How It Works :
①Side force feeder ➜ ②1^st Plastic extruder ➜ ③2^nd Plastic extruder ➜ ④Water ring pelletizing system ➜ ⑤Centrifugal dryer ➜ ⑥Vibrating screening unit ➜ ⑦Automatic big bag filling system

Side force feeder is to feed crushed plastic films into plastic extruder. Since the recycled plastics are dirty, the melts must be processed twice by extruder to maintain quality. By repeating process of melting, kneading, and filtering, it ensures impurities of the melts are removed during extrusion. The melts then pass through water ring pelletizing system to be cut into pellets. The pellets are cooled, dried, and screened to become reusable resources.

• Side force feeder
  

  The crushed plastic films are fed into plastic extruder via side force feeder. The equipment can effectively increase feeding capacity of films.



• Extruder screw
  

  Extruder screw is the heart of the plastic extruder. The screw design, material, and machining accuracy are going to determine production efficiency and material quality.



• Water ring pelletizing system
  

  Water ring pelletizing system is widely used, but it is not suitable for sticky, low-viscosity materials because pellets can stick together before they hit the water. When the molten polymer exits the die holes and is cut into pellets by rotating knives in air. The pellets produced outwards are cooled by water and then transported to downstream centrifugal dryer.



• Centrifugal dryer
  

  The equipment is to eliminate surface moisture on pellets. It is located after pelletizing machine.



• Vibrating screening unit
  

  The unit can screen out different sizes of plastic pellet to ensure a good average quality of the materials.



• Automatic big bag filling system
  

  The system enables efficient filling of bulk bags with automatic system. It is stable and easy for operation. It’s an ideal equipment for large-size packaging of materials.
