A flow visualisation apparatus is described which allows to compare different rotor designs to each other. In order to observe the distributive mixing effect, the stream flow and dispersive mixing effect is monitored by an indirect measurement of the power impact within the material. Assuming that the mixing process of an internal mixer is not continuous, a testing device was build to the scale of a 90 l kneader. In this device the mixing chamber and the rotor blade are unwound into the flat plane. With this testing device it is possible to carry out a systematic analysis of the influence of rotor design on the flow processes within an internal mixer in a fast and inexpensive way.The test device.
