The plastic recycling business may benefit from the greatest efficiency and sustainability provided by NGR's recycling solutions. NGR's robust machines are distinguished by their simplicity, adaptability in use, and zero-waste technology for the greatest level of economic efficiency to support a better future.

Gas control unit
This unit provides quality control by continuously measuring pellet density. Based on preset parameters, the unit determines whether to switch the gates to the second choice or to scrap when this value falls below a setpoint. Monitoring is inline and integrated continuously in the production process.
For continuous melt viscosity measurement. Melt is taken from the production extruder, the viscosity is measured, and then the melt is returned to the extruder.
Based on the differential pressure across the capillary, the viscosity of the material (IV value, MVR) is determined by means of a stored recipe.
Hot die-air pelletizer
Specially designed for inline applications where water is not used. The melt exits through the wear-resistant die plate, and is knocked off by the pelletizer blades. The pellets are carried away in the air stream and cooled.
Hot-die Waterring Pelletizer (HD)
For thermoplastics with a higher viscosity. The melt exits through the wear-resistant die plate, and is knocked off by the pelletizer blades. The pellets cooled in the water ring are flushed out, dried in the centrifuge and discharged. By adjusting the blade pressure, pelletizer blades provide a long service life; replacement is quick and easy.
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.
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.
The throughput scale is integrated in the machine control system and displays the current production output in kg/h (lbs/hr). The data can be logged in a BDE system.
Automatic strand pelletizer (A-SP)
In addition to the benefits of the SP, the A-SP option offers the added convenience of fully automated start-up. The strands are transported automatically by a water slide to the pelletizer, and the pellets are dried in a centrifuge.
Strand pelletizer (SP)
For low-viscosity melts. The melt emerges from strand nozzles, is cooled in a water bath, dried by means of a fan and cut to the desired length in the pelletizer. The result is cylindrical, dust-free pellets with excellent mixing properties.
Underwater pelletizer (UWP)
For difficult-to-process (e.g. sticky) polymers or thermoplastics with a very high melt flow index. The melt emerges from the die plate and is knocked off by the pelletizer blades. The whole process takes place under water. In the centrifuge, the pellets are separated from the process water and dried.
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).
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.
