Compounding extruders: what are they? What is its use in the recycling process?

In the process of plastic waste recycling, the compounding extruder is typically used to combine and process recycled plastic material with additives or other materials to produce a final product with specific desired properties.

The compound extrusion machine is similar to a mixing extruder in that it consists of a long, heated barrel with a rotating screw inside. The screw conveys, melts, and mixes the plastic waste material as it moves through the barrel. However, the compounding extruder is typically designed to handle a wider range of materials and operate at higher pressures and temperatures than a mixing extruder. This allows it to effectively melt and mix even highly resistant or non-homogeneous plastic waste materials.

After the plastic waste and any additives or other materials have been processed through the compounding extruder, the resulting compound is typically pelletized or otherwise formed into a uniform shape for further processing or reuse.

Overall, the compounding extruder line plays a vital role in combining and processing recycled plastic material with additives or other materials to produce a final product with specific desired properties.
