ABSTRACT:
The improved self-cleaning magnetic separator includes a tube and a conveying flight spiralled about the tube. The separator has a magnetic material collecting portion, a magnetic material discharge portion and a bar-like magnet providing a lobe-like magnetic field. The field is of generally uniform strength along the material collecting portion and diminishes in strength along the discharge portion. In a highly preferred arrangement, the magnet is stationary and the tube and flight rotate with respect to it. Because the magnetic material is "trapped" by the stationary field, such rotation causes the magnetic material to be urged by the flight from the collecting portion to the discharge portion. The field, of diminished strength in the discharge portion, permits magnetic material to fall away from the discharge portion. In one arrangement, the magnet has a shunt for diminishing the field strength to a very low value, zero or only slightly above, thereby configuring the separator for use even with very finely divided magnetic material.
