This type of plates are used for extracting metallic particles which circulate on an overbelt during a vertical fall or over a sloping channel, over ramps, etc... It is made from very big ferrite magnets placed in such a way that they create a great magnetic field. The magnet surface that comes in contact with the material that is circulating is made in AISI 304 or AISI 316 stainless steel. These plates have threaded holes in its back piece. The standard range includes a great variety of measurements, however, by special order, we can supply them in any size.
