  2. 1. Physical characterization of coarse clasts with 3D image-analysis method : development, evaluation and application

    Author : Solomon Tafesse; Joanne Fernlund; Mark Johnson; KTH; []
    Keywords : 3D image analysis; Particle angularity; Sieve analysis; Particle form; Gravel analysis; Repeatability; Lithological distribution;

    Abstract : This thesis presents a novel three dimensional (3D) image-analysis method for characterizing the physical characteristics of coarse particles in the field, and introduces new methodology for the total analysis of glacial till samples.The novel image analysis method, called the GID method, is capable of determining the size, shape and surface texture of each individual clast analysed.

  4. 2. Estimating particle size distributions based on machine vision

    Author : Tobias Andersson; Anthony Maeder; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Abstract : This thesis contributes to the field of machine vision and the theory of the sampling of particulate material on conveyor belts. The objective is to address sources of error relevant to surface-analysis techniques when estimating the sieve-size distribution of particulate material using machine vision. READ MORE

  5. 3. An investigation into some aspects for foamed bitumen technology

    Author : May Namutebi; Björn Birgisson; Alvaro Guarin; Umaru Bagampadde; Baoshan Huang; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Foamed bitumen; Binder ageing; Aggregate coating; Compaction; Mix design; Aggregate porosity; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Despite applications of foamed bitumen technology in pavement construction in various places around the world, there are still several aspects about this technology that are not clear. In addition, knowledge on foamed bitumen technology is mainly empirical and lacks scientific basis. READ MORE

  6. 4. Comparative Study of Chemical Additives Effects on Dry Grinding Performance

    Author : Vitalis Chipakwe; Saeed Chehreh Chelgani; Jan Rosenkranz; Tommy Karlkvist; Kirsten Claire Corin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Energy; Grinding aid; Flowability; Dry grinding; FT4 Powder Rheometer; Surface properties; Mineral Processing; Mineralteknik;

    Abstract : The application of chemical additives, known as grinding aids (GA), dates back to 1930 in the cement industry. As opposed to the cement industry, where the use of GAs is on the final processing step, it could be one of the first process steps in ore beneficiation. READ MORE

  7. 5. Separation of plastics by flotation

    Author : Huiting Shen; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : This thesis analyses and summarises the importance of plastics waste recycling and plastics waste separation, presents an innovative principle for plastics flotation, and provides various methods for the separation of plastics mixtures. The objective is to understand the mechanisms for selective flotation separation of plastics, get plastics mixtures separated and enable more plastics wastes to be recycled. READ MORE
