Solution Overview

The Twin Screw Water Ring Pelletizing System is an industrial recycling solution designed for stable and continuous pellet production from mixed and recycled plastic materials.

It integrates extrusion, filtration, die-face cutting, water cooling, and drying into one automated production line, ensuring stable output under real industrial conditions.

This system is suitable for plastic recycling plants requiring consistent pellet quality and continuous operation.

Typical Industrial Applications

This system is widely used in:

Plastic film recycling plants

Post-consumer waste processing facilities

Industrial plastic scrap recycling

Compounding and masterbatch production

Real Production Experience

Our systems have been applied in multiple recycling environments with different material conditions:
Southeast Asia: PP film recycling with moisture and contamination

Middle East: PE agricultural film recycling with dust and sand

Europe: Mixed industrial plastic reprocessing for compounding use

Working Principle

Raw Material → Feeding → Twin Screw Extrusion → Melt Filtration → Die Face Cutting → Water Ring Cooling → Dewatering → Drying → Storage

Key Engineering Features

Stable Twin Screw Extrusion
Ensures consistent melting and mixing for recycled materials with unstable composition.

Die-Face Water Ring Cutting
Direct cutting at die surface prevents strand breakage and improves pellet uniformity.

Closed Water Circulation System
Reduces contamination and ensures stable cooling performance.

PLC Automatic Control System
Monitors temperature, pressure, and cutting speed in real time.

Energy Efficient Design
Optimized system reduces energy consumption while maintaining output stability.
