Key Points
Optimized for melting and pressure build-up zones
Ensures stable material conveying under full-fill conditions
Equipped with wear-resistant liners for long service life
Closed screw barrels are designed as fully enclosed processing units, providing a controlled environment for material melting and pressure build-up.
Without openings along the barrel body, they maintain a high fill level, enabling efficient heat transfer and stable pressure development. This makes them essential in melting zones and sections requiring consistent material conveying.
Their performance is defined by internal geometry, thermal control efficiency and liner wear resistance, ensuring reliable operation under high temperature and high load conditions.
