Abstract
Various measures increase the cooling effect on a planetary roller extruder section/module. Those measures include a choke being arranged at an outlet of the planetary roller extruder section or module, a distance between centerlines of adjacent planetary spindles being at least equal to an outer diameter of the planetary spindles, providing a pressurized melt supply, having a cooling section composed of several sections/modules, providing at least one section/module in which a flow, during melt supply is converse to the conveying direction of the extruder, and providing cooling tubes arranged within the central spindle.
