Product Overview

The Single Screw Water Ring Pelletizer is an industrial plastic recycling system designed for continuous pelletizing of thermoplastic materials such as PE, PP, HDPE, ABS, and mixed plastic waste.

The system integrates extrusion, melt filtration, water ring cutting, pellet cooling, dewatering, and drying into a stable and continuous production process.

It is widely used in plastic recycling plants and reprocessing industries where stable output and reliable operation are required.

Application Experience

Our pelletizing systems have been supplied to recycling projects in multiple international markets, including the Middle East, Africa, Southeast Asia, and South America.

These systems are used in applications such as plastic film recycling, bottle recycling, and mixed plastic reprocessing.

Working Principle

Plastic materials are fed into a single screw extruder for melting and plasticizing under controlled temperature and pressure.

The molten polymer passes through a filtration system to remove impurities before entering the die head.

At the die face, a water ring pelletizing system cuts the melt into uniform pellets under a circulating water environment.

The pellets are then separated, dewatered, and dried through an integrated system.
