  2. 1. Theoretical Optimization of Compressive Crushing

    Author : Elisabeth Lee; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Consumption; Fitness Function; Genetic Evolutionary Algorithms; Crushing Pressure; Optimization; Product Yield; Compressive Crushing;

    Abstract : Surrounded by products made from crushed rock materials in all corners of society, most people do not spend much time thinking about when, where, or how these are produced. In fact, most people take the supply and availability of products made from crushed rock materials for granted. READ MORE

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

    Author : Johannes Quist; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. 3. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production

    Author : Bahman Bohloli; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; anisotropy; aggregates; rock failure; saturation; Brazilian test; dynamic tensile strength; Hopkinson pressure bar; fragmentation; rock fines; crushing;

    Abstract : Knowing the strength properties of rocks is essential for calculating the stability of natural slopes, constructions in and on rock, excavations, blasting geometry, crushing, and drilling. When rock and rock masses are subjected to either dynamic or static loads, the tensile strength is determined by tests appropriate to the load type. READ MORE

  6. 4. Applications of Dynamic Modeling in Crushing Plants

    Author : Marcus Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Comminution; Plant design; Jaw crusher; Dynamic modeling; Robustness; HPGR; Minerals processing; Material storage; Calibration; Process control;

    Abstract : Modeling is a tool to describe phenomena in a simplified way, and the models can then be used to simulate these phenomena. Models of equipment used in the mining and aggregate industries can be used for process simulations of the processes in those industries to improve the operations. READ MORE

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

    Author : Marcus Johansson; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE
