<p>Tyres are de-metallised by passing them on a conveyor 5 through a high frequency induction coil 2 which is surrounded by an enclosure 6. As each tyre passes through the coil 2 its metal wires are melted by the coil 2, the molten metal then falling into a tray at the bottom of the enclosure 6 and the remaining rubber portion of the tyre being removed from the coil 2 by the conveyor 5. The enclosure 6 contains water 7 in which at least a part of the conveyor 5 is submerged so that at least a part of each tyre is submerged as it passes through the coil 2. By surrounding the coil 2 with the enclosure 6 and using water 7, pollution and the risk of fire are reduced. The rubber can be reprocessed for other uses.</p> |
