The ACS series compacting and pelletizing system integrates 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 film, filament, and raffias are conveyed into the compactor chamber via belt conveyor. For roll scraps, a roll hauling off device is an optional feeding method. Motor drives of the conveyor and hauling device work with ABB inverters. The feeding speed is fully automatic based on how full the compactor is. A metal detector can be combined with the conveyor and interlock with the control system to stop the machine if metal is detected.
2. Crushing and Compacting: The rotating blades of the compactor cut the incoming scraps. Frictional heating from high-speed rotation heats the scraps just below their agglomeration point. An optimized guide structure compacts the material and directs it into the extruder screw. This process crushes, dries, and compacts the material, enabling fast and stable feeding into the extruder.
3. Sliding Gate: Installed between the compactor outlet and the extruder barrel inlet, this gate controls the time the material spends in the compactor and adjusts the feeding capacity.
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 to 34D processing section. With a double-zone vacuum degassing system combined with a roots pump unit, the vacuum pressure can reach -0.1MPa, effectively removing volatiles from PET melts to ensure minimal IV value reduction.
5. Melt Filtration: A pillar-type screen changer is installed on the extruder head for effective filtration. The filter technology requirements depend heavily on the input material quality and the planned use of the granules.
6. Pelletizing: The strands pelletizing unit is the typical method for PET. The strands from the extruder die are manually hauled into a water trough for cooling, then dried using an air knife device, cut by the rotary blades of the pelletizer, and formed into granules/chips.
