Mechanisms of Fragmentation in Ultrasound Assisted Impact Comminution
Abstract. Impact fragmentation is the underlying principle of comminution milling of dry, bulk solids. Unfortunately the outcome of the fragmentation process is more or less determined by the dimensionality of the impactor and it’s impact velocity, prohibiting the adjustment of desired fragment distributions. By modifying target shapes or impact angles, differences in the fragment mass distribu...
متن کاملOptimisation of Fragmentation and Comminution at Boliden Mineral, Aitik Operation
The objective of this thesis is to optimise the fragmentation at Boliden Minerals open pit mine Aitik. Blasting is one of the main operations in mining, and its performance has a major impact on the overall economy of the mine. The fragmentation process affects not only the local productivity and unit costs of the mining department. It also affects the performance of the subsequent comminution ...
متن کاملUltrasound-Assisted Biodiesel Production in microreactors
The ultrasound-assisted (UA) soybean oil methanolysis using KOH as a catalyst was studied at different reaction conditions in a microreactor. Box–Behnken experimental design, with three variables, was performed and the effects of three reaction variables i.e. reaction temperature, catalyst concentration and the methanol-to-oil molar ratio on fatty acid methyl ester (FAME) yield were evaluated b...
متن کاملUltrasound assisted particle and cell manipulation on-chip.
Ultrasonic fields are able to exert forces on cells and other micron-scale particles, including microbubbles. The technology is compatible with existing lab-on-chip techniques and is complementary to many alternative manipulation approaches due to its ability to handle many cells simultaneously over extended length scales. This paper provides an overview of the physical principles underlying ul...
متن کاملSheared granular layers: Competition between flash heating and particle comminution
Quantitatively predicting the dynamic response and energy partition of granular fault gouges under shear remains a major challenge in seismology. Earthquake laboratory experiments are limited by capacity of equipments and thus cannot provide similar conditions in real earthquake ruptures. This motivates the development of computational models of granular fault gouge that accurately predict thei...
