Abstract:
A system for removing ferrous materials from a flow of non-ferrous materials, the flow being defined by a duct having a pair of generally parallel sides and a bottom, the duct confining the flow of non-ferrous materials along a flow path axis, the system comprising:a pair of enclosures having sides, at least one side of the enclosure being adapted for mounting against the sides of the duct; each enclosure containing at least two magnets that provide magnetic flux, the magnets being mounted within said enclosure, said magnets being retained within said enclosure and spaced apart from one another, and a piece of ferrous material extending between the magnets to provide a flow path for the magnetic flux between the magnets, so that the magnetic flux is focused along an axis extending between the magnets; means for supporting the enclosures together with said magnets against opposite sides of the duct, so that the axis of focus of magnetic flux from each enclosure extends in a generally coaxial manner from the opposite sides of the duct and at an angle to the flow of non-ferrous material when the enclosures are supported from opposite sides of the duct.
