Pelletizer Screw Barrel

At Laizhou Yuening Machinery, we build screw barrels specifically for plastic pelletizing and recycling lines, focusing on durability and real-world performance. These are core wear parts for LDPE/HDPE/PP granulators, made to handle everything from thin film flakes to hard engineering plastics like ABS, PS, and EPS. Whether you're running a small-scale film recycling line or a high-volume continuous pelletizer, our screw barrels are sized to match your machine's output and material needs.

The vented port design is one of the key practical features we include. During plastic recycling, even washed material still holds residual moisture and volatile compounds. Without proper venting, these get trapped and cause bubbles, uneven melting, or inconsistent pellet quality. Our screw barrels include a dedicated vent section that lets these gases escape cleanly during processing, keeping the melt stable and the final pellets uniform.

Durability is the other focus. These parts see constant friction with abrasive plastic waste, so we build them to last. The barrel and screw are precision-machined for a tight fit, with surfaces treated to handle the heat and wear of long runs. The result is longer service life, less frequent replacements, and fewer unexpected stops in your production line.

Each size comes with matching screw and barrel dimensions, including optional screw diameters to suit different material characteristics. This makes them easy to swap into existing granulators, with minimal downtime during replacement.

In practical use, these screw barrels are most commonly used for film recycling lines processing LDPE/HDPE/PP scrap, as well as mixed rigid plastics. They're also found in manufacturing plants running continuous pelletizers, where consistent melting and long component life are critical to meeting production targets.

Based in Laizhou, Shandong, we're located in the heart of China's plastic machinery industrial cluster. We've been making plastic recycling equipment for years, so we understand the wear and tear these parts go through on the shop floor. Every screw barrel is inspected before shipping, with outgoing inspection video provided for your records. We back them with a 1-year warranty on core components, so you can run your line with confidence.
