Two new shear granulator models are the focus of Getecha's trade show presentation at this year's Fakuma. According to the manufacturer, these are an exceptionally space-saving version of the cleanroom mill GRS 180 and a particularly robust version of the compact mill RS 2402. In addition, the Aschaffenburg-based system manufacturer presents further innovations in size reduction technology and automation – for example, an extremely quiet central mill and linear technical removal systems.

At Fakuma 2017, the system manufacturer Getecha will showcase, among other things, a modified version of the cleanroom mill GRS 180. This fundamentally very slim-designed slide mill is intended for use in production lines of plastics technology that must meet strict cleanliness and hygiene requirements. It is said to grind up to 35 kg of material per hour and, thanks to integrated suction technology and extensive sealing measures, hardly allows particles to escape into the environment (<1.0 µm).

It is said to grind up to 35 kg of material per hour and, thanks to integrated suction technology and extensive sealing measures, hardly allows particles to escape into the environment (<1.0 µm).

At Fakuma 2017, Getecha is now presenting for the first time a GRS 180 in space-optimized low-profile design. This mill has a total height of only 1,050 mm and is equipped with a roller chassis. It can therefore be easily installed under separation drums, discharge chutes, or large injection molding machines. The space-saving mill design can be realized, among other things, with the help of an extremely flat special hopper, in which a double slide automation ensures the backlash-free feeding of sprues and remnants. Despite the lowered height, this GRS 180 is said by Getecha to be impact- and crush-safe and does not require an additional safety limit switch for position detection. A brake motor guarantees a quick emergency stop in case of failure – for example, if both slides are open simultaneously.

Thick lumps and massive residues

The second innovation introduced by Getecha at Fakuma 2017 is also a model modification. It is a mid-range cone mill RotoSchneider RS 2402, which is often used as a central mill by small injection molding or blow molding companies due to its throughput of up to 100 kg/h. Getecha engineers have optimized this shear granulator so that it can now handle even massive, lumpy, and sticky residues and "sprue cakes." It has been upgraded with a more powerful drive (7.5 kW instead of 4.0 kW), a rotor in a closed design, and a stronger housing. Additionally, the bearings have been deliberately overdimensioned. This could mean for many users that they can now also use the relatively compact RS 2402 for shearing thick-walled lumps, saving the cost of acquiring another mill. Once started, the upgraded RS 2402 operates unmanned and grinds the entire hopper contents without further operator intervention. The closed rotor prevents lumps from sinking too deeply into the grinding chamber, which would otherwise cause the mill to shut down. The ground material is conveyed via a conveyor blower or vacuum conveyor.

Central mill RS 45090 with new grinding housing

Another highlight at Getecha's Fakuma booth is the central mill RS 45090. This large cone mill is designed for throughput rates of up to 900 kg/h and has been equipped since 2016 with a new grinding housing characterized by particularly effective sound insulation. Thanks to its upward-shifted drive, integrated into the housing, it remains compact despite the additional insulation and requires only a relatively small footprint. Some extrusion companies operate the RS 45090 with a second, side-mounted bypass hopper for feeding pipes and profiles, as well as a third rear bypass hopper for sheet material. With this multiple feeding, a single RS 45090 could perform the work of three mills. The high overall stability of the mill, along with its powerful 3-blade rotor and the use of two stator knives in the grinding chamber, are cited as prerequisites for this performance.

An electro-hydraulic opening mechanism facilitates access to the hopper and screen swing, and an electrically monitored rotor lock makes routine blade changes simple and safe.

The proven auxiliary mill RS 1615, with throughput capacities of up to 25 kg/h, is considered a small, additional reduction solution for decentralized use. Thanks to numerous detailed innovations, it is very easy to operate and maintain.

Linear technical removal systems

And as always at its trade show appearances, the Aschaffenburg system manufacturer displays at least one of its linear technical systems for automated removal technology. This time, the focus will be on the fast sprue picker GETpick 500, which can grasp sprues weighing up to 250 g. It operates in the Y-direction with a lightweight carbon fiber tube and offers three operating programs. This aims to achieve removal cycles of less than 1.5 seconds.
