has a cleaning region (7), and each cleaning region (7) has a plurality of cleaning surfaces (8) for cleaning the sieve surface (2). The cleaning surfaces (8) are each designed for at least linear contact with the sieve surface (2) and are separated from one another by slots (9) formed in the cleaning region (7). Sieve units and methods for upgrading or converting a sieve box are also disclosed.

A magnetic separator apparatus for the removal of magnetic particles from gold bearing sands provides one or more magnetic separator assemblies along a sluice box channel to remove the magnetic particles using spinning strong earth magnets within a magnetic separator assembly, removing the magnetic particle where they are removed from the apparatus and evacuated as waste, while the valuable non-magnetic particles are left within the sluice for further separation, classification and processing to remove the precious metal particles contained therein, the apparatus used in a wet or dry application.

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.

A processing equipment for collecting matter adhering to a surface of packages to be processed, the equipment including: a rotary cylindrical drum provided with orifices forming a screen for retaining the packages and for allowing the matter for collection to pass through; a brush roller mounted in the drum in order to brush the inside surface of said drum; a motor for driving the brush and the rotary drum in rotation; an outer casing for collecting the matter that has passed through the wall of the rotary drum during processing; a compression device against the inside face of the drum mounted inside the rotary drum in the immediate vicinity of the inside surface of the drum.

This disclosure relates to a system and device for cleaning impurities, garbage, rocks and etc. from sand. In one embodiment, a sand cleaning device includes a spinning brush head that includes one or more flaps that push sand through a screen while retaining impurities, garbage, and rocks within a receptacle. The system includes a remote power unit for powering the sand cleaning device.
