New Design Options for Metal Recycling Shredder Hammers and its Reusability
Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
This work’s objective is to analyze hammers failures of a shredder hammer that belongs to a metal recycling company called STENA RECYCLING located at Stockholm, Sweden, recommending different ways to improve performance and useful lifetime. Furthermore, to understand what could be done with shredder hammer after its useful lifetime in a sustainable way, aiming to improve the hammers reusability. The suggested methodology is to do a bibliography research focused on studying different types of head hammer materials’ specifications and designs used on metal recycling. Another objective is to study different possibilities to reuse this kind of hammer after its end of life. In addition, a study case of STENA Recycling company will be done focused on comparing the kind of hammer they current use at the company with other new kinds available at the market. This work will try to analyze if these new kinds could improve hammer’s useful life. The work also tries to show what happens with the used hammers at STENA. Finally, this work intends to identify solutions to avoid the fast wear and short lifetime problems of the head hammers. The purpose of these solutions is to improve the machine’s performance and optimize the metal recycling production and also recognize good ways to reuse the used hammer with as little environmental impact as possible.
