• The conveyor belt is the easiest type of material feeding. Due to its large hopper cross-section large and heavy pieces of material can be handled. A detector provides a warning of metal items in the scrap.
• With an air separator flakes can be blown into a storage silo. An intermediate storage of material is no longer required.
• With an additive dosing device in the section between the shredder and the extruder intake additives equal to up to 20% of the material flow can be fed in (e.g. for the improvement of flow characteristics or material coloring).
• If required we offer a venting system for degassing (drying) the melt using a water ring vacuum pump.
• For highly printed and damp plastics we recommend double venting/degassing.
• NGR offers combined venting consisting of both atmospheric and vacuum venting for materials with a maximum of 10% surface moisture.
• A high-quality, double piston automatic screen changer (melt filter) allows „on-the-fly“ screen changes without stopping the machine.
• Self-cleaning back flushing melt filters are recommended for highly contaminated materials.
• Hot die (water ring) pelletizer is generally used for the majority of polyolefins (PE, low-MFI PP, etc.)
• Strand pelletizer or underwater pelletizing are employed for PA, PET or other polymers as well as for high-MFI PP.
• Typically, NGR supplies the entire pellet transport equipment such as blowers, piping, cyclones, etc.

• Simple ON-OFF-switching: following sudden plant stops (e.g. power loss, emergency stops), the machine can be immediately restarted without any problem with filled hopper and extruder screw.
• The uniform pellet size allows it to be mixed homogenously with original material.
• A high degree of process stability minimizes the influence of the operating personnel on pellet quality
• Simple access to wear parts reduces scheduled downtime to a minimum.
• Robust design, high-grade materials and top quality manufacturing in combination with the finest possible controls and proven electronics, guarantee a long service life.
• Due to the excellent output rate in combination with low operating and energy costs the machine typically offers an extremely short payback period (6-12 months). We are pleased to calculate both your recycling operational costs per kg [lbs] and the payback period.

F:GRAN recycling machines with an extruder screw diameter up to 125 mm [4,92 inch] are equipped with a feeding hopper, an horizontal feeding screw and a force feeding system. The feeding hopper of machines with extruder screw diameters between 145 [5,71 inch] and 205 mm [8,07 inch] is a block silo positioned above the horizontal feeding screw feeding the extruder directly.
