A rock separator for separating rocks from soil, where the rock separator includes a mounting plate a plurality of elongate tines secured to the mounting plate, where the plurality of elongate tines define a curved shape across the mounting plate, a plurality of support members laterally joining the plurality of elongate tines and an attachment bracket on the mounting plate for releasably mounting to a machine. The mounting plate has a first major surface and a second major surface opposite the first major surface. The attachment bracket is attached directly to the mounting plate, where the plurality of elongate tines do not move relative the attachment bracket.

The invention concerns a sieve device for use in a device for generative manufacture of components by means of successive solidification of individual layers of powdered solidifiable construction material by exposure to radiation through sector by sector melting or fusing and binding of the construction material the sieve device is configured at least in sections to be inclined in a way that the construction material after appearance on the sieve slows or is reduced to a lower velocity over the surface of the sieve.

Provided is a method for removing wire-form objects, a device for removing wire-form objects, and a method for processing electronic/electrical apparatus component waste, which can efficiently sort wire-form objects from sorting target objects having various shapes. The method for removing wire-form objects includes: arranging a filter in a vibrating sieve machine, the filter including a plurality of rods extending at distances in a feed direction of a raw material; and placing a raw material containing at least wire-form objects and plate-form objects onto the filter, and vibrating the filter to sieve out the wire-form objects under a sieve.

A disclosed screen assembly includes a frame and a tensioned molded polyurethane screen attached to the frame. The frame has a perimeter that is a circle, square, rectangle, triangle, pentagon, hexagon, or other multi-sided polygon, and the screen may have similarly shaped apertures. The frame includes a support grid structure bounded by the perimeter and the screen may either be attached only to the perimeter of the frame, or may be attached to the perimeter of the frame and to one or more locations of the support grid structure. The screen may include uniaxial or biaxial reinforcement members that are integrally molded with the screen, and the tensioned screen may include tension along a direction that is parallel to, or perpendicular to, a direction of the reinforcement members. A disclosed method includes applying tension to a molded polyurethane screen and attaching the tensioned molded polyurethane screen to the frame.

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.
