Metal Separator for Copper and Stainless Steel

The project's background is based on a task from the company Danfoss. Danfoss’ objective was to find a solution for sorting scrap metal. The task was to find a solution or possibly invent a new solution for the separation of waste. However the project was carried out independently of Danfoss, as they have received a short report in which they have found all the information they need and confirmed that report. This project includes a more thorough examination, both theoretical and practical, of solutions for the sorting of copper and stainless steel. The investigation demonstrated a practical way of separating these two metals based on their electrical conductivity. The equipment used for the separation was based on eddy current separator theory. This separator was selected as the final solution to sort copper from stainless steel. Results of research conducted in the laboratories of Russia and China have been carefully analysed and corresponding conclusions have been made. Part of the project’s research included a market analysis and a description of some commercially available systems is also presented in this thesis. As a result the solution described in this thesis can be used in any factory where stainless steel and copper are the waste products
