SIZE REDUCTION | GRANULATORS


It said that recording of power consumption allows conclusions to be drawn about the specific energy input when grinding certain plastics to defined grain sizes. Smart Control evaluates measured power consumption over extended periods of time. The operator can use a digital ammeter in real-time operation and access detailed statistics that have been compiled over long-term operation. Granulation process efficiency can be assessed by comparison with stored reference values, and, if necessary, optimised. Other features include standardised soft starting


of the motor and a new motor brake to enhance energy saving and safety. Power consumption can also be reduced with a new “eco” operating mode, as this adapts rotational speed to input quantity. Hosokawa Alpine has developed the Compact-


Line Granulator 90/200 CL for post-industrial recycling of film waste. With a throughput rate of approximately 4,000 kg/h, the granulator offers higher performance than previous models, with a reduced energy requirement. “The focus in R&D was on maximum suitability for everyday use and high customer benefits,” said Thomas Bässler, Head of Sales & Projects in the Recycling and Granulators Division. Hosokawa Alpine says the patented cross-scis-


sor-cut rotors optimise material intake and distribu- tion. The electrohydraulic opening mechanism for the mill top section and screen support enable quick and easy access to the rotor and cutting chamber. Exact develops film granulators that are relatively small in throughput, most of them using a cold system. The benefits of this approach are that the


company’s machines are low-cost, simple to use and have a very small footprint, said Massimo Mapelli, Exact’s Brand and Communications Officer, at K2019. The company’s R6 series of small machines have throughput rates up to 80 kg/h, its mid-range Evolution 10 can handle medi- um-thickness films at a rate of 150 kg/h, while the Cyklop series is


designed for thick films and run at a rate of 200-300 kg/h (Cyklop 20) and 300-500 kg/h (Cyklop 30). Exact has also been developing hot systems.


The E-60, with a throughput rate up to 75 kg/h, can handle the major PE film types. On its K2019 stand, the company showed the E-120 machine, with throughput of 120-130 kg/h. It is still optimising the machine with selected customers before its full launch in the market. Various granulator companies also showed new


products at K2019. Tria highlighted its XR series granulators designed for thinner extruded materi- als such as PS, PP, PLA and PET. The XR 3530 and XR 5030 models’ main features are: speed regula- tion from 0 to 156 m/min, capability to set to zero the traction unit speed with active accumulator to avoid slipping of rollers and breaking of material during changeover of the reel, remote control with Bluetooth application, and a small footprint. Bruno Folcieri highlighted the Top 1500 D930


from its Easy Power range. The granulators in the Easy Power range are large machines using a heavy steel construction, including the rotor which is made from a solid block of hardened steel forged without any welding. The company says the Top line has features that allow it to maximise efficiency and productivity by guaranteeing high production levels and reduced maintenance times. Another feature is the versatility that allows it to work in either wet or dry conditions, the company said.
