Suspension magnet DND-MC E sits above a conveyor carrying material and as the material passes under the magnet, ferrous metal is attracted up and out of the non-magnetic burden. The magnetic attractive force of an electro suspension magnet is stronger at distance with a higher magnetic gradient (attracting and extracting smaller ferrous metals) than a permanent design. That is why the electro suspension magnets are preferable for the separation of tramp iron in the form of nuts, bolts and ferrous metal blasting caps. Besides, when there is a deep burden of conveyed material, high magnetic forces are needed to extract the ferrous metal from underneath the non-metallic material and the electromagnets are able to cope with this task. And for applications where the suspension magnet requires switching off, the only option is the electromagnetic version, where the magnetic field is easily switched on and off.
