The Definition of Conveying Screw Element

Conveying screw elements, or segments, are integral components within the extruder’s barrel. They are responsible for conveying the raw materials from the feed hopper to the die, ensuring proper mixing, melting, and shaping of the material. Conveying screw elements have become the preferred choice for extruder screw components due to their excellent material transport capabilities, brief material residence duration, and effective self-cleaning characteristics.

SKR Machinery offers a range of standard conveying screw elements that are compatible with numerous international extruder brands, including Coperion, Leistritz, Berstorff, Toshiba, JSW, Kobe, APV, Maris, and more.
