Film Division
The film technology division of Hosokawa Alpine, one of the leading suppliers in the field of process engineering and blown film extrusion, is presenting its latest developments and current components for efficient film production at interplastica 2020 in Moscow. The plastics sector faces major challenges in view of the increasing demands for efficient use of energy and resources and high standards of quality for flexible packaging. As a technological pioneer, Hosokawa Alpine offers a wide range of appropriate solutions for future-proof system configurations. The new HX Select extruder series, for example, features an innovative cylinder and screw design for up to 50 per cent higher output, with at the same time an energy saving of up to 20 per cent versus standard barrel extruders.
Another highlight presented by Hosokawa Alpine is a complete cooling system, consisting of the new Alpine CRX cooling ring series for outer cooling as well as the also new Alpine HT cooling tower for inner cooling. The low-counterpressure system achieves energy-efficient use of existing cooling capacity and guarantees optimum film quality with maximum output.
The Alpine ASW screen changer will also be presented as an additional innovation. The screen changer developed by Hosokawa Alpine blends perfectly into Alpine systems and makes for maximum efficiency. The new Alpine HWD winder ensures perfectly wound films. The latest-generation winder combines the advantages of flatbed and turret winders in a single machine and allows high winding speeds with perfect film quality. The two digital tools, Hosokawa Alpine Isa and ExVis 5.0, round off the system portfolio. Hosokawa Alpine Isa is a central digitisation platform, developed from scratch, that can read out, save, display and analyse process data from the widest range of plant types. The update to version 5.0 gives the tried and trusted ExVis process visualisation tool many additional new features, in addition to a more neatly structured and convenient user interface. This transforms ExVis into a fully networked system in which the data of all system components can be merged and managed.
Recycling Division
Among others, Hosokawa will present a robust high-performance granulator. The efficient recycling of production waste within the framework of a closed material circuit is becoming increasingly important. Hosokawa Alpine sets standards here thanks to its decades of experience. The Rotoplex model from the granulator product line has proven itself to be particularly successful for the reliable size reduction of all kinds and shapes of plastic waste. This classic granulator from Hosokawa Alpine is constantly refined and improved and makes its mark even in the current seventh generation by virtue of its reliability and top performance.
The high-performance granulator is characterised by its robust design in high-grade spheroidal graphite cast iron in GGG 40 quality, the positive connection of the stator knives as well as a solid and efficient cast rotor. "Besides a sharp cut, our patented cross-scissorcut rotor guarantees a verifiably reduced energy consumption of as much as 20 per cent compared with conventional cutting techniques," underlines Bernd Kneisl, Operations Director of the Recycling & Granulators Division of Hosokawa Alpine’s process technology business segment. Above all when high cutting performance is called for, the Rotoplex granulator - as for example the exhibited 50/80 Ro - shows its true strength. Dependent on the material and screen perforations, the granulator achieves throughput rates of up to 1000 kg/h.
Over and above the high cutting power, the Rotoplex 50/80 Ro has numerous other design features which guarantee immediate benefits to users. Once the top section has been opened, the cutting chamber is easy to access. Which means that cleaning procedures as well as knife or screen exchange are quick and uncomplicated. This serves to prevent long periods of downtime. In addition, the special shaft bearing prevents penetration of the product into the bearing as well as the ingress of excess lubricant into the cutting chamber.
