3. 2. Process-induced disorder of pharmaceutical materials : Mechanisms and quantification of disorder

   Författare :Samaneh Pazesh; Göran Alderborn; Jonas Berggren; Niklas Sandler; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Milling; Comminution; Powder flow; Amorphisation; Raman spectroscopy; Atomic force microscopy; Plastic stiffness; Elastic stiffness; Pharmaceutical Science; Farmaceutisk vetenskap;

   Sammanfattning : One of the most important prerequisites in the drug development is to attain a reproducible and robust product in terms of its nature, and its chemical and physical properties. This can be challenging, since the crystalline form of drugs and excipients can be directly transformed into the amorphous one during normal pharmaceutical processing, referred to as process-induced amorphisation or process-induced disorder.

4. 3. Applications of Dynamic Modeling in Crushing Plants

   Författare :Marcus Johansson; Chalmers tekniska högskola; []
   Nyckelord :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;

   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. 4. Efficient modeling and control of crushing processes in minerals processing

   Författare :Marcus Johansson; Chalmers tekniska högskola; []
   Nyckelord :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;

   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

7. 5. Particle generation for geometallurgical process modeling

   Författare :Pierre-Henri Koch; Jan Rosenkranz; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Geometallurgy; ore texture; texture classification; breakage simulation; process modeling; Mineralteknik; Mineral Processing;

   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
