The Fornnax Drum Magnet retrieves leftover steel wires from rubber granules with less than 30mm particle sizes in tyre recycling. As the material reaches the Drum Magnet, the magnetic field attracts the Ferrous particles and holds them onto the drum shell. The drum’s rotation causes the material to move through the stationary magnetic field. The non-magnetized material falls away from the shell, but the ferrous particles are held firmly until removed from the magnetic field.
