  1. 6. Comminution control using reinforcement learning : Comparing control strategies for size reduction in mineral processing

    University essay from Umeå universitet/Institutionen för fysik

    Author : Mattias Hallén; [2018]
    Keywords : Reinforcement Learning; Mineral processing; Process control; Comminution;

    Abstract : In mineral processing the grinding comminution process is an integral part since it is often the bottleneck of the concentrating process, thus small improvements may lead to large savings. By implementing a Reinforcement Learning controller this thesis aims to investigate if it is possible to control the grinding process more efficiently compared to traditional control strategies.

  3. 7. Development of a wear index and its methodology related to mineral processing - Part I

    University essay from Lunds universitet/Industriell Produktion

    Author : André Larsson; [2016]
    Keywords : Nanoindentation; Berkovich indenter; wear; surface hardness; rock; minerals; manganese steel; mining; comminution.; Technology and Engineering;

    Abstract : This Master Thesis was performed for Sandvik SRP in collaboration with the Institution for Industrial Production Faculty of Engineering at Lund University. Tool wear is one of the main cost drivers in the mining industry. READ MORE

  4. 8. Energy requirements for comminution of fibrous materials - qualitative chipping model

    University essay from Institutionen för teknik, TEK

    Author : Lukasz Niedzwiecki; [2011]
    Keywords : Biomass; wood; comminution; specific energy; total specific energy; effective specific energy; chipping; chipper; moisture content; hardness; density;

    Abstract : This paper aims to derive qualitative model for energy requirements for wood chipping process. There is relationship shown between energy requirements and properties of biomass, which is quite variable material. Relationship between comminution machinery and energy necessary for the process is highlighted. READ MORE

  5. 9. Prestation vid sönderdelning av GROT med olika typer av maskiner

    University essay from SLU/Dept. of Forest Resource Management

    Author : Daniel Karlsson; [2010]
    Keywords : Krossning; flisning; fraktionsfördelning; tidsstudie; ekonomi;

    Abstract : There is a need for productivities data and data for different types of machines for comminution of logging residues. The lack of data and studies on GROT comminution makes it difficult to evaluate different chains for handling of residue fuels and make system analyses. READ MORE

  6. 10. Buntning av grot med lastbilsmonterad utrustning

    University essay from SLU/Dept. of Forest Resource Management

    Author : Torbjörn Edman; [2009]
    Keywords : biobränsle; grotbuntare; produktivitet; systemanalys; värmevärde;

    Abstract : During the transportation of logging residues (LR) the material´s low density is a problem that results in low use of pay-load capacity. Comminution or compression of LR are possible methods to increase pay-loads. In the present thesis studied a bundling machine which was mounted on a truck chassis, and the subsequent transport and crushing. READ MORE
