500Kg/H Capacity Plastic PE Film water ring Granulation Production Line With

Product Specification

Overview of the Plastic Recycling and Granulation Production Line:
A1. Waste plastic films or bags that have undergone cleaning and recovery processes can be processed by this equipment into plastic granules. After undergoing blow molding or injection molding processes, these recycled granules can be utilized to manufacture brand-new plastic products—such as plastic films, bags, bottles, pallets, turnover boxes, drums, and more.
A2. This equipment is suitable for processing a wide variety of plastic raw materials, including PE, PP, HDPE, LDPE, and LLDPE.
A3. We offer two configuration options: a single-stage system or a double-stage system (also known as a "master-slave" machine structure).
A4. The entire production line is operated and managed via a touch-screen control system.

Layout of the PE/PP Film and Woven Bag Scrap Extrusion and Granulation Production Line:
1. Conveyor Belt → 2. Semi-automatic Metal Detector → 3. Compacting Force Feeder → 4. First-stage Extruder → 5. Screenless Hydraulic Screen Changer (Compared to a standard hydraulic screen changer, this device can increase throughput by approximately 10%, though its overall cost is higher; therefore, we typically recommend using a standard hydraulic screen changer) → 6. Second-stage Extruder → 7. Standard Hydraulic Screen Changer → 8. Die-face Hot Cutting System → 9. Water Cooling Tank → 10. Centrifugal Dewatering Machine → 11. Vibrating Screen Separator → 12. Pneumatic Conveying System and Storage Silo

The compacting and feeding section of this granulation line is specifically designed for the recycling and processing of PP/PE films and woven bags. The system incorporates fully automatic water-ring pelletizing technology, producing plastic granules that are plump, spherical in shape, and free from clumping or adhesion. The pelletizing cutter head typically features a three-blade configuration, ensuring exceptionally high cutting efficiency; furthermore, the blades maintain perfect contact with the die face, resulting in clean cuts and uniform, consistent granules.

The screen changer serves as a core component in this granulation line, playing a critical role in ensuring process stability and the consistent quality of the resulting granules. Its primary function is to continuously filter and remove various contaminants—such as carbonized particles and gel spots—from the polymer melt. By trapping these impurities, the screen changer not only effectively protects downstream equipment from wear and tear but also serves as a fundamental safeguard for the production of high-quality, defect-free plastic pellets. This filtration process is achieved by forcing the melt to flow through a fine-mesh screen. Should the screen become clogged—resulting in an increase in melt pressure—the system automatically triggers an alarm to alert operators to perform a manual screen change. This mechanism ensures both the continuity of the production process and the stability of the melt pressure, thereby laying a solid foundation for achieving superior product quality.

To accommodate different types of raw materials and varying requirements regarding the shape and characteristics of the final pellets, customers can flexibly choose between two distinct pelletizing methods: "water-ring pelletizing" or "strand pelletizing." This flexibility offers a wider range of options concerning both the visual morphology of the pellets and the cooling process employed. The production line is equipped with robust drive units and advanced control systems supplied by industry-leading vendors—such as Internationally renowned brand and ABB—ensuring stable operation, ease of maintenance, and reliable long-term performance.
