WPC (PE+Wood) Parallel Twin-screw Pelletizing Line(Crushing Process)

Q1: What is the main application of this pelletizing line?

A1: This line is mainly used for producing WPC (Wood Plastic Composite) pellets by combining waste PE plastic with wood powder, rice husk, or other natural fibers. The produced pellets are suitable for WPC decking, wall panels, and other extrusion products.

Q2: How is temperature controlled during processing?

A2: The line uses precise multi-zone temperature control systems to ensure stable plasticization and prevent degradation of wood powder and polymers.

Q3: What does the “Crushing Process” mean in this pelletizing line?

A3: In this system, the “crushing process” refers to the post-pelletizing cooling stage. After the pellets are discharged from the extruder, they are crushed and separated by an air-blowing fan, which helps to quickly cool down the hot pellets. This method effectively reduces pellet sticking, shortens cooling time, and significantly increases production efficiency.

Q4: What is the advantage of using the crushing cooling system instead of traditional water-cooling?

A4: The air-blowing and crushing cooling system avoids water contact, keeping pellets dry and clean. It also reduces the need for drying, saves energy, and is especially suitable for WPC materials that absorb moisture easily.

Q5: Does the crushing process affect pellet quality?

A5: No. The crushing and cooling system is precisely designed to maintain uniform pellet size and prevent deformation while achieving rapid cooling.

Q6: How does this system help increase output?

A6: By cooling the pellets faster and continuously, the line can run at a higher extrusion speed without overheating or blocking, thus improving output capacity and ensuring stable, continuous production.
