wood plastic WPC granulating pelletizing machine

WPC Granulating Machine

WPC Granulating Machine uses recycled PP/PE plastic and wood powder as raw material to make WPC granules.

WPC granules can be used or making WPC profiles, such as WPC decking, WPC wall cladding, WPC Post, WPC fence.

The raw material is recycled plastic, Wood Powder,CaCo3 and chemicals, the ratio as bellow:

ItemMaterial nameMixing Ratio
01Recycled PP/PE plastic25-30 kg
02wood powder50-70 kg
03CaCo30-10 kg
04Chemical additivesaround 5 kg

Moisture exhuasting system

This WPC granlation machine designed with good moisture exhuasting system to taking out the moisture in the material,there is 4
holes on the barrel for moisture out,
and there is a suction system on top for taking away the moisture

Smoking collection device

When the material come out from the die head, the moisture and smoking may come out from the die head, we equip good suction
system for taking away the moisture and smoking at die head,
