ABSTRACT:
A magnetic separator includes a plurality of elongated magnetic members generally disposed with longitudinal axes extending in parallel relationship with one another. A first end plate is connected to adjacent terminal ends of the magnetic members to hold the magnetic members with the longitudinal axes generally defining a common plane. Non-magnetic sheathing members are disposed sheathing the entire longitudinal length of the magnetic members. A second end plate is connected to adjacent terminal ends of the non-magnetic members to provide longitudinal sheathing and unsheathing movement of the sheathing members with respect to the magnetic members for cleaning accumulated magnetic particles from the exterior surface of the non-magnetic members. The first and second end plates are adapted for reciprocating movement in the commonm plane, preferably in a direction generally perpendicular to the longitudinal axes of the magnetic members to reduce bridging and clogging of the material flow. In a preferred embodiment, first and second sets of elongated members are arranged in first and second parallel planes. The longitudinal axes of the magnetic members are disposed generally partallel to one another and staggered with respect to one another in a direction of material flow generally perpendicular to the first and second planes. The first set of magnetic members are oscillated in a direction within the first plane opposite to the direction of oscillation of the second set of magnetic members within the second plane.
