Air Cooling Hot Face Cutter for Plastic Recycling
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 offers a reliable and efficient solution for re-pelletizing materials such as plastic films, raffias, filaments, bags, woven bags, and foaming materials.
The final products produced by 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 Series Compacting and Pelletizing System:
1. **Feeding**: As a standard design, plastic scraps like film, filament, and raffia are conveyed into the compacting chamber via a belt conveyor. For handling roll scraps, a roll hauling off device is an optional feeding method. The motor drives of the conveyor belt and hauling device work with ABB inverters. The feeding speed is fully automatic based on the compactor's fill level. A metal detector can be integrated with the belt conveyor to interlock with the control system, warning and stopping the system if metal is detected in the feed section.
2. **Crushing and Compacting**: The rotating blades of the compactor cut the incoming scraps. Frictional heating caused by high-speed rotation heats the scraps just below their agglomeration point. An optimally designed 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 from the compactor into the extruder.
3. **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, volatiles such as low molecular compounds and moisture are efficiently removed, especially suitable for heavy printed films and materials with some moisture content.
4. **Melt Filtration**: A regular single-plate/piston double-station screen changer or a non-stop double-plate/piston four-station can be installed on the extruder head to provide significant filtration performance. The requirements for filtration technology depend heavily on the quality of the input material and the planned use of the granules.
5. **Pelletizing**: The die-face water ring pelletizing system is set as the standard granulating method in the ACS system. The self-adjusting pelletizing head ensures optimal granulate quality and long uptime due to consistent blade pressure. The RPM of the rotating blades is automatically adjusted based on the melt extruding pressure. Additional systems such as strands pelletizing, under-water pelletizing, and hot face pelletizing are available for different materials. Advanced dewatering vibration sieve combined with horizontal-type centrifugal dewatering ensures high-performance dried pellets.
