Dvigubas sraigtinis ekstruderis pasižymi priverstinio transportavimo savybėmis, trumpu buvimo laiku, geru išmetamųjų dujų našumu, tolygiu maišymu ir maža galia. Dvigubas sraigtinis ekstruderis daugiausia susideda iš dviejų tarpusavyje sujungtų varžtų, besisukančių cilindre, priverčiančių medžiagą kirpti ir judėti į priekį.
Žemiau pateikiama skaitiklio su dviem varžtais ekstruderio veikimo principo analizė:
Du varžtai sukasi priešinga kryptimi, kai yra du atvejai: vidinis ir išorinis. Sukimosi į vidų situacija yra palyginti maža, kai dviejų varžtų ekstruderis sujungiamas priešinga kryptimi. Tai daugiausia dėl to apie, if the thread apie the feeding section is not fully meshed and not fully closed in the longitudinal and horizontal direction, the material is easy to form a pile between the radial clearance apie the two screws and above the two screws, thus reducing the free space apie the screw groove, and finally affecting the ability apie the screw to accept the material from the feeder, not only affects the feeding performance apie the screw groove, but also forms a bridge. Secondly, the material with radial clearance apie two screws is rotated inward, and the reaction force will press the two screws towards the cylinder wall on both sides, which will accelerate the wear apie screw and barrel. In the same way, the two screws apie non meshing and non engaging two-screw extruder are inward rotating.
From the appearance, the thread direction apie the two opposite rotating screws is opposite, one is left-handed, the other is right-handed, but they are symmetrical. When the material falls on the screw, it will quickly separate to both sides, fill the screw groove, transport forward, and quickly contact with the heat cylinder to absorb heat, which helps to heat and melt the material.
