Planetary roller extruders (PREs) are currently being employed first and foremost to feed calender/lamination units, for pelleting, for compounding powdered paint and for the reuse of recyclate. In these disciplines it is the most successful multi‐screw extruder. The range of materials that are compounded extends from classical plasticised poly(vinyl chloride) (PVC), via poly(propylene) (PP) and acrylonitrile‐butadiene‐styrene (ABS), through to powdered rubber. The planetary roller extruders convince in comparison with other compounding machines through the thermally carefully compounding, the balanced ratio of shear and heat transfer and the narrow residence time distribution. Experimental investigations to analyze the process behavior of PREs were carried out for the first time.Homogenization and dispersion at a material‐bank in the planetary roller extrusion test stand.
