Product information
KraussMaffei Extrusion KE single-screw extruders are versatile machines used for a wide range of thermoplastic processing tasks. A common application is their use as melt pumps to build up the necessary pressure for pelletizing. In this role, the KE series offers a key advantage over other methods: it combines high pumping efficiency with minimal energy loss from melt heating, making it both powerful and energy-efficient.
KraussMaffei Extrusion offers time-tested & state-of-the-art machinery for virgin polymer producers worldwide. With extensive know-how in engineering, manufacturing and safe commissioning of extrusion lines for the petrochemical industry, we are a proven and strong partner to our customers. Especially in this field, reliability, uptime and competent support are obligations for the profitability of your enterprise. With our large-scale single (KE series) and twin-screw extrusion lineup (BP and PC series) we can offer efficient tailored solutions for any process demand: novel or established, through licensors, EPC contractors or directly.
Up to 74 t/h throughput
Up to 800 mm single-screw diameter
Up to 8000 h/year
- High cooling performance realized by “wet liners,” pressurized water and screw profiles
- Highly efficient melt degassing of removing residuals and monomers from melt with or without the use of stripping agent
- Unique pelletizer concept (cutting gap, two-stage water chamber) with optimized die plates for excellent pellet quality
- Modular extruder concept – fast on-site installation, simplified foundations, flexible processing areas
- Complete extruder packages – design, supply, and installation including peripherals (e.g., dryers, water pressure systems, classifiers)
Why our Extrusion Line stands out
KE single-screw extruders are characterized by a simple, robust design, minimal maintenance requirements, and virtually unlimited torque. Stabilizing additives can be homogeneously incorporated into the melt. Unwanted melt heating can be mitigated to a certain extent by precisely controlling the barrel temperature.
Specific process requirements such as precise temperature control, high melt homogeneity, and effective degassing of volatiles can be met thanks to the modular design of the KE extruder – which can be tailored to your process through configurable stages.
Applications
LDPE
LDPE is typically processed using a discharge extruder. It is commonly used for tubing, medical equipment, consumer goods, and packaging films.
EVA
Typical EVA applications include foam sheets, shoe soles, hot melt adhesives, sealants, solar panels and coatings.
POE
POE is used in sound deadening applications, as an impact modifier, and as flexible packaging.
Technology Center
KraussMaffei Extrusion’s Technology Center in Laatzen, Germany, offers a state-of-the-art facility for test runs and development projects for all kind of innovations in the extrusion business. One of the highlights is a two-stage extrusion line which offers the opportunity for devolatilization tests. While the first extruder simulates the customers reactor providing a polymer melt still containing solvent and residual monomer, the second extruder removes these substances to prove the efficiency of our machines.
Turnkey Solutions
KraussMaffei Extrusion is a global key player for large single-screw extruders in the LDPE and EVA business and since 1960 it has delivered more than 150 extruders in high pressure plants. During that time the scope of supply has continuously grown and includes nowadays key parts in the downstream equipment as well as vacuum systems, hot oil units, and screen pack changers.
