An elongate capping is arranged to support cross-tensioned or pre-tensioned screening media at a screen deck. The capping includes a pair of arms to grip a carrier beam of the screen deck and a head attached to the arms via a neck. The head includes flexible widthwise extending flanges that are configured to bend and compress towards the arms to support the screening media when mounted on the head under tension.

Systems and methods for separating harvested crop product from twigs, dirt, dust, and other debris. A disk to be used in a harvester includes a first segment and a second segment and is configured to cooperate with adjacent disks axially mounted on a common rotational shaft, and radially cooperate with disks mounted on a parallel rotational shaft. The disks are used in a roller assembly or a harvester, and gaps between cooperating disks remain effectively constant during operation.

System, method and/or apparatus repairs an area of damaged mesh in a sifter screen (80). Such sifter screens (80) have woven wire mesh (81) stretched, tensioned and/or secured over a supporting frame (85) having cells (82). Damage occurs to the mesh (81) over certain cells (82). A plug (10) having a mesh layer (14) inserts and/or locks into place in the damaged cell (89). The mesh layer (14) of the plug (10) is flush with the mesh (81) on the sifting screen (80). Ridges (62) and/or ledges (66) secure the plug (10) in place by engaging a lip (96) in the damaged cell (89) to snap-fit the plug (10) in place.

A vibratory apparatus includes a deck assembly with a longitudinal axis, an inlet end, and an outlet end. The deck assembly includes a plurality of deck sections each having a plurality of openings. Each deck section has upstream and downstream edges, the downstream edge of each successive deck section disposed closer longitudinally to the outlet end than the downstream edge of each preceding deck section. The upstream edge of each successive deck section is disposed closer longitudinally to the upstream edge of each preceding deck section than the downstream edge of the preceding deck section is disposed to the upstream edge of the preceding deck section, thereby defining an overlapping portion of the preceding deck section and a non-overlapping portion of the preceding deck section. The overlapping portion has larger openings than the non-overlapping portion for each preceding deck section.

A stem screening and conditioning device includes a roller, a thermal insulation cover, a spiral feeding device, a compressed-air cleaning device, a steam tube, a discharge hole, and a waste hole. A stem screening and conditioning method for the stem screening and conditioning device is also provided. The present disclosure realizes the complete separation of normal-size and undersized stems under the premise of full moisture absorption, thereby improving the refinement and homogenization level of stem conditioning.

The invention relates to a process for producing superabsorbent polymer particles, comprising surface postcrosslinking, classifying the surface postcrosslinked superabsorbent polymer particles, deagglomerating the separated oversize fraction using a roll crusher and recycling the disintegrated oversize fraction before or into the classification of the surface postcrosslinked superabsorbent polymer particles.

A method of valuation of raw fines materials, comprising selectively screening, biotreatment or composting of raw fines materials or selection as fillers in composites. The method comprises screening the raw fines materials to Grade 1 comprising fines materials of a size of at most about 5 mm and Grade 2 comprising fines materials of a size larger than about 5 mm; and at least one of: A) bio-oxydating organic contaminants of the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions and monitoring a content of organic contaminants until the content of organic contaminants stops decreasing; and B) composting the Grade 1; by adding and mixing organic amendment under controlled temperature, nutrients content and water content conditions, and monitoring pathogens content and respiration rate; and stopping the addition of organic amendment upon detection of absence of pathogens at a predetermined respiration rate.
