Abstract

See full text

A ferro-magnetic material recovery system includes a drum rotating within a magnet housing. An array of magnets mounted within the magnet housing have corresponding magnetic fields which decrease in strength in the direction of rotation of the drum to extract the material from a slurry flowing through the drum. Flow deflectors may be mounted in the drum. The array of magnets may form a magnetic core having magnetic fields that are radially aligned.
