The PET Flake Pelletizing Line is a high-efficiency recycling system designed to convert cleaned and sorted PET flakes into uniform, high-quality pellets suitable for diverse industrial applications. Engineered for continuous operation, this line ensures consistent pellet size, low moisture content, and excellent material properties, making it ideal for fiber production, bottle reprocessing, and sheet extrusion.

By integrating precise extrusion, rapid cooling, and advanced pellet cutting, the system delivers reliable, high-throughput performance while maintaining material integrity.

System Overview

The line processes PET flakes through multiple stages:

1. Feeding & Drying: PET flakes are loaded into a hopper and passed through a pre-dryer to remove residual moisture.
2. Extrusion: The dried flakes are fed into a high-performance single or twin-screw extruder, where they are melted, homogenized, and filtered to ensure consistent melt quality.
3. Strand Formation: The molten PET is extruded through a multi-hole die to form uniform strands.
4. Cooling: Strands pass through a water or air-cooling system to solidify evenly.
5. Pelletizing: The solidified strands are cut into uniform pellets by a precision strand pelletizer.
6. Classification & Storage: Pellets are separated, cooled, and collected in storage silos or bags.

This structured process guarantees high-quality PET pellets suitable for demanding downstream applications.

Key Components

1. Extruder Unit: High-performance single or twin-screw extruder designed for stable melt, high throughput, and precise control.
2. Die Head & Strand Formation: Precision multi-hole die ensures consistent strand diameter and uniformity.
3. Cooling System: Water or air cooling trough with adjustable flow to optimize strand solidification.
4. Strand Pelletizer: Heavy-duty pelletizer with adjustable pellet size (2–5 mm) and low dust emission.
5. Classifier & Storage: Vibrating classifier and storage silos for efficient pellet collection.
