1. Theoretical Optimization of Compressive Crushing
Sammanfattning : 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. LÄS MER
2. DEM Modelling and Simulation of Cone Crushers and High Pressure Grinding Rolls
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.

3. Mehanics of Rock Fragmentation Static and Dynamic Laboratory Testing Applied to Aggregate Production
Sammanfattning : 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. LÄS MER
4. Applications of Dynamic Modeling in Crushing Plants
Sammanfattning : 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. LÄS MER
5. Efficient modeling and control of crushing processes in 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
