Abstract
The arcuate magnet is made up of a series of magnets that produce a radial shape magnetic field. The arcuate magnet is supported adjacent the outer periphery of the cylindrical blind trommel. The blind trommel is rotated. Steel balls and magnetic material are held to the inner periphery of the blind trommel and carried with it to the end of the arcuate magnet. The arcuate magnet may be made up of either electromagnets or permanent magnets. Another embodiment has one or more magnets attached to spaced positions around the outer periphery of the trommel. Permanent or electromagnets may be employed. Electromagnets are connected to slip rings that energize the magnets from about the 6 o'clock position and de-energize the magnets at about the 11 o'clock position. The permanent magnets are moved away from the blind trommel at about the 11:00 o'clock position. The magnetic material is released from the blind trommel at about the 11:00 o'clock position and collected in a tray inside the blind trommel. One magnet or a plurality of magnets can be used.
