摘要： The disclosed eddy-current separator has several new features. One includes a magnet assembly which is metal-sleeved for protecting the magnets from impact by particles or objects piercing the waste-carrying conveyor belt with which the separator is used. A low-rotating-speed epoxy-layered shell surrounds the sleeve for additional protection. A conveying extension carries ferrous "fines" from the conveyor into the receptacle used to collect waste from which non-ferrous material has been separated. Such extension permits such fines to be under the substantial influence of the magnet assembly over an arc well less than 180.degree.. The conveyor belt uses relatively-closely-spaced cleats of reduced height to reduce the "loading" of an individual cleat with potentially-piercing ferrous fines. A two pole magnet assembly may be used and/or a magnet assembly in which the magnet pole faces are curved for air gap reduction.

摘要： The eddy current separator apparatus disclosed herein employs first and second cylinders, each of which is provided with means for generating a circumferential series of radially directed magnetic poles of alternating polarity. The cylinders are mounted for rotation around parallel axes with an essentially vertical gap between them. A mixture of electrically conductive and non-conductive particles can be fed into the gap from one side. The cylinders are rotated synchronously in opposite directions with poles of opposite polarity facing across the gap, at a speed substantially higher than the speed of mixture feed. Electrically conductive non-magnetic particles are impelled by eddy currents generated by the magnetic flux projected across the gap by the faacing moving poles and can be received or collected separately from free falling non-conductive particles.

摘要： An apparatus for separating a nonmagnetic conductive material from a nonmagnetic nonconductive material. The separation apparatus comprises a drum arranged in a tilted fashion and rotating in one direction about the longitudinal central axis and a chute for throwing a material being separated into the drum from the upper opening thereof. The material supplied through the chute into the drum is agitated by rotation of the drum, and the nonmagnetic conductive material of the material thus supplied into the drum receives an electromagnetic force produced by a magnetic field moving in a direction opposite to the direction of rotation of the drum, so as to be separated from the nonmagnetic nonconductive material. In order to increase the agitation effect for the material supplied into the drum, the chute is biased from the center of the upper opening of the drum to one side of the center depending on the rotational direction of the drum, and shoulder portions are provided on the inner peripheral wall of the drum.

摘要： A nonmagnetic conductive material separating apparatus designed for separation of conductive material from non-conductive material, comprising a drum composed of nonmagnetic substance and rotated in one direction around its longitudinal center axis, and means for generating a magnetic field rotated in the direction reverse to that of the drum. Composite input material posterior to previous removal of magnetic substance therefrom is introduced into the cylinder, and the nonconductive material contained in the entire input material is directed to the rotational direction of the drum along the inner wall thereof, while the conductive material is directed to the reverse direction by the electromagnetic force of the rotating-field generating means.

摘要： A continuous flow magnetic separator is disclosed for classifying magnetic and paramagnetic particles as concentrate from their mixture with ambient tailings. The separator includes a helical classifying path interior of a non-magnetic, non-conductive conduit, with the conduit wound along a path having an "uphill-downhill" slope with respect to the ambient gravitational bias. A magnetic field (preferably generated by an AC or DC energized coil) is aligned substantially coincident to the axis of generation of the helical path. This magnetic field is confined interior of a high permeability (preferably laminated) magnetic field conducting core having two elements. The first element, to which the coil is attached, is an outer cylindrical conductor (preferably closed at the bottom) defining interiorly thereof a cylindrically shaped inner volume. The second element is a cylindrical rotor having serrated edges and mounted for rotation about the axis of the helical path. The rotor defines between the outer cylindrical conductor and its rotating serrated edges a cylindrical gap into which the helical classifying conduit is placed. Particles to be classified are placed into the helical classifying conduit medially between the concentrate output at the upper end of the helix and the tailings output at the lower end of the helix. Upon rotation of the rotor to wind the magnetic and paramagnetic particles "uphill", a concentrated magnetic field at the serrated edges winds the magnetic concentrate in the helical classifying path to the concentrate output. The tailings move in opposition to the concentrate, gravitationally moving on the downhill slope of the helix through the conduit to the tailings output.

摘要： A technique of removing electrically conductive nonmagnetic particles from a stream of material by a cylindrical magnet driven by a conveyor belt carrying the stream of material wherein attractor windings are provided in conjunction with excitation windings for forming zones of attraction of electrically conductive non-magnetic particles to the magnet. Electrically non-conductive and non-magnetic particles are thus not attracted to the magnet and are free to follow a different path than are the electrically conductive non-magnetic particles. Separation is thus achieved between them.

摘要： Methods and systems for recycling a printed circuit board (PCB). The printed circuit board is exposed to a swelling agent that causes an epoxy matrix of the printed circuit board to swell and disintegrate into particles. The particles of epoxy are then separated from the printed circuit board, leaving behind reinforcing fiber and metal containing components thereof. These remaining components are separated from each other and recycled separately using suitable processes. The epoxy particles are also recovered, and may be reduced to a monomer for use in synthesizing new epoxy. The swelling agent includes a carboxylic acid, preferably formic acid, as an active ingredient.
