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.

Systems and methods for low gravity size sorting, conveying and delivery of regolith in flow rate-controlled streams that are movable and can function under terrestrial gravity conditions or at gravity levels as low as zero-G. Utilization if in-situ regolith and planetary, lunar or NEO surface ISRU operations involve selection or creation of size appropriate material for subsequent processing. Movable (articulated auger conveying lines deliver sorted feedstock to specific adjustable endpoints.

A system for grinding material in a material flow through the system may include a feed hopper having an interior for receiving material to be processed, a feed apparatus configured to receive material of the material flow from the feed hopper and control a feed rate of the material moving through the system, a roller mill apparatus configured to grind material of the material flow passing through the roller mill apparatus, and a classifier apparatus configured to remove portions of the material from the material flow.

A grain-cleaning machine for obtaining grains has a desired size which is greater than a lower value and less than or equal to an upper value. The grain-cleaning machine comprises an arrangement of sieves. The arrangement of sieves comprises at least two main sieve levels positioned overlapping each other. Each main sieve level comprises a respective fine sieve followed by a respective grain sieve. At least one lower sieve level comprises a respective lower grain sieve. The at least one lower sieve level being positioned below the main sieve levels. Each fine sieve has a first mesh provided with openings having an opening size which is equal to said lower value, and each grain sieve and each lower grain sieve have a second mesh provided with openings having an opening size which is equal to said upper value.

The invention proposes a grain-cleaning machine (10) comprising an envelope (12) with an inlet opening (13), an arrangement of sieves inside the envelope (12) and a vibration system designed to cause the sieve arrangement to oscillate. The sieve arrangement comprises at least two main sieve levels (14a, 14b, 14c) arranged the one above the other, with an inclination relative to the horizontal from a high side (L1) to a low side (L2), each main sieve level (14a, 14b, 14c) comprising respective fine sieves (141) followed by respective grain sieves (142), and under each fine sieve (141) respective fine-carrying channels (143) are arranged in communication with at least one outlet (18) for residues smaller than the grains, whereas under each grain sieve (142) respective grain-carrying channels (144) are arranged in communication with at least one grain outlet (19). The sieve arrangement further comprises at least one lower sieve level (16) with respective lower grain sieves (162), and under the lower grain sieves (162) respective lower grain-carrying channels (164) are arranged in communication with at least one grain outlet (19). The lower sieve levels (16) are arranged under the respective main sieve levels (14a, 14b, 14c) with an inclination relative to the horizontal from a high side (L3) to a low side (L4), wherein the low side (L2) of each main sieve level (14a, 14b, 14c) is in communication with the high side (L3) of the respective lower sieve level (16) through a vertical passage (17), and the low side (L4) of the lower sieve level (16) is in communication with at least one of the outlets (20) for residues larger than the grains.
