Abstract
We have developed a non-contact measuring method of mixing process in the mixer using a micro focus X-ray computer tomography. And its effectiveness was demonstrated from the experimental observation of mixing process of two kinds of particle with different X-ray transmission. The cross sectional image of particle packed bed in the cylindrical container rotation type mixer was obtained from the X-ray transmission images, and the image analysis of these cross sections was performed. From the brightness of each particle image, the particle materials can be detected and obtains the ratio of each particle on every section.
The degree of mixing was calculated from the measured distribution of each particle, and the effect of the separation plate in the mixer on the mixing performance of a cylindrical container rotation type mixer was studied. The actual mixing state in the mixer can be measured by non-contact, and the mixing degree in the mixing process from cross-sectional image analysis can estimate directly was shown.
