measure of the machine’s current performance. The reliability, precision and repeatability of the


data generated by Smart Flow is based on the sensor’s operating mode, which uses microwave technology to measure bulk flow. The signal generated by the Doppler effect reflects changes in particle concentration and velocity, enabling an early response. Thanks to contactless measure- ment, the sensor requires no maintenance.


New releases Rapid Granulator introduced several new prod- ucts at K2025 – including its largest granulator yet. Designed for high-volume, industrial-grade


recycling, the 800 Series is optimised for wet granulation applications. It uses an efficient scissor-cut system that reduces wear and saves energy during cutting, while a reversible screen further extends service life and operational uptime. “The 800 Series is the pinnacle of granulation technology for Rapid,” said Anders Martensson, Sales and Marketing Director at Rapid. “It is our largest and most powerful granulator, and introduces a level of operator safety not yet seen in this industry.” It allows for knife changes from the back of the


machine, keeping operators at a safe distance from the rotor and eliminating the need to work within the cutting chamber. The company has also expanded its GT series with the GT1600, which is designed to handle skeletal waste streams from thermoforming processes. Rapid has also taken a step forward in digital


production monitoring with its latest innovation, called Predict, which gives operators instant insights into how their granulators are performing. This can help them perform tasks such as material feeding, operational adjustments, and energy- optimised performance improvements at the production source, to speed up decision-making. Finally, its RMD (rapid metal detection) is a safety solution designed for slow-speed granulators. It instantly halts the rotor as soon as metal is detect- ed – safeguarding the interface between fixed and rotating knives – without interrupting production. RMD is fully integrated into the granulator,


remaining hidden and non-intrusive. Unlike conventional metal detectors, it protects where it matters most, before contaminants reach the cutting chamber, says Rapid. This prevents costly damage to the rotor and knives while minimising downtime and maintaining process continuity. Italy-based Previero Sorema says it continues to evolve its solutions to meet the real needs of plastics recyclers. The latest upgrades to MU 916

and MU 920 granulators “are a clear expression of this approach, combining reliability, ease of use, and enhanced safety to support increasingly demanding production environments”, said the company at the Plast show in June.


Simple maintenance The new versions offer more stable and consistent performance over time, helping operators achieve high-quality output while optimizing operational efficiency, it said. Maintenance has also been made simpler and more accessible. The updated ma- chine structure allows for faster interventions, reducing downtime and making routine operations smoother and more intuitive for operators. Previero said a key strength of the upgraded MU 916 PRH2 and MU 920 PRH2 lies in their flexibility. A wide range of optional features enables each machine to be tailored to specific processing needs, whether dealing with different types of plastic materials or operating in particularly demanding conditions. These options are de- signed to extend component lifespan, improve durability, and ensure long-term performance. Safety has also been a central focus in the development of these upgrades. New solutions have been introduced to provide greater control during maintenance activities, giving operators increased confidence when working on the machine and contributing to a safer overall working environment.
