Technological expertise and a premiere

GETECHA presents its new RS 150 compact granulator series at Fakuma

At this year’s Fakuma, the German plant manufacturer GETECHA will be presenting its comprehensive range of services for the realization of automated size reduction solutions for the plastics and recycling industry. In Hall A3, the company will be showcasing numerous exhibits demonstrating how users of injection molding, extrusion, thermoforming and blow molding technology can grind and reuse their production waste efficiently and in a resource-saving manner. As a special highlight, the company will be presenting its new RS 150 compact granulator, which is tailored to the grinding of sprues directly at the injection molding machine.

Plastics processors, recycling experts and recyclate manufacturers who are looking for competent partners for modern grinding technology projects at Fakuma should plan a visit to stand 3210 in hall A3. This is where plant manufacturer GETECHA will be presenting a wide range of machines and services for the realization of automated system solutions for the efficient grinding of waste, offcuts and residues from production. The focus will be on various hopper granulators, flexible feed and discharge technology and, last but not least, all the engineering expertise with which the company knows how to master even the most challenging tasks. Another highlight of GETECHA’s appearance at this year’s Fakuma is the presentation of the new RS 150 granulator, which is tailor-made for direct use in injection molding technology lines. “This compact granulator is a cost-effective and versatile all-rounder for the production-integrated grinding of sprues and light faulty parts. It guarantees excellent regrind quality even when processing TPE and POM, scores points for its low energy consumption and takes up very little space thanks to its envelope dimensions of 674 x 435 x 775 mm. It also requires minimal maintenance,” says Eva Rosenberger, Sales Manager and Shareholder at GETECHA.

Efficient, compact and flexible

The new RS 150 is a hopper model for manual or automated material feeding via the handling systems of injection molding machines. It can be adapted to feed heights of around 775 to 1,280 mm, has a powerful three-blade rotor in a horizontal design and is prepared for connection to a vacuum extraction system provided by the customer. The design allows flexible adaptation to different production conditions. For example, the rotor variants, drives and blade qualities can be designed specifically for each case and the hopper can be designed for feeding by sprue picker or manual feeding. Intervention protection is ensured from a low feed height of 775 mm and, depending on customer requirements, the new RS 150 is available with a low or high frame. “A fill level sensor prevents the material box from overfilling, so that material cannot back up into the cutting chamber. Optionally, a warning signal can be issued or a hopper loader can be activated so that the production process always remains stable,” explains Eva Rosenberger. As an option, GETECHA can equip the new beside-the-press granulator with modern sensor technology that records the capacity utilization and consumption in the context of an overall system and allows the system to react in a targeted manner in order to reduce consumption and release the system’s operating reserves.

Wear-resistant for abrasive materials

In addition to the new RS 150, GETECHA will be exhibiting several granulator models at Fakuma that prove themselves day after day in many areas of plastics and recycling technology. For example, the GRS 180 series of granulators, whose application is also grinding of sprues and faulty parts from injection molding technology. The hopper version is also suitable for manual or automatic feeding via the handling system. The GRS 180 system has optional wear protection plates in the hopper so that it is also suitable for abrasive material in combination with the wear-protected hard metal blades of its seven-blade rotor. An optional water-cooled cutting chamber reduces the thermal load on the material to be ground and prevents it from plasticizing in the cutting chamber. The rated power here is 2.2 kW and is effectively reduced to around 1.1 kW under load by using the GETECHA EnergySave system. “We also offer a screw feeder for positioning under the injecting molding machine and a sluice hopper for productions with increased cleanliness requirements,” explains Eva Rosenberger.

Designed for higher hourly throughput

For plastics processors and recyclers with higher demands on size reduction technology, GETECHA will be exhibiting a GRS 300 A at its Fakuma stand, with a higher frame and moved on rollers for free regrind discharge into a collecting container. It can be used as a small central granulator or a large beside press granulator for grinding sprues and faulty parts. The inclined ten-blade rotor of this granulator, driven by a 5.5 kW motor, allows the system to be started up even when partially filled. At rotor speeds of 230 rpm and depending on the type of plastic and screen perforation, its wear-protected blades (HSS quality) grind up to 80 kg of material per hour. And as Eva Rosenberger emphasizes, “this granulator also scores with easy cleaning and tool-free screen changes”.

The RS 2404 A, which GETECHA will show at Fakuma, is designed for an hourly grinding capacity of up to 160 kg of material. This movable compact central granulator has a cutting chamber and a feed hopper in a double-walled, sound-insulated design. The parts will be feeding by hand or by conveyor belt and grinded by an open three-blade rotor with attached blades (drive power 5.5 kW). The granulator can be seen at the fair with an integrated extraction system, sound-insulated conveying fan, exhaust air dedusting unit and the GETECHA GE 12 regrind dedusting system.

As the largest model in its comprehensive range of granulators, GETECHA will be presenting an RS 38060 A for the efficient size reduction of blow-molded containers and injection-molded parts at this year’s Fakuma. This central granulator, which is driven by a 22 kW motor, is a universally applicable system that is designed to process containers and tops and tails of up to 60 dm³ in size. The feeding hopper is generously dimensioned and its design is very easy to maintain: the screen carriage runs on rollers and can be complete and easily extended without tools. “Other plus points of the granulator include the optimally tuned rotor and the hand hydraulics for easy opening of the hopper,” says Eva Rosenberger.

Analysis and integration

Overall, GETECHA’s current service catalog offers modern grinding technology for volumes from 10 to 5,000 kg/h. All of the company’s granulators are characterized by a design that has been thought through down to the last detail, can be customized and enables low-maintenance, energy-efficient operation. The high level of consulting expertise of the plant manufacturer includes the analysis of the individual application and the integration of the grinding solution into the customer’s infrastructure, which usually opens up additional savings and optimization potential. All GETECHA grinding systems can be automatically controlled and integrated into the customer’s IT infrastructure.
