Perfectly produced. Perfectly recycled. Contaminant removal and sorting of material flows into pure fractions throughout the complete PET product life cycle Inspection of PET granulate prior to injection moulding PET granulate may contain small metal particles that during processing will contaminate the melt and cause expensive malfunctions in the injection moulding of preforms and caps. S+S magnets and metal separators will remove magnetic and non-magnetic metal particles from PET granulate and protect injection moulding machines from damage. PET recycling with high added value S+S has...

Separation and Sorting systems PET recycling. Systematic Separation and Sorting. From whole bottle sorting through to high precision PET flake separation – S+S covers the complete range of contaminant separation and material flow sorting. S+S systems are of a modular design – matched to individual customer specific applications – optimal components are combined in one system. PET bottle sorting – A basic concept for many applications. PET bottle sorting systems of the VARISORT series feature a modular design, sensors can be combined or retrofitted depending on the application. All...

Foreign plastics 1 Overband magnet 2 Drum magnet Coloured PET bottles VARISORT M The VARISORT M metal separator automatically separates metallic contaminants (e.g. cans, tetrapack) from the PET bottle flow. VARISORT N In PET recycling the VARISORT N polymer separator automatically separates unwanted plastic types (e.g. PLA, PVC, HDPE) from the PET bottle flow. VARISORT C The VARISORT C colour separator automatically separates unwanted colour contaminations (e.g. coloured from clear, non-transparent bottles) from the PET bottle flow.

Separation and Sorting systems PET bottles Manual sorting 1 Tunnel metal detector 2 Single-face metal detector PET flake sorting – Modular concept for high quality. Up to three sensors can be combined in the PURIFIER series: M Inductive sensor for metal detection C Optical sensor for colour detection N Multi-spectral sensor for the detection of foreign particles and plastic types These sensors are combined to match the application. When the sorting requirements change, systems with one sensor type can at any time be upgraded with additional sensor components. For the removal of larger metal...

Foreign plastics Sink/float process 7 GF metal separator 8 RAPID metal separator FLAKE PURIFIER M metal separator automatically separates metallic contaminants from the PET flake flow. FLAKE PURIFIER C colour separator automatically separates out of specification colour contaminants from a PET flake flow. FLAKE PURIFIER N polymer separator automatically sorts different plastic types according to their infrared absorption properties.

Metal detectors and separators – Magnetic separators Metal-free production – Machinery and mould protection Safe detection and separation of metal contaminants from PET granulate S+S metal detectors and separators detect and separate ferro- Incoming goods magnetic metals, stainless steel, aluminium, copper, brass, lead and all other metals from PET granulate (virgin and recyclate), irrespective of whether metal contaminants exist in sheathed, coated, painted, insulated, enclosed, or individual form. Magnetic Granulate Production separators are mainly used for the pre-separation of ferrous...

Granulate Production Production Regranulation Preform injection moulding machine Twinscrew extruder Singlescrew extruder RAPID metal separator series For free-fall applications. Metal contaminants are separated by a reject flap ("Quick Flap System") without interruption of material flow. The RAPID series covers a wide variety of applications. PROTECTOR Metal separators for low throughput rates and installed at the infeed of processing machines. PROTECTOR series are also available for high temperature applications. SAFEMAG inline magnet The SAFEMAG magnet system is specifically designed for...
