Fakuma 2021 Granulation technology supports recycling efforts of plastics processors
After a Corona-related trade fair hiatus, German machine builder Getecha will be back at this year's Fakuma in Friedrichshafen, Germany. By means of selected exhibits, the company will provide an insight into its portfolio of granulation and recycling systems for use in injection moulding, extrusion and blow moulding technology.
As an eye-catcher, a mighty RS 45090 funnel granulator will form the visual centrepiece of Getecha's Fakuma stand (3210) in Hall A3 this year. With its drive power of 45 kW, its 3-knife rotor and its throughput capacity of up to 900 kg/h, it is one of those medium-sized systems of the Roto Schneider generation that are suitable for central use in plastics and recycling technology. Two stator knives and three or five rows of rotor knives operate in the cutting chamber. The granulator housing has effective sound insulation and, thanks to a drive that is moved upwards and integrated into the housing, the granulator is compact and requires little floor space. At the same time, the version exhibited at Fakuma is an example of customer-specific customisation. Depending on the application and peripherals, the RS 45090 can be expanded with various bypass funnels and turned into a versatile size reduction station. With the appropriate design, a single RS 45090 can replace the working volume of three different applications.
Another exhibit on show is the cleanroom granulator of the GRS 180 series. These slimly designed side granulators have been developed for use in plastics production lines with increased demands on hygiene and cleanliness. Thanks to an airlock funnel, integrated extraction technology and special sealing measures, these granulators release hardly any particles (<1.0 µm). The sluice funnel prevents regrind from being thrown out and also reduces the noise level.
As the “big sister” of this granulator, the Aschaffenburg-based plant manufacturer is also presenting a GRS 300, which — depending on the type of material and screen perforation — processes about 80 kg/h. Its large cutting chamber opening also allows the granulation of bulky castings. Thanks to the split housing and the associated easy removal of the sieve, optimum accessibility for cleaning and maintenance is ensured. In an elevated version, the GRS 300 can be used not only as an auxiliary granulator, but also as a cost-effective small central granulator.
The customised optimisation of the size reduction solutions also applies to the smaller and medium-sized Roto Cutter models. In practice, these are primarily used as decentralised granulators. As examples of this, the company will be showing the RS 2404 mid-range funnel granulator (with integrated extraction) in Friedrichshafen. It has a throughput of up to 160 kg/h and can be used in a variety of ways — both as a small central granulator in injection moulding or blow moulding operations and as an infeed machine for edge strips and film. On the other hand, the RS 1615 auxiliary granulator is again part of this year's Fakuma programme.
Getecha is devoting a great deal of attention to the aspect of energy efficiency across all the granulators in the Roto Cutter families. In addition to presenting its Energy-Safe System, the company will therefore provide detailed information at Fakuma on the drive and control technology options it will be offering its customers in this area in the future.
