ABSTRACT:
A magnetic separator has a support defining an upright axis, two stationary pole pieces spaced from and around the axis on the support, and a stationary inner ferromagnetic piece extending between the pole pieces and axially bridging same. This inner piece defines with the outer pieces respective angularly offset separation gaps. Means is provided, normally in the form of coils, for energizing the pole pieces and thereby creating a magnetic field extending radially across the gaps and through the inner piece. An annular rotor centered on the axis extends through the gaps. This rotor is formed of an endless angular succession of groups of nonradially extending and spaced-apart rotor elements. It is rotated about the axis to orbit the groups of rotor elements through the gaps and particulate material including magnetically attractable particles is fed axially down through the rotor as it rotates. Particles are then washed from the elements at a location angularly offset from the gaps. The rotor elements are normally wholly nonmagnetic and the rotor-element groups are separated by radially extending walls.
