Abstract

Positron emission particle tracking with positron annihilation spectroscopy was used in order to visualize particulate motion within a high shear mixer. As a result, it was possible to visualize the high-speed behavior of particulates within a fluid bed in a mixer, which is an important basic operation in materials processing. It was demonstrated that this method can be useful in improving process design or in improving the quality of the resultant product.
