  2. 1. Cone Crusher Performance

    Author : Magnus Evertsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mining; size-reduction; particle size; crushing; comminution; modelling; simulation; aggregates;

    Abstract : Cone crushers are used by both the aggregate producing and the mining industry. Both industries are interested in increasing the product quality while at the same time lowering the production costs. Prediction of crusher performance has been focused on, since crushing is a vital process for both industries. READ MORE

  4. 2. Load-Haul-Dump operations in underground mines

    Author : Bartlomiej Skawina; Jenny Greberg; Abubkary Salama; Oliver Langefeld; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LHD; DES; simulation; underground mine; energy consumption; ventilation requirements; orepass loss; production scheduling; process control; Mining and Rock Engineering; Gruv- och berganläggningsteknik;

    Abstract : The research presented in this thesis addresses several aspects of loading operations inunderground mines, in particular tools and equipment selection. It also addresses the flexibilityof the fleet when subject to substantial disturbances, such as ore pass loss, and proposes integration of the scheduling system with discrete event simulation.

  5. 3. On the Improvement of Healthcare Management Using Simulation and Optimisation

    Author : Marie Persson; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Simulation; Optimization; Management; Healthcare;

    Abstract : This thesis concerns healthcare management and specifically addresses the problems of operating room planning and waiting list management. The operating room department is one of the most expensive areas within the healthcare system which necessitates many expensive resources such as staff, equipment and medicine. READ MORE

  6. 4. 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.

  7. 5. A dispatch procedure for traffic control of a fleet of remote-controlled automatic LHDS in underground hard rock mines : modelling approach is based on simulation

    Author : Nikolaos Vagenas; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mining and Rock Engineering; Gruv- och Berganläggningsteknik;

    Abstract : A concept for automating Load-Haul-Dump (LHD) vehicles has stimulated considerable interest in the Swedish mining industry. In this concept, tramming and dumping operations of an LHD should be automatic. During loading, an operator from a control room fills the bucket of a vehicle via remote-control aided by a television system. READ MORE
