An apparatus for sorting crop components comprises a tabletop having a top and a bottom surface and an outer edge therearound, an inner edge spaced inwards and apart from the outer edge of the tabletop and a lower surface parallel to and spaced apart from the tabletop. The apparatus further comprises at least two spaced apart apertures extending through the lower surface with angled walls extending down from the inner edge to the lower surface and a plurality of vertical table legs supporting the tabletop.

A method of shape sorting abrasive particles involves disposing initial crushed abrasive particles with agitation against the surface of a tool, the surface defining a plurality of shaped cavities having an average aspect ratio of at least 1.2, thereby causing a first portion of the initial crushed abrasive particles to become retained within at least some of the shaped cavities, and causing a second portion of the initial crushed abrasive particles to remain as loose particles on the surface. Substantially all of the shaped cavities contain at most one abrasive particle. The second portion of the initial crushed abrasive particles is separated from the tool. The first portion of the initial crushed abrasive particles is then separated from the tool and isolated as loose sorted crushed abrasive particles. The average aspect ratio of the loose sorted crushed abrasive particles is greater than that of the initial crushed abrasive particles.

A material sorting system sorts materials utilizing a vision system that implements a machine learning system in order to identify or classify each of the materials, which are then sorted into separate groups based on such an identification or classification determining that the materials have a specified geometric shape. Such a system can sort monetary coins or other valuable metals from other forms of scrap.

Systems and methods for increasing recyclable material recovery from automobile shredder residue (4). Embodiments include separation of automobile shredder residue with a sorting system (5) such as an air sorting system, a non-ferrous automobile shredder residue air sorter, an air-locked automobile shredder residue sorting system, a non-magnetic magnetic sorter, a substantially isotropic quantization sorting system, an air-locked Z-box air classifier, low susceptance microparticle separator, a magnetic fuzz separator, a wind tunnel system, or the like perhaps with substantially horizontal laminar air flow (7) and can be used with or without out other traditional automobile shredder residue sorting systems (16) or (15) perhaps creating additional recyclable quantities and even better separated results such as with zorba and zurik and the like.

A stone sieve assembly includes a cutting blade, a back plate, and a plurality of bars. The plurality of bars are spaced apart from one another and extend between the cutting blade and the back plate. The plurality of bars have a leading section positioned proximate the cutting blade and a trailing section positioned proximate the back plate. The trailing section tapers inwardly as it approaches the back plate.

The invention relates to a method comprising a device (1) having at least two separating surfaces (2, 2) for separating planar and three-dimensional solids, which can be light, medium, and heavy, wherein the device can be installed and integrated into existing system for separating different material streams, such as garbage and waste. The bulk goods (3) to be separated and fed first to a first separating surface (2), and then to a second separating surface (2) in succession, whereby a high degree of separation between light and heavy bulk goods (3) is achieved.

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.

Disclosed herein is a system for detecting, removing, transferring and recovering an incompletely dried material. The system includes a transfer device transferring the material subjected to a drying process, a load cell measuring a weight of the material transferred through the transfer device, a material receiving unit receiving the measured material from the load cell when the weight of the measured material is higher than weights of other materials or a preset reference weight, a thermal imaging camera photographing the material received by the material receiving unit, an incompletely-dried-material determining unit acquiring temperature information of the material photographed by analyzing image data photographed by the thermal imaging camera, and determining whether the photographed material is an incompletely dried material based on the acquired temperature information, and an incompletely-dried-material receiving unit receiving the incompletely dried material from the material receiving unit.

A method for producing a powdered starting material, which is provided for production of rare earth magnets, including the following steps: pulverizing an alloy, including at least one rare earth metal, wherein a powdered intermediate product is formed from the alloy including at least one rare earth metal, and carrying out at least one classification aimed at particle size and/or density for the powdered intermediate product, wherein a fraction of the powdered intermediate product, which is formed by means of the at least one classification, for fabrication of rare earth magnets. Furthermore, at least one dynamic classifier is provided, implementing at least one classification directed at particle size and/or density for the powdered intermediate product and thereby separates the fraction from the powdered intermediate product, which forms the starting material provided for manufacturing rare earth magnets.

Two methods or apparatuses for separating two enantiomorphs of a chiral object. First, the apparatus includes a bended channel, for which the first opening is the orthogonal projection of one enantiomorph in a certain orientation, and the second opening is a different orthogonal projection of the same orientation. At the bend, the channel surface is complementary to the three-dimensional shape of the enantiomorph, which permits one enantiomorph to pass through the second opening, but blocks the other enantiomorph. Second, the apparatus includes a single asymmetric opening that is a small orthogonal projection of the chiral object. Both enantiomorphs of the chiral object can pass through the opening by manual manipulation. By free falling, one enantiomorph will pass through while the other will be blocked. These separation apparatuses are applied to toys, puzzles, and educational tools.
