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.

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 self cleaning collecting apparatus and method are provided for the collection of seafloor material. The collecting apparatus, which operates on a seafloor, has a plurality of rotating discs in front of a slurry suction pipe with clearing members located between adjacent discs. Any oversize material lodged in the discs during collection is dislodged by the one or more clearing members and prevented from entering the slurry suction pipe, thus preventing blockages caused by oversize material congesting the slurry suction pipe.

A cleaning device for a sieve box is provided. The cleaning device can include outer members configured together to form a perimeter, a central region located within the perimeter and interior members connecting the perimeter and the central region. The cleaning device can include nubs provided on the bottom surface of the outer members and the interior members. The nubs can be spaced apart across the lengths of the outer and interior members and can include terminal ends. The terminal ends of the nubs can have rounded, flattened or pointed shapes based on the intended aggressiveness of the cleaning device. The cleaning device can be adapted for placement on a sieve screen of the sieve box and move across the sieve screen to remove milling product stuck to the sieve screen, break apart clumped milling product, and/or push excess milling product toward a discharge zone of the sieve box.

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.

A scalper apparatus configured to divide a flow of material between filtered and unfiltered streams. The scalper apparatus may include a housing with an upper opening, a primary lower opening for outputting the filtered stream, and a secondary lower opening for outputting the unfiltered stream. The scalper apparatus may include a grate extending across the interior of the housing such that any material leaving the interior through the primary lower opening must pass through the grate while any material unable to pass through the grate is caused to move through the secondary lower opening. The scalper assembly may include a brush assembly with at least one brush movable across the grate, and a carrier assembly configured to carry the at least one brush across substantially an entire top of the grate.

A sieve frame, including: a sieving component arranged in a horizontal direction; a support component arranged below the sieving component, spaced apart from the sieving component, and disposed parallel to the sieving component, the support component including a plurality of openings; a cleaning component arranged between the sieving component and the support component, supported by the support component, and used to clean the sieving component; and a bottom plate arranged below the support component, the bottom plate including an inclined surface inclining relative to the horizontal direction and a material discharging port arranged on a side edge of the bottom plate, and the inclined surface extending to the material discharging port. A sieving device is further included. The sieve frame and the sieving device exhibit high material discharging speed, and the sieve frame provides a high yield. The device has a reduced size and a reduced footprint.

To provide a building material manufacturing apparatus that is suitable for suppressing clogging of a screen that screens a building raw material.

A building material manufacturing apparatus X1 includes at least a screen part 10 and a cleaning mechanism part 40. The screen part 10 includes at least one screen sheet 12 that has an inclination and that has a screen mesh. The cleaning mechanism part 40 includes a scraping part 40a. When the apparatus operates in a building material manufacturing mode in which a building raw material M is supplied to the screen sheet 12 and the screen sheet 12 is performing a wave motion, the scraping part 40a is separated from the screen sheet 12, and, when the apparatus operates in a cleaning mode in which the building raw material M is not supplied to the screen sheet 12 and the screen sheet 12 is not performing a wave motion, the scraping part 40a rotates in contact with the screen sheet 12.
