21. Mechanical Characterization of Heterogeneous Brittle Materials
Sammanfattning : Comminution is one of the highest energy-consuming processes in the mining and mineral processing industry by consuming around 2% of the global generated energy with an overall efficiency of 1-3%. Different approaches to the optimization of processes have been developed, but there is still room for improvement. LÄS MER
22. The mechanisms controlling heat and mass transfer on frying of beefburgers
Sammanfattning : The aim of the present work was to gain better understanding of the mechanisms controlling heat and mass transfer during thermal processing of beefburgers. The effects of different factors such as the chemical composition and comminution of the meat raw material, the pan temperature and the meat patty diameter on the characteristics of heat and mass transfer were studied.

23. Mechanical activation of hematite using different grinding methods with special focus on structural changes and reactivity
Sammanfattning : The mechanical treatment of solids is one of the most common and widely used operations which man has been concerned from the very beginning of the history of civilization. Nowadays, mechanical activation has a wide range of application potentials. LÄS MER
24. 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
25. Particle generation for geometallurgical process modeling
Sammanfattning : A geometallurgical model is the combination of a spatial model representing an ore deposit and a process model representing the comminution and concentration steps in beneficiation. The process model itself usually consists of several unit models. LÄS MER
