Mixing behaviour

→ To the calculation bases

• Transverse mixing ratio, longitudinal mixing ratio and agglomerate comminution: These 3 values are calculated for each process and are also mentioned in the short_report. The values are calculated purely analytically and are displayed in the upper part of the window as a ‘mixture triangle’.
• Disperse, distributive and thermal mixing index: In the lower section of the window, the mixing ratios for the supported zone types (cross-hole mixing, diamond mixing, spiral shear elements, metering zones) are displayed in the melt area of the extruder. The disperse and distributive mixing quality is calculated for all zones. The thermal homogeneity is also calculated for cross-hole mixing parts.

• The analytically calculated key figures provide a quick overview of the mixing behaviour of the extruder. A value of 0 corresponds to a good mixing effect, a value of 1 to a poor mixing effect. The smaller the ‘mixing triangle’, the better the mixing effect of the screw. It should be noted here that the mixing behaviour in the extruder is based on complex flows and that this can only be described with limited accuracy by a purely analytical approach.
• The numerical mixing parameters offer a more precise assessment of the mixing quality. A value of 1 corresponds to an optimal mixing effect and a value of 0 to a poor mixing effect. The values are primarily used to optimise the geometry of the respective screw zones to achieve a good mixing effect.
