Side Feeder for Twin-Screw Extrusion Lines
A side feeder is used to introduce fillers, additives, reinforcing materials, and other secondary ingredients into a selected downstream section of the twin-screw extruder. This allows the main polymer to melt first before additional materials enter the process.
For compounding lines, the side feeder must be matched with the extruder, screw configuration, feeding position, and material characteristics. Nanjing Hundred Horse configures the side-feeding system according to the production requirement, filler ratio, material flowability, and target output.
Side feeders are commonly used for mineral fillers, glass fiber, flame-retardant additives, powders, and high-filler masterbatch formulations. Correct side-feeding design helps improve material incorporation, reduce feeding instability, and support continuous production.
The final configuration depends on the compound recipe, barrel layout, venting arrangement, and pelletizing method.
