At this year’s K trade fair in Düsseldorf, German plant manufacturer GETECHA will not only be providing insights into its current range of granulators, but will also be presenting a high-quality innovation: a feeding system that eliminates the need for pre-shredding large hollow articles and slugs. The company will demonstrate the added value this brings to process optimization in plastics processing at its booth A09 in Hall 9, using the example of a hopper granulator for medium throughputs.
Here, an infeed granulator for skeleton film from thermoforming; there, a guillotine for processing edge trims from sheet extrusion; and next to it, a beside the press granulator for use in injection molding technology and a foil cutter for low-dust cutting of edge trims—GETECHA is showcasing all this and more at the K trade fair in Hall 9. However, the highlight of this year’s exhibition program is a technical innovation that is sure to make the hearts of many material flow optimizers beat a little faster:

The new HHS feed system, whose innovative character is based primarily on two factors. Firstly, an intelligent metering pusher that feeds the material to be processed horizontally to the cutting rotor depending on the load. And secondly, the option of activating different control programs depending on the material, which regulate the speed and pressure of the feed.
GETECHA is demonstrating what the new system can achieve in practice in Düsseldorf using the RS 38060 hopper granulator as an example. Its energy-efficient and overload-protected 22 kW motor drives a variation rotor (cutting circle 380 mm), whose hydraulic pusher allows even large parts to be accommodated. The new HHS feeding system now enables this granulator to process voluminous hollow articles together with their slugs directly, i.e., without the often time-consuming process step of pre-shredding, into a ground material of the desired grain size. This saves the user both the operation of upstream shredders and all conveyor lines between primary and final grinding. It thus lowers energy costs, reduces technical effort, and saves a lot of time and space.
Premium quality made in Germany
Beyond its role as a case study for the use of the new feeding system, the RS 38060 at K serves to demonstrate the high level of quality that GETECHA achieves in granulator construction. The versatile granulator can handle tangled sprues, packaging returns, film rolls, containers, and other plastic processing residues. It is designed for the reliable grinding of even solid parts, with its robust rotor design offering high operational reliability. The compact design of the granulator also allows for functional expansion through additional modules – such as material discharge via a discharge screw, the use of a control camera in the cutting chamber, or water cooling. The closed, smooth geometry of the cutting chamber is optimized for cleaning when changing materials. Everything about the granulator is designed for easy maintenance, long service life, serviceability, ergonomics, and safety.

| The RS 30090-E infeed granulator |
GETECHA applies the same quality standards to other machines as well. One example is the RS 30090-E infeed granulator, which can also be seen at the company’s K booth. With a three-blade rotor, a 22 kW drive, a knurled infeed, and a self-adjusting dancer arm control, it processes thermoforming skeleton film. Its large rollers also pull in unpunched parts. Alternatively, it can be equipped with automatically speed-controlled feeders and can collect production rejects via a second hopper. Thanks to its sound insulation, the RS 30090-E on display is suitable for use close to the production line. It can be operated with water cooling for grinding thermosensitive plastics.
The other exhibits on display at this year’s K trade fair also give an impression of the wide range of grinding technology that GETECHA currently covers with its portfolio. In addition to its rotary cutters, the company is showcasing its proven FS 200/FS 300 film cutters, which can be integrated into the piping of film processing plants and can handle almost any type of edge trim. The narrow blade gap of only 20 µm between the rotary- and stationary blade enables the grinding of very thin edge trims – regardless of whether they are made of plastic, aluminum, paper, fleece, or veneer material.

| GETECHA’s GH 300 hydraulic guillotine |
Representing its range of guillotines, GETECHA is presenting a GH 300 at K trade fair for the pre-cutting of edge trims from extrusion. Its frequency converter allows the stroke rate to be adjusted to the line speed.
The guillotines are available with various cutting widths, both with electric drives and in a hydraulic version, which can reliably pre-cut even several centimeters thick POM and HDPE residues from sheet extrusion.
