Water Ring Pelletizing System
Suitable for certain recipes, such as PE, PS, EVA and TPU. The final pellet looks nicer and has good flowability, and the production line is shorter than that of strand pelletizing.
- PE / PP filler masterbatch
- TPV / TPE
- EVA
- Soft PVC
- PS
- TPU
Twin screw extruder with water ring pelletizer, centrifugal dewatering and classifier
