Suspension Magnets are used when only small contamination levels are encountered. The material accumulated on the pole face must be removed at regular intervals. When stopping the plant and in case of power failure, the iron drops back into the material to be conveyed.Overband Magnetic Separators are used when substantial quantities of magnetic material and or long bulky pieces are contained in the conveyor burden. This material is attracted by the magnet and is transported out of the magnetic field and ejected by the discharge belt running around the magnet.
