Single Screw Extruder and Recycling Pelletizing System for Pet

The ACS series compacting and pelletizing system integrates the functions of crushing, compacting, plasticization, and pelletizing into one step, making it ideal for plastics recycling and pelletizing processes. This system is a reliable and efficient solution for re-pelletizing PP, PE, PET, PVC films, raffias, filaments, PP woven/non-woven bags, and EPE/EPS/XPS foaming materials.

The final products from the ACS system are in the form of pellets or granules, which can be directly fed into production lines for film blowing, pipe extrusion, and plastic injection, among other applications.

Working Steps of ACS Compacting and Pelletizing System


1. Feeding: As standard, plastic scraps like films, filaments, and raffias are conveyed into the compacting chamber via belt conveyor. For roll scrap, an optional roll hauling off device is available. The motor drives of the conveyor belt and hauler work with ABB inverters, allowing fully automatic feeding based on how full the compactor is. A metal detector can be integrated with the conveyor to stop the system if any metal is detected.

2. Crushing and Compacting: The rotating blades in the compactor cut the incoming scraps. Frictional heating from high-speed rotation helps shrink the material just below its agglomeration point. An optimized guide structure compacts the material and directs it into the extruder screw. This process effectively crushes, dries, and compacts the material for stable feeding into the extruder.

3. Sliding Gate: Installed between the compactor outlet and the extruder inlet, this gate controls the time the material spends in the compactor and adjusts the feeding capacity of the compacted material.

4. Plasticization and Degassing: A specialized single-screw extruder gently melts the pre-compacted material. The plastic scraps are well melted and plasticized in a 32–34D processing section. With a double-zone vacuum degassing system combined with a root pump unit, the vacuum pressure can reach up to -0.1MPa, ensuring maximum removal of volatiles from PET melts and minimizing IV value reduction.

5. Melt Filtration: A standard pillar-type screen changer is installed at the head of the extruder, offering significant filtration performance. The filter requirements depend heavily on the quality of the input material and the intended use of the granules.

6. Pelletizing: The strand pelletizing unit is commonly used for PET. The strands coming out of the extruder die are manually guided into a water trough for cooling, then dried using an air knife before being cut by the rotary blades of the pelletizer into granules or chips.
