Working Steps of ACSS Compacting and Pelletizing System
1. Feeding: As standard, plastic scraps such as film, filament, and raffia are conveyed into the compacting room via a belt conveyor. For roll scraps, an optional roll hauling off device is available. Motor drives for the conveyor belt and hauling device work with ABB inverters to automatically adjust feeding speed based on the compactor's fill level. A metal detector can be integrated with the conveyor belt to stop the system if metal is detected during feeding.
2. Crushing and Compacting: The rotating blades of the compactor cut the incoming scraps. Frictional heating from the high-speed blades 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 crushes, dries, and compacts the material for fast and stable feeding into the extruder.
3. Plasticization and Degassing: A specialized single screw extruder gently melts the pre-compacted material. The first stage extruder melts and plasticizes the material, while the second stage extruder extrudes it. With a double-zone vacuum degassing system, volatile substances like low molecular compounds and moisture are efficiently removed, making this system especially suitable for heavily printed films and materials with some moisture content.
4. Melt Filtration: The filtration principle involves coarse filtering in the first extruder and fine filtering in the second extruder, reducing the frequency of sieve changes. The filter technology requirements depend heavily on the quality of the input material and the intended use of the granules.
5. Pelletizing: The standard granulating method in the ACSS system is the die-face water ring pelletizing system. A self-adjusting pelletizing head ensures the best 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. An advanced dewatering vibration sieve combined with horizontal centrifugal dewatering provides high-performance dried pellets.
