PE Pelletizing Machine

Parallel twin screw PE pelletizing machine is the core equipment for recycling and processing of PE plastics. It converts PE recycling pellets, wood powder, CACO3 and some additives into reusable granular raw materials through physical processing and is widely used in various links of the plastic industry chain, especially PE-based wpc decking floor production.

Parallel twin screw pe pelletizing machine has the following characteristics:

1. Targeted WPC Decking Material Processing
PE pelletizing machine, Specialized parallel twin-screw structure, perfectly tailored for compounding PE (including recycled PE) with wood powder, calcium carbonate and other additives, producing uniform pellets that meet the strict raw material requirements of WPC decking extrusion.

2. High Mixing & Homogenization Performance
The tapered screw design of this PE pelletizing machine creates strong shearing and kneading force, ensuring full dispersion of wood fiber in the PE matrix; avoids fiber agglomeration and material stratification, thus enhancing the mechanical strength and weather resistance of the final WPC decking products.

3. High Efficiency & Low Energy Consumption
Large feeding capacity and high-pressure extrusion capability, with a production capacity of 300–1000kg/h; energy consumption is only 80–110kWh per ton of pellets, significantly reducing the operating cost of WPC raw material production.

4. Low-Temperature Processing Protection
PE pelletizing machine adopts low-shear, low-temperature extrusion technology to inhibit thermal degradation of wood fiber, retaining the fiber’s original toughness; the produced pellets have stable melt flow index, ensuring smooth and consistent WPC decking extrusion.

Parallel twin screw pe pelletizing machine operation mainly includes the following steps:

1. Raw Material Pre-mixing
Add PE recycled pellets, wood powder, calcium powder and additives into the high-speed mixer in proportion; mix thoroughly at a controlled temperature to ensure uniform dispersion of all components without agglomeration.

2. Twin-Screw Extrusion & Compounding
The materials enter the tapered twin-screw barrel, where they undergo gradual heating, melting, shearing and kneading; the cone screw’s unique structure generates high pressure to fully fuse PE matrix with wood fiber and calcium powder, inhibiting fiber degradation at low temperature.

3. Melt Extrusion & Pelletizing
The well-compounded molten material is extruded through the die head to form uniform strips; the strips are then sent to the pelletizer for high-speed cutting to produce pellets of Φ2–4mm (customizable size).

4. Cooling & Screening
The newly cut pellets are cooled rapidly by air or water to stabilize their shape and performance;

After cooling, the pellets pass through a vibration screen to remove oversized or undersized particles, ensuring consistent pellet size. Adding vibration is according to client’s requirements.

When using the parallel twin screw PE pelletizing machine, there are the following precautions:

1. Raw Material Preparation & Pre-treatment
Ensure PE recycled pellets, wood powder and calcium powder are fully dried before feeding; remove impurities like metal particles from raw materials to prevent screw wear or barrel damage.

2. Feeding Parameter Calibration
Follow the recommended material ratio strictly; adjust the frequency conversion feeding speed according to the actual extrusion status, avoiding over-feeding (which causes barrel blockage) or under-feeding (which reduces production efficiency and pellet quality).

3. Temperature Control in Extrusion Process
Set a gradient temperature curve for the cone twin-screw barrel (recommended 140–180℃) based on material properties; avoid excessive temperature that leads to wood fiber degradation and PE melt aging, which will affect the performance of WPC decking pellets.

4. Screw & Barrel Maintenance
After daily production, clean the screw and barrel of PE pelletizing machine; avoid leaving mixed materials inside for a long time to prevent material carbonization and subsequent contamination of new batches.

5. Cooling & Screening System Check
Regularly inspect the cooling fan/water circulation system to ensure stable cooling effect; clean the vibration screen mesh periodically to prevent screen clogging and ensure accurate pellet size sorting.

6. Safety Operation & Compliance
Operate the PE pelletizing machine in accordance with CE safety standards; ensure emergency stop buttons are functional at all times. Do not disassemble any parts during machine operation to avoid safety hazards.
