Water Ring Pelletizer for PP and PE Plastic Film/Woven Bags

The picture presents a comprehensive industrial setup dedicated to plastic recycling and processing. It showcases a series of interconnected machines and equipment, forming a complete production line to handle, treat, and transform plastic waste into reusable pellets or granules. Key Observations: Multiple Stages: The facility is organized into distinct stages, each with specialized equipment, suggesting a multi-step recycling and processing approach. Conveyor Systems: A network of conveyor belts, both horizontal and inclined, transports plastic materials between different processing stages. Variety of Machines: The line includes diverse machines, indicating various treatment processes such as shredding, washing, drying, extruding, and pelletizing. Extrusion Line: The central component is an extrusion line, consisting of an extruder and a pelletizer. The extruder melts and homogenizes the plastic material, while the pelletizer cuts the extruded plastic into uniform pellets. Feeding and Storage: Hoppers, silos, and large bags are present for feeding materials into the system and storing processed plastic pellets. Control Systems: Control panels and automation equipment are visible, indicating precise control and monitoring of the process parameters. Potential Processing Steps: Pre-processing (Not Fully Visible): This stage may involve sorting, shredding, and washing the plastic waste to remove contaminants and prepare it for further processing. Extrusion: The cleaned plastic flakes or granules are fed into the extruder, where they are melted and homogenized under controlled temperature and pressure. Filtration (Possible): A filtration system might be present to remove any remaining impurities from the molten plastic. Pelletizing: The molten plastic is then extruded through a die and cut into uniform pellets by the pelletizer. Cooling and Drying: The pellets are cooled and dried to ensure their stability and quality. Storage and Packaging: The finished plastic pellets are stored in silos, bags, or other containers for transportation or further processing. Applications and Benefits: Circular Economy: The facility contributes to a circular economy by converting plastic waste into reusable material, reducing reliance on virgin plastics and minimizing environmental impact. Resource Recovery: It recovers valuable resources from discarded plastics, preventing them from ending up in landfills or polluting the environment. Sustainable Manufacturing: The recycled plastic pellets can be used to manufacture various new products, promoting sustainable practices in multiple industries. Economic Advantages: Plastic recycling can offer economic benefits by reducing waste disposal costs and creating value from discarded materials. Overall, the picture portrays a sophisticated and efficient plastic recycling and processing facility that plays a significant role in promoting sustainability, resource conservation, and responsible waste management.


The recycling of PP and PE plastic films and woven bags has always been a complex process, requiring multiple steps and machines. The Water Ring Pelletizer for Clean PP and PE Plastic Film/Woven Bags is an advanced solution that streamlines this process by combining crushing, compacting, plasticization, and pelletizing into a single stage. This results in high-quality pellets that can be directly used in various production lines, enhancing your bottom line.

Working Principle

  1. Feeding: The machine employs a belt conveyor to feed plastic scraps like films and raffias into the compacting room. For roll scraps, an optional roll hauling off device is available. The feeding speed adjusts automatically based on the compactor’s room capacity. A metal detector can also be integrated to halt the system if metal is detected.
  2. Shredding and Compacting: Rotatory blades in the compactor cut up the incoming scraps, generating frictional heat that shrinks the material just below their agglomerating point. This optimally designed guide structure directs the material into the extruder screw, enabling fast and stable feeding.
  3. Plasticization and Degassing: A specialized single screw extruder gently melts the pre-compacted material. A double-zone vacuum degassing system efficiently removes volatiles, making it especially suitable for heavy printed film and moist materials.
  4. Melt Filtration: The machine employs a segmented filtering principle to reduce the frequency of filter sieve changes, ensuring a smoother operation.
  5. Water-ring Pelletizing: This is the standard granulating method used, coupled with an advanced dewatering vibration sieve and horizontal-type centrifugal dewatering for high-performance dried pellets.
