Effect of the Intensive Plasticizing Zone Design on the Effectiveness of Corotating Twin-Screw Extrusion

Figure 2

Configuration of the screws. SK represents single-flight transporting segments; SE represents double-flight transporting segments. The first number is the flight pitch, the second is the length of a segment, and KBW represents the kneading segments with double-lobe cams (disks). The first number is the angle between the cams’ axes of symmetry, the second one is the width of cam elements, and the third is the length of a segment; the letter denotes the inclination of the apparent screw line of cam elements (Li: left; no letter: right).
