  2. 1. 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.

    Abstract : Biological cells appear everywhere on earth. They might live on their own as unicellular organism, like bacteria, or might form complex organisms consisting of several thousands or millions of cells. Despite their small size of only a few micrometers, they are complex little miracles. READ MORE

  6. 4. Accelerated granular matter simulation

    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; discrete element method; nonsmooth contact dynamics; multibody dynamics; granular media; simulation; projected Gauss-Seidel; validation; iron ore pellets; pelletising balling circuit; model reduction; design optimization;

    Abstract : Modeling and simulation of granular matter has important applications in both natural science and industry. One widely used method is the discrete element method (DEM). It can be used for simulating granular matter in the gaseous, liquid as well as solid regime whereas alternative methods are in general applicable to only one. READ MORE

  7. 5. DEM Modelling of Vibratory Screens

    Author : Ali Davoodi; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Validation; Modelling; Screen efficiency; DEM simulation;

    Abstract : In Sweden, about 100 million tons of aggregate is used for road, railway, and concrete every year. Crushing is the main process for producing aggregate material in different fractions. The production process is divided into two sub-processes: comminution or size reduction and classification. READ MORE
