Extrusion International 6-2020

39 Extrusion International 6/2020 The large free volume and high speci fi c torque enable universal application of the ZE BluePower twin-screw extruders for compounding engineering plastics and even highly fi lled 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-speci fi c ap- plication – from the production of compounds, expanded sheets, biaxially oriented fi lm and sheets up to the pro- cessing of recycled material. Processing section of modular design for uncompromising fl exibility The large extruder variants with screw diameters of 98, 122, 142 and 166 mm still offer the typical screw and bar- rel modularity. Awide range of 4D and 6D barrel housings and various side feeders and degassing units are available for the extruder con fi guration. The exchangeable oval liners ensure ef fi cient wear protection of the housings – a crucial bene fi t in wear-intensive compounding applica- tions in particular. Minor design modi fi cations 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 fl anges and the cartridge heaters are replaced by ceramic heaters.

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 fi rst 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
