MACHINERY | GRANULATORS
In 2023, Coperion opened a recycling innovation
centre in Weingarten, Germany with individually configurable recycling plants – allowing recyclate to be conveyed, fed, extruded, compounded, pel- letised and deodorised.
Continuous throughput Getecha has developed several central granulators for the continuous throughput of medium to large volumes of plastic waste.

Hellweg has developed a number of digitally controlled grinders
the quality of the finished medical product. Small capacity systems, including injection moulding machines and extruders, are equipped with small diameter plastification screws that cannot process granules with dimensions exceeding those of virgin granules. The G17-MED granulators produce regrind that is dimensionally comparable to the virgin pellet, says CMG.
Entire expertise At Fakuma this year, Coperion and Herbold Meckesheim will show their expertise in entire systems through virtual animation – including systems for recycling plastic. The processes involved can be experienced digitally with the aid of simulation. Rotors from Herbold Meckesheim granulators will be seen in various sizes and for many applica- tions. The cutting geometry is the main reason for the high efficiency the rotors, says the company. Along with individual components, Coperion and Herbold Meckesheim deliver entire systems for plastics recycling. From mechanical processing – shredding, washing, separating, drying and agglomerating of plastics – to bulk material handling as well as feeding and extrusion all the way to compounding and pelletising, such plants cover the entire plastics reclamation process chain. Customers can test a wide variety of plastic
recycling processes and technologies under actual production conditions – in Coperion and Herbold Meckesheim’s fully equipped test centres – before they invest. Herbold’s 800m2
facility in Mecke-
sheim, Germany, includes a complete washing line for cold and hot washing as well as many size reduction solutions including shredders, granula- tors, pulverisers and plastic compactors for densification.
22 PIPE & PROFILE EXTRUSION | Autumn 2024
Designed for comminution capacities of up to 1,000 kg/h, the RS 45090 hopper granulator can grind both missing parts and plates and pipes. For this purpose, it has several bypass hoppers as well as a 45kW motor that drives five rows of mounted rotor blades (rotor diameter 450mm) against two stationary blades. The screen hole diameter is 8mm as standard but can be adapted to different material properties. The front feed hopper of the RS 45090 can be fed manually or is equipped by Getecha with a belt conveyor as part of the process automation. For ergonomic reasons, the hopper and granulator body are double-walled with integrated sound insulation. Thanks to the drive being moved upwards and into the housing, the mill is compact despite its size and takes up relatively little space. The opening mechanism for the hopper and the screen carriage can be operated hydraulically, which simplifies cleaning and maintenance. It also offers smaller central granulators. The RS 30040 is designed for a throughput of up to 360 kg/h with a 22kW drive. It operates with a closed three-blade variation rotor with a diameter of 300mm, in which all components in contact with the product are made of stainless steel. The cutting length here is 410mm. In addition, its RS 2404 can be moved on rollers and has a 5.5kW drive with an hourly throughput of up to 160kg. This small version of a central granula- tor has an open three-blade rotor with attached blades and a diameter of 240mm. The hopper granulator achieves a cutting length of 452mm, says Getecha.
