Single-screw Extruder (KE)
Features
Product information
KraussMaffei Extrusions single-screw extruders are characterized by their simple and robust machine design, low maintenance requirements, maximum torques and free design of the process part. Due to the variable design options, the single-screw extruders are used for a wide variety of process tasks worldwide.
Performance data
Screw diameter: 250mm to 800mm
Throughput from 10t/h to 74t/h
Up to 1.4 million Nm torque
Why our product stands out
- High cooling performance due to "wet" liners, pressurized water and optimized screw profiles
- Highly efficient melt degassing for the removal of residues and monomers from the melt with or without stripping agent
- Modular design of the extruder for quick installation on site, simplified foundation work and flexible configuration of the process part
- Planning, delivery and installation of complete extruders including auxiliary and downstream equipment (e.g. dryer, pressurized water system, classifier) e.g. dryer, pressurized water syst
- Optimized for products such as LDPE, EVA, POE, and acrylic copolymers
Variants
Virgin Polymers
In the discharge extruder, additives can be homogeneously incorporated and melt temperature precisely controlled. The modular design of the KE single-screw extruder ensures process reliability, flexibility, and effective devolatilization. Powerful vacuum systems remove volatiles efficiently, delivering optimized processing and consistent product properties in polyethylene as well as homo- and copolymers.
Schaumtandex
The Schaumtandex process uses a downstream cooling extruder to efficiently and homogeneously cool the melt prepared in the twin-screw extruder. This enables extremely high throughputs of up to 7,600 kg/h, making it ideal for producing large, high-quality foam boards and beads. The system ensures maximum process safety, efficient cooling, long service life, and the ability to process up to 100% recycled material.
Schaumex
The Schaumex extruder combines all process steps – from melting and incorporation of the blowing agent to cooling – in a single processing unit. This allows particularly space- and cost-efficient production of foamed sheets, pipes, and profiles at small to medium throughputs. High automation, ease of operation, and flexible customization make the system ideal for tailored production requirements.
