The final opportunity for removing or detecting metal contamination is at the packaging stage. At this point, there are two opportunities to ensure that the finished product is metal-free.
- As the product is being packed, Magnetic Separators such as Tube & Grid Magnets, Plate Magnets, and Bullet Magnets can be positioned in the process to capture tramp iron;
- In some cases, where materials are being conveyed prior to packing, Overband Magnets can be installed over the belt, the conveyor head pulley can be replaced with a Pulley Magnet, or a Magnetic Drum can be built into the line. All these are self-cleaning designs;
- As a final step, the packed material can be passed over or through a Metal Detector. This will detect any metal contamination and allow removal and recycling;
