Abstract
The flow pattern and the mixing process of powder in the vertical-cylinder-type mixer were investigated using photographic observation and measurements of the concentration profile of a tracer. Furthermore, using white glass particles as a tracer, the flow pattern in the mixer was studied by the model mixer, in which glass beads were made transparent by methylbenzoate, having same refractive index with glass beads.The flows of powder varied according to the local position in the mixer. Those characteristics were shown in term of the local rate coefficient of mixing.Desirable mixing states were observed under the condition of strong shear force and large rectangular velocity gradient in powder at the front edge of the paddle. In addition, many flowing circuits and mixing zones were found at the other regions.
