Description:
The ZE BluePower twin-screw extruder series stands out for numerous innovative features in terms of energy efficiency and process engineering. This series is designed to meet the most demanding market challenges as to output rate, product quality, process reliability and flexibility. Benefit from the multitude of energy-saving innovations and the perfectly matched components of this trendsetting twin-screw extruder series.
Thanks to a wide variety of configuration options, the process section of the ZE BluePower can be tailored to specific applications in the compounding of engineering plastics, polyolefins, cable compounds, PVC and master-batch compounds or be adapted to special process tasks.
Higher torque density and increased free volume. The geometrical dimension of screw shaft and screw elements, the screw preloading system and the geometry of the connecting sleeves have been optimized in order to safely transmit and fully exploit the high torque of up to 16 Nm/cm³. Innovative screw concepts with an increased OD/ID diameter ratio of 1.65 give substantially higher output rates at considerably lower energy consumption.

Customized processing section
The modular range of barrel sections with 4 and 6D length and the wide variety of different screw elements ensure maximum flexibility in the development of customized solutions for specific applications. Our proven C-clamp system provides for rapid barrel section changes.

Highly efficient wear protection
Numerous technical improvements of the ZE BluePower
series give substantially increased availability and unparalleled ease of maintenance in 24/7 production mode. To achieve optimum wear protection for all applications, KraussMaffei Berstorff has complemented the range of patented induction hardened or coated barrel sections by new wear liners. Thanks to unparalleled fitting accuracy and axial fastening, the elliptical shoulder liners provide optimum heat transfer and perfect tightness of the processing chamber.

Effective cooling
The new valve and distributor technology and changed spiralshaped cooling channels give more efficient cooling of the processing section and thus reduce the pressure loss within the temperature control system.

User-friendly base frame concept
The ZE BluePower series features a new base frame concept, which ensures easy and rapid access to the different machine components. With this application-oriented solution, peripheral equipment and control systems can either be integrated into the base frame or mounted separately.

Application:
Engineering plastics, polyolefins, cable compounds, PVC and master-batch compounds or be adapted to special process tasks
