Analysis and optimization of particle grinding in a spiral air jet mill


Particle size reduction is a highly energy intensive operation and even small improvements in efficiency can result in significant energy savings. The focus of the present work is analysis and optimization of an air jet mill, which is a versatile equipment used in many industries for fine grinding of powders to sizes less than around 10 microns. The objective of the project is be to develop a detailed simulation model using computational fluid dynamics (CFD) and the discrete element method (DEM).
