The finished high-quality recycled granules can be directly used for secondary production such as injection molding, blow molding and extrusion molding, applied in packaging, building materials, daily plastic products and other industries to realize efficient waste resource utilization.

Working Process

1. Raw Material Pretreatment: Crush, clean and dehydrate waste plastics, scraps and runner materials to remove sediment, oil stains and impurities to guarantee raw material cleanliness.
2. Constant Feeding: 22KW motor matched with thickened hard-tooth surface feeding reducer sends pretreated raw materials into the barrel stably and constantly to avoid material blockage and shortage.
3. Segmented Plasticization: Realize gradual melting of plastic raw materials via main machine electromagnetic heating and secondary machine heating ring zoned precise temperature control to ensure thorough and uniform plasticization.
4. Filtration and Extrusion: The screw extrudes melt at high speed, and high-precision impurity filtration is completed via hydraulic screen-changing head with screen changing available without shutdown for continuous discharging.
5. Cooling and Pelletizing: Extruded strip-shaped plastic melt is shaped via water cooling and air cooling, then cut into uniform granules by pelletizer.
6. Screening and Discharging: Classify finished granules, put qualified granules into warehouse, and reprocess impurity waste materials in the machine.
