The German plant manufacturer GETECHA will be providing information at this year’s Fakuma about its comprehensive range of services for implementing automated shredding solutions for the plastics and recycling industry. In Hall A3, he will use numerous exhibits to show how users of injection molding, extrusion, thermoforming and blow molding technology can shred and reuse their production residues efficiently and in a resource-saving manner. As a special highlight, the company is presenting its new RS 150 compact mill, which is tailored to crushing sprues directly on the injection molding machine.
Eva Rosenberger: “Our new compact side mill RS 150 is a cost-effective, versatile all-rounder for the production-integrated shredding of sprues and light missing parts. It guarantees excellent regrind quality even when processing TPE and POM and scores points with its low energy consumption.” (In the picture: a GRS 300)
Plastics processors, recycling experts and recyclate manufacturers who are looking for competent partners at Fakuma for projects relating to modern shredding technology should plan a visit to booth 3210 in Hall A3. Here, plant manufacturer GETECHA presents a wide range of machines and services for the implementation of automated system solutions for the efficient shredding of waste, missing parts and leftovers from production. The focus is on various hopper mills, flexible feed and discharge technology and, last but not least, all the engineering skills with which the company knows how to handle even demanding tasks. A highlight of GETECHA’s Fakuma appearance this year is the presentation of the new RS 150 cutting mill – tailor-made for direct use in injection molding technology lines.
“This compact side mill is a cost-effective and versatile all-rounder for the production-integrated shredding of sprues and light defective parts. It ensures excellent regrind quality even when processing TPE and POM, scores with low energy consumption and, thanks to its envelope dimensions of 674 x 435 x 775 mm, takes up little space. “It also requires minimal maintenance,” explains 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 adjusted to feed heights of around 775 to 1,280 mm, has a strong three-blade rotor in horizontal design and is prepared for connection to a customer-provided vacuum extraction system. Their design allows flexible adaptation to different production conditions. For example, the rotor variants, drives and knife qualities can be designed for each specific case and the hopper can be designed for feeding via a sprue picker or manual insertion. Intervention protection is already secured from a low loading height of 775 mm, and depending on customer requirements, the new RS 150 is available with a low or high frame.
The GRS 180 A side mill has wear protection plates in the hopper, so that in conjunction with the wear-protected carbide blades of its seven-blade rotor, it can also handle abrasive material
“Fill level monitoring prevents the container from being overfilled, so that there is no material backing up into the grinding chamber. A warning signal can be issued or a suction conveyor can be activated so that the production process always remains stable,” explains Eva Rosenberger. GETECHA optionally equips the new side mill with modern sensors that record utilization and consumption in the context of an entire system and allow the system to react in a targeted manner in order to reduce consumption and release the system’s operating reserves.
Wear-resistant to abrasive materials
In addition to the new RS 150, GETECHA is showing several mill models at Fakuma that prove themselves day after day in many areas of plastics and recycling technology. For example, the side mills of the GRS 180 series, whose domain is also the crushing of sprues and missing parts from injection molding technology. The hopper version is also suitable for manual or automatic feeding via the handling system.
The GRS 180 system optionally has wear protection plates in the hopper, so that in combination with the wear-protected carbide blades of its seven-blade rotor, it is also suitable for abrasive material. An optional water-cooled grinding housing reduces the thermal load on the material to be ground and prevents it from plasticizing in the grinding chamber. The nominal power here is 2.2 kW and is effectively reduced to around 1.1 kW under load through the use of the GETECHA EnergySave system. “We also offer a screw feeder for positioning under the SGM as well as a lock funnel for productions with increased cleanliness requirements,” explains Eva Rosenberger.
On the GRS 300 A GETECHA – here in the open state – the inclined ten-blade rotor driven by a 5.5 kW motor allows the system to start up even when partially filled
Designed for higher hourly output
For plastics processors and recyclers with higher demands on shredding technology, GETECHA will be showing at its Fakuma stand a GRS 300 A that is raised into a collecting container and can be moved on rollers so that the regrind can be stored freely. It can be used as a small central mill or large auxiliary mill for shredding sprues and missing parts . The inclined ten-knife rotor of this hopper mill, 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 knives in HSS quality shred up to 80 kg of material per hour. And as Eva Rosenberger emphasizes, “this mill also scores points with its easy cleaning and tool-free screen changing”.
The RS 2404 A, which GETECHA is showing at Fakuma, is designed for an hourly shredding performance of up to 160 kg of material. This compact central mill, which also has roller bearings, has a mill body and a feed hopper in a double-walled, sound-insulated design, a front feed hopper for loading by hand or via feed belt and an open three-knife rotor with attached knives (drive power 5.5 kW). It can be seen at the trade fair with integrated extraction, a sound-insulated conveyor fan as well as exhaust air dedusting and the GETECHA GE 12 regrind dedusting system.
As the largest model in its extensive mill park, GETECHA is presenting an RS 38060 A at Fakuma this time for efficiently shredding blow-molded containers and injection-molded parts
As the largest model in its extensive mill park, GETECHA is presenting an RS 38060 A at Fakuma this time for efficiently shredding blow-molded containers and injection-molded parts. This central mill, powered by a 22 kW motor, is a universally applicable system, which in the trade fair version is designed to process containers and slugs of up to 60 dm³. The hopper is generously sized and its design is very maintenance-friendly: the screen carriage runs on rollers and can be completely and easily extended without tools. “The mill’s other plus points include the optimally coordinated rotor and the hand hydraulics for convenient opening of the hopper,” explains Eva Rosenberger.
Analysis and integration
Overall, GETECHA’s current service catalog offers modern shredding technology for volumes from 10 to 5,000 kg/h. All of the company’s mills are now characterized by a design that has been thought through down to the last detail, which can be tailored to the customer’s specific needs and enables low-maintenance, energy-efficient operation. The plant manufacturer’s high level of consulting expertise includes the analysis of the individual application and the integration of the shredding solution into the customer’s infrastructure, which usually opens up additional savings and optimization potential. All GETECHA shredding systems can be controlled automatically and integrated into the customer’s IT infrastructure.
