Metal contamination is a common feature in the wood processing industry. Many panels or chipboard manufacturers use a combination of virgin and reclaimed wood, resulting in high levels of metal contamination. If metal enters a shredder it can spark and this can cause an explosion or a fire. Typical techniques to remove the metal include:
- Permanent Overband Magnets and Electro Overband Magnets are suspended over conveyors and lift larger ferrous metal contamination out of the conveyed shredded wood;
- Drum Magnets and Pulley Magnets provide an enhanced metal separation solution, especially for smaller ferrous metals;
- Eddy Current Separator is important in cleansing recycled wood, separating non-ferrous metals such as door hinges and handles;
- Metal Detectors provide a final check prior to entering a shredder and for the final finished board, usually prior to cutting.
