DebTech developed the MagRoll for the diamond industry and it has the potential to be used by more mineral processing industries e.g. mineral sands, iron ore and platinum. There are interchangeable magnetic rolls of different designs to suit specific applications. A vibrating feeder draws material from a feed hopper and feeds it at a controlled rate onto a rotating conveyor belt, which passes over a magnetic head pulley. Non-magnetic material follows a trajectory, which is uninfluenced by the magnetic pulley’s field, however the magnetic material is drawn towards the pulley and discharges with a different trajectory. Material remain secure within the machine. A collection hopper fitted below the durable conveyor collects the discharging ‘magnetics’ and ‘non-magnetics’ streams. Efficient separation is achieved over a wide range of particle sizes from -1mm to 25mm.
