Patent ID: 8544654

Claim:
A magnetic separator vibratory feeder for separating articles containing a ferrous material from articles which are free of ferrous materials comprising: a set of trays mounted in series with each tray having an input side and an output side and arranged with at least one tray having the output side located above the input side of an adjacent tray located downstream thereof; a vibrator coupled to said set of trays for vibrating said set of trays to vibratorily move the articles containing ferrous materials and the articles which are free of ferrous materials up and down as the articles containing ferrous materials and the articles which are free of ferrous materials move downstream from the output side onto the input side of the adjacent tray; a magnet located proximate at least one of the set of trays for magnetically grasping the articles containing a ferrous material from the articles which are free of ferrous materials as the articles containing ferrous materials and the articles which are free of ferrous materials articles are vibrated proximate a magnetic field of the magnet; and a wiper for removing the ferrous articles from the magnet and the magnet comprises a rare earth magnet vibrationly isolated from the set of trays.
