    摘要： A drum-like rotor having numerous, closely spaced, elongated rows forms of permanent magnets arranged end-to-end and secured to the outer surface of the rotor, produces a high-density, rapidly reversing magnetic field in a band-like zone which is spaced a short distance from,and extends along the length of,the rotor outer surface. The magnetic field induces eddy currents in pieces of different metals passed through the zone which produces repulsive magnetic forces of different intensities in different metal pieces, and thus, magnetically separates such pieces. The rows of magnets, in their radial direction, are alternatingly thicker and thinner,so that the outer surface of the thinner rows are depressed relative to their adjacent thicker rows. The outer surface of the magnets of each thicker row have a polarity which is opposite to the polarity of their next adjacent thicker row magnets, and the direction of the magnetic polarity of the magnets of the thicker rows are radial relative to the rotor. The side edges of the magnets of the thinner rows have the same polarity as the polarity of the outer surfaces of their adjacent thicker row magnets. The directions of the magnetic polarity of the thinner row magnets are generally circumferential, relative to the rotor. Thus, magnetic flux flows transversely through each of the thinner row magnets and then radially outwardly through their adjacent thicker row magnets, returning over the exposed surfaces of the thinner row magnets to the next adjacent row of thicker magnets and, therefore, radially inwardly of the rotor and transversely of the thinner row. Thus, the direction of the magnetic flux flow through the zone changes as the successive thicker and thinner rows pass alongside of the zone as the rotor rotates.

    摘要： Mixed pieces of different non-ferrous metals are sorted by initially moving the pieces through a high density, rapidly changing magnetic flux field, and immediately thereafter, freely moving the pieces along unsupported forwardly and downwardly directed trajectories resulting from the momentum of the pieces, the force of gravity and the magnetically induced repulsive forces developed in the pieces by the flux field. The magnitude of the magnetically induced repulsive forces differ for different non-ferrous metals so that the lengths of the trajectories of generally similar size and shape pieces vary accordingly for separating pieces formed of different metals. The magnetic field is provided by a horizontally axised, rapidly rotating, hollow, liquid cooled, iron wall drum having magnets affixed to its outer surface. The magnets are arranged in rows that are formed of numerous, tile-­like, small, permanent magnets which are positioned end to end, with their like polarity ends adjacent. A belt conveyor, which moves the pieces across the top of the drum, has its discharge end pulley coaxially surrounding the drum so that the pieces freely move off the end of the conveyor belt after passing through the magnetic field. Hence, the lengths of the trajectories may be controlled by adjusting the speed of the conveyor, which adjusts the momentum of the pieces, and by adjusting the rotational speed of the drum for adjusting the frequency of the changes in the magnetic field and, consequently, the magnitude of the induced repulsive forces.

    摘要： A system and a method of sorting scrap particles includes imaging a moving conveyor containing scrap particles using a vision system to create an image. A computer analyzes the image as a matrix of cells, identifies cells in the matrix containing a particle, and calculates a color input for the particle from a color model by determining color components for each cell associated with the particle. A light beam is directed to the particle on the conveyor downstream of the vision system, and at least one emitted band of light from the particle is isolated and detected at a selected frequency band to provide spectral data for the particle. The computer generates a data vector for the particle containing the color input and the spectral data, and classifies the particle into one of at least two classifications of a material as a function of the vector.

    摘要： An eddy current separator (10, 10a, 10b, 10c, 10d, 10e, 10f, 10g) and a separation method for separating non-ferromagnetic particles (14) by engaging the particles to force the particles into a primary magnetic field (34) to increase the induced eddy current flow that generates particle magnetic fields such that subsequent release of the particles allows increased magnetic field propulsion to propel the particles distances that vary according to their electrical resistance, densities, shapes and sizes. Different embodiments move the particles into the primary magnetic field by an inclined engagement member (42) that may be a flexible member (42') or a brush (42''), a vertically movable roll (54a), a rotary brush (54b), an upper auxiliary conveyor (64), an upper belt reach (26) of a belt conveyor (16), a vibratory member (26') of a vibratory conveyor (16'), and an inclined gravity slide (70) that may be a curved trough (72).
