3 Eichert, Carsten Kernbaum, Sebastian Solenthaler, Christoph 2008 5th CIRP - Life Cycle Engineering, Sydney Hammer Mill, Recycling Technology, WEEE treatment <p> Resource recovery gains more and more importance from an ecological point of view. Keeping resources in cycles includes the collection, transportation, proper environmental friendly pre-treatment and the delivery towards suitable recovery technologies. The recovery of resources of WEEE is often connected with the complete destruction of products and components in shredding machines, which leads to complex and inefficient post-treatment separation and sorting techniques. The hammer mill technology provides an adequate mean to separate fractions for easier post-treatment processes. </p> <p> This paper will present the hammer mill technology applied in WEEE treatment, summarize results gained with the technology from a WEEE treatment plant, concludes its advantages. Additionally, economic results andadvantages are presented. Finally, environmental implications during operation of WEEE in vertical mill are given. </p>
