  2. 2. Vibration signal analysis in comminution

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Yigen Zeng; [1994]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Processing; Mineralteknik;

    Sammanfattning : Comminution accounts for a significant part of the energy consumption and metal wear in powder manufacturing industries and as a result, it is a major cost factor. To maintain high efficiency, the operating parameters must be monitored and adjusted promptly to optimal values. LÄS MER

  3. 3. Distal Radius Fractures aspects on radiological and clinical outcome and evaluation of a new classification system

    Detta är en avhandling från Umeå : Umeå universitet

    Författare :Mats Wadsten; Umeå universitet.; [2016]
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Distal radius fracture; Buttazzoni classification; volar; comminution; reliability; radiological outcome; clinical outcome; late displacement; ortopedi; Orthopaedics;

    Sammanfattning : Distal radius fracture (DRF) is the most common fracture encountered in clinical practice. Every year, more than 20000 people in Sweden suffer from this injury. It has been shown that there is a correlation between malalignment and function following distal radial fractures and malunion may cause persistent pain and disability. LÄS MER

  4. 4. DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Johannes Quist; [2017]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete Element Method; Modelling; HPGR; Comminution; DEM; Simulation; Crushing; Minerals Processing; Cone Crusher;

    Sammanfattning : The comminution of rock and ore materials consumes ~1.5-1.8 % of the total energy production in mining intensive countries (Tromans, 2008). Several research findings show that there are ways of utilizing compressive breakage modes that are more energy efficient compared to conventional grinding circuits based on large inefficient tumbling mills.

  5. 5. Efficient modeling and control of crushing processes in minerals processing

    Detta är en avhandling från Gothenburg : Chalmers tekniska högskola

    Författare :Marcus Johansson; [2019]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HPGR; Comminution; Jaw crusher; Process control; Modeling; Dynamic modeling; Minerals processing;

    Sammanfattning : Modeling and simulation is a tool to explore and increase the understanding of a phenomenon. This thesis focuses on developing models of crushers and equipment used in the mining industry. Specifically, the focus is on a branch of modeling called time dynamic modeling which is a model that gives an output as a function of time. LÄS MER
