1. 1. Mineral wool : From landfill to a sustaianble polymer composite

   University essay from Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)

   Author : Noéll Sjöbeck; [2022]
   Keywords : recycling; sustainability; waste management; circular economy; mineral wool; construction and demolition industry; composites; polymers; återvinning; hållbarhet; avfallshantering; cirkulär ekonomi; mineralull; bygg- och rivningsindustri; kompositer; polymerer;

   Abstract : The focus of the project is recycling of the insulation material mineral wool. The aim is to investigate the potential of using post-consumer wool from landfill as fiber reinforcement in a polymer matrix. READ MORE

3. 2. Effect of post-treatment of cemented carbide : Microstructural investigation and evaluation of mechanical properties of cemented carbide inserts for rock tool applications

   University essay from Karlstads universitet/Avdelningen för maskin- och materialteknik

   Author : Jessica Jacobs; [2021]
   Keywords : ;

   Abstract : Cemented carbides are used in rock tool applications by reason of their beneficial mechanical properties, i.e. a combination of high toughness, wear resistance and hardness. The cemented carbides commonly receive their hardness from tungsten carbides (WC) whereas cobalt (Co) is the dominating binder material. READ MORE

   Abstract : This Master's thesis project was provided by Epiroc Rock Drills AB and conducted at Camatec Industriteknik AB in Karlstad, Sweden. The project is centered around the cutter wheel in the mechanical rock excavator Mobile Miner 40V. READ MORE

6. 5. Load modelling of a mobile miner

   University essay from KTH/Strömningsmekanik och Teknisk Akustik

   Author : Rafail-Nikolaos Dimitriou; [2020]
   Keywords : ;

   Abstract : In the mining industry, finite element analysis (FEA) and experimental tests are essential for the verification of mechanical properties and for performing parametric studies. Such practices require lots of resources and, sometimes, long computational time. READ MORE
