S:GRAN
The evolution of the market leader
The S:GRAN is the latest development in our successful shredder-feeder-extruder combination, with over 1,200 patented installations worldwide since continuous production began in 1997.
Description
S:GRAN is the perfect solution for processing scrap plastic materials of a variety of types, materials and shapes created by industrial processes. Even thick-walled scrap plastic materials as well as fibers and textiles can be processed without additional pre-shredding.
The plastic recycling technology of S:GRAN meets even the highest standards for efficiency and achieves zero- waste production (all production waste is fed back in) thanks to shredding that conserves an outstanding amount of material as well as optimally guided extrusion.
At a glance
- Simple, high quality processing of post industrial waste of any type
- An evolution of our patented single-shaft shredder/extruder combination.
- Throughput rates up to 900kg/h
- minimal operator interaction, one button, easy start-up and shut-down
- NXT design platform, flexible, modular construction with multiple options
- Faster ROI, and lower OpEx with the latest generation technology
* Output values for LDPE according to NGR company standard, depending on material and quality.
In addition, NGR provides all the equipment for conveying pellets such as blower, pipes, cyclones and much more.
Technology
The operating principle of S:GRAN
Plastic waste is processed by a heavy duty shredder operating at low speed for gentle size reduction and minimal loss of material properties. in this process, a hydraulic ram pushes the material into the shredder drum.
The shredder and extruder drives are controlled separately and automatically, based on load.
After shredding, the material is fed directly into the extruder. in the extruder, the material is brought to a uniform melt temperature and degassed, if necessary.
All the components are positioned in close proximity to prevent oxidation of the material and to make optimal use of heat from the shredding process.
This patented combination of shredder, feeder and extruder is a feature of all units in the S:GRAN line.
One-step-technology
In a single process step, the slow-turning shredder blades grind up the plastic waste and the shredded material is then fed continuously to the extruder.
Process bulky plastic scrap
Large, thick or bulky waste can be processed without pre-shredding as long as pieces fit into the hopper opening.
One-button automatic ON/OFF control
The control system provides for smooth start-up of equipment components. Restart after unplanned shutdown in less than two minutes with full hopper and full extruder.
Dump and run operation
The material level in the hopper is constantly measured and the feed is regulated accordingly. Discontinuous filling of the conveyor is possible – the NGR control unit does the rest.
Extruder screw
Extruder screw
Specially developed for the challenges of recycling, the universal extruder screws provide optimum melt homogeneity and process material efficiently with minimal loss of physical properties. For special requirements, our expert NGR engineers develop custom-tailored screw geometries.
Control unit
Control unit
All equipment functions from feeding to pelletizing are controlled automatically from the easy-to-read NGR touchscreen. Recipes are managed in the operator control unit, which increases traceability, provides ease of use, and ensures equipment parameters are set properly.
High-quality pellets
Pellet size
In addition to high quality, the uniform pellet size also provides for homogeneous mixture in new material. NGR thus plays an indirect role in ensuring consistent quality in the final product.

Feed-in
Air separator
Air Seperator
The air separator is used in the production process to continuously recycle film edge trim, which is fed pneumatically into the machine. With “inline operation,” further material handling is unnecessary, and the NGR recycling machine is now fully automated.
Roll feeder
Roll Feeder
With variable feed speed, roll scrap is treated in a process-controlled manner. The virtually unmanned machine is fed continuously. The roll feeder can be operated at the same time with other types of feeding (e.g. conveyor belt).
Conveyor belt
Conveyor belt
The conveyor belt transports the feed material through a metal detector into the feed hopper. The belt is stopped automatically, if metallic matter is detected in order to remove it.
Dosing unit
Dosing unit
Additives such as color pigments, CaCo3, compatibilizers can be added to the material flow in a process-controlled manner. Dosing systems for pellet and/or powdered additives are available.

Solid engineering, high-quality materials and precise execution ensure a long service life for equipment.
maintenance-friendly access to moveable parts allows you to quickly change material, efficiently disassemble and assemble wear and tear parts, and minimizes downtime.
The solidly-constructed, low-speed shredder combined with hydraulic-driven pusher also provides efficient shredding of bulky plastic scrap.
Testimonials
In our company,there are 3 NGR machines, E:GRAN and two S:GRAN which are taken at various times. These machines are easy to use. Production and Labor Safety in the forefront. The automation system of the machine has been selected from the brands that maintainers can easily reach. PLC and motor drives can be easily backed up. Operators can easily use the operator panel. And the service that NGR offers, is fully dependable and trustable. Thank you NGR for your excellent cooperation
Abdülaziz Aktaş, Factory Manager
Sekuro, Turkey
NGR is probably the best recycling m/c we have come across. It is operator friendly and once the parameters are set it runs automatically . We have been running this m/c round the clock since August 2018 and never faced any serious problem. We have recycled more than 600 MT of waste till date.
Rajagopalan Balasubramaniam, Plant Head
Woven Sacks & FIBC manufacturer, India
Operating the NGR machine, 24h a day, for the last 4 years, I can surely say that it is most reliable. Further it would have been an omission, not to highlight the fact , that I enjoy the undivided and prompt support of the NGR after Sales, which are one of the best in the field I working at.
