Selective recovery of metallic scraps using electromagnetic tensor spectroscopy
Abstract
Automobile use continues to show significant increase year on year, with well over 1 billion vehicles now in use globally according to OICA figures. As a result, the recycling of end-of-life vehicles (ELV) has become a major concern, with legislative ELV recycling systems in place in many countries. In the EU for instance, ELV generate approaching 10 million tonnes of waste per year and around 75% of this is currently recycled or recovered, but this percentage falls well short of the 95% target for 2015 set by the ELV European directive. Automobile shredding residue (ASR) includes heavy metals as well as a mass of unclassified fine particles. The non-ferrous metal fraction in ELV scrap contains several metals/alloys; primarily aluminium, copper and brass, whose recovery is important for environmental, economic and resource conservation reasons. The separation of non-ferrous metals from ASR scrap is technically complex and existing technologies suffer from poor cost effectiveness. This paper present a new method for sorting of non-ferritic metallic scrap using electromagnetic tensor spectroscopy. The method combines a vision system, with a novel electromagnetic array to determine the electrical conductivity of each metal piece. The pieces can then be sorted based on conductivity into metal type. Crucial to this process is a fast metal identification algorithm, which allows the line to be operated at conveyor speeds of several m/s and which linearly scales in complexity with conveyor belt width. This study reports that the metal identification algorithms perform adequately when processing machined metal test samples with a wide range of shapes, without the use of any vision information. The challenge is to cope with the diverse range pieces in terms of shape and morphology. In doing so, a A1/4-scale EMTS system has been developed to prove the principle of the technique.
