Powerful and highly efficient
Successful market launch of the four large ZE BluePower compounding extruders

The sales launch of the four large ZE BluePower compounding extruders with a throughput capacity of 2,500 kg/h and more started immediately after the K 2019 exhibition (16 to 23 October 2019). The unique combination of high throughput rates and short set-up times has been extremely well received among numerous large national and international compounding companies. The first machines of this type designed for classical compounding processes as well as for reaction and degassing applications have already been put into operation during the last few weeks.

The large free volume and high specific torque enable universal application of the ZE BluePower twin-screw extruders for compounding engineering plastics and even highly filled formulations. Thanks to the 1.65 OD/ID diameter ratio and the torque density of 16 Nm/cm³, these extruders are tailored for any customer-specific application – from the production of compounds, expanded sheets, biaxially oriented film and sheets up to the processing of recycled material. 

Processing section of modular design for uncompromising flexibility

The large extruder variants with screw diameters of 98, 122, 142 and 166 mm still offer the typical screw and barrel modularity. A wide range of 4D and 6D barrel housings and various side feeders and degassing units are available for the extruder configuration. The exchangeable oval liners ensure efficient wear protection of the housings – a crucial benefit in wear-intensive compounding applications in particular.

Minor design modifications have been implemented by KraussMaffei to allow for the size of the new extruders. The housing elements are connected by means of screw unions instead of clamping flanges and the cartridge heaters are replaced by ceramic heaters.
