A separation device having a housing (10) with a feed conduit (1) and a reject conduit (2), between which conduits (1, 2) and an accept conduit (3) of the housing (10) is a rotor unit (13) having a shaft (4) transverse to the through-flow direction of the separation device, which shaft rotates discs (5) attached to the shaft (4), the outer surface and/or side surfaces of which discs are jagged, i.e. they have protrusions (6) and/or notches and/or these surfaces are substantially rough and the teeth (9) of at least two sieves (7, 8) attached to the housing (10), extend between the discs (5), the first sieve (7) being between the reject conduit (2) and the accept conduit (3) and the second sieve (8) being between the feed conduit (1) and the accept conduit (3).

Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. Shredded matter, or ASR, is sent through a series of sorters before reaching a system that separates out copper bits. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper.

A method of recycling scrap is disclosed, comprising the steps of shredding the scrap with a shredder into shredded scrap objects, classifying the shredded scrap objects into fractions of scrap objects having different size ranges with a classifier, and sorting scrap objects while substantially maintaining interspace between the objects. Further, a singulating arrangement for singulating scrap objects is disclosed, comprising a substantially horizontally disposed feeder that extends from a receiving area for receiving scrap objects to a feed gate positioned at a top portion of a chute, as well as an ejector arrangement, comprising a conveyor with a substantially flat conveying plane and an ejector device disposed along the conveyor.

An aggregate processing assembly is provided. The processing assembly includes a separator assembly having a central member extending from a first end to a second end, the central member supporting at least one helical flight provided between the first and second ends, the helical flight having a width provided between a proximal end and a distal end. An assembly housing is provided around a portion of the separator assembly, the assembly housing includes a collection portion for receiving processed feed stock which exits the separator assembly radially away from the central member outward past the distal end, and the collection portion includes a first outlet. A second outlet is coupled to the separator assembly for receiving processed feed stock which exits the separator assembly at the second end of the at least one helical flight. A proppant, an aggregate, a system for processing feed stock to produce a proppant or aggregate, and a method of producing a proppant or aggregate is also provided.

Apparatus (200) for sorting mixed waste materials, comprising: a housing (260) configured to be vibrated to assist sorting; a screen (210) supported by the housing (260) and having an inlet end (212) for receiving waste materials and an outlet end (214) for discharging at least some waste received at the inlet end (212), the screen (210) comprising at least one portion (220) pivotally coupled adjacent the inlet end (212) to a substantially horizontal axle (222) mounted in the housing (260); and drive means (224,228) configured to pivot the at least one portion (222) of the screen (210) about the axle (222) with a controlled reciprocating action.

A system and method for selectively filtering abrasive particles for a cutting machine serves to filter variously shaped and dimensioned abrasive particles into a hopper through use of multiple, interchangeable screens. Each screen forms multiple openings defined by a shape and dimension, and each screen has a unique shape and dimension. A pneumatic variable speed motor vibrates the screens at variable speeds, depending on intensity of air flow through an air inlet. The sieve subassembly has a main base and containment ring. A two-piece split clamp ring sandwich the perimeter region of screens. From the hopper, a flow of high-pressure air carries the filtered abrasive particles to a waterjet cutting machine. The filtered abrasive particles are mixed with high pressure water to cut a workpiece. The shape and dimension of the abrasive particle is determinative of the type of workpiece to be cut.

A method for recovering metals from waste in which material is roughly or coarsely separated to leave a fibrous feedstock, the feedstock is comminuted with a mill (e.g., a ball mill) to liberate and separate the fibrous feedstock to obtain a mix of a metal fraction and residue, and the metals fraction and the residue are collected. There is a system employing the same to treat such materials.
