VARISORT CME-P - Combined colour and metal separation system for plastics recycling applications (material fed by conveyor)
The VARISORT CME-P combined colour and metal separator is designed for use in the plastics recycling industry to remove metal (cans, foil-lined Tetrapaks etc) and off-colour contaminants (bottles, cups etc) from plastic bulk materials. The material to be inspected is spread out on a fast-moving conveyor so that the pieces are optimally individualised before they reach the inspection area of the multi-channel metal detector. If a contaminant is detected its exact location is determined. Electronics evaluate this position and ejection nozzles are activated with pinpoint accuracy and at precisely the right time to blow out the contaminant. The ejection nozzles are so precise that the metal and off-colour contaminants are removed with very little loss of good material and without any interruption to the material flow.
Advantages:
• removes metal, metal composites and inclusions
• removes contaminants with pinpoint accuracy
• modular design
• evaluation of the entire visible light spectrum
• self-teaching evaluation electronics
Typical applications:
• removes cans from lightweight packaging
• removes off-colour plastic bottles
• removes metals/off-colours from specialized plastics

SPEKTRUM CE-G
Off-colour separation system for glass recycling applications
Spektrum colour separation systems are designed for the glass recycling industry to remove off-colours from glass cullet. The material to be inspected is spread out on an external feeder and reaches the glass slide where the pieces are further individualised before continuing into the inspection area of the CCD linear camera. If an off-colour contaminant is detected its exact location is determined. Electronics evaluate this position and ejection nozzles are activated with pinpoint accuracy and at precisely the right time to blow out the contaminant. The ejection nozzles are so precise that the contaminant is removed with very little loss of cullet. The rest of the cullet then continues along the conveyor.

SPEKTRUM CE-P
Off-colour separation system for plastics recycling applications
Spektrum colour separation systems remove off-colours from a flow of plastic bulk materials. The material to be inspected is spread out on a conveyor and reaches the glass slide where the pieces are further individualised before continuing into the inspection area of the CCD linear camera. If an off-colour contaminant is detected its exact location is determined. Electronics evaluate this position and ejection nozzles are activated with pinpoint accuracy and at precisely the right time to blow out the contaminant. The ejection nozzles are so precise that the metal particles are removed with very little loss of good material and without any interruption to the material flow.

Colour Sorting Systems extract VA from shredder material and copper from brass and purify electronic scrap, pourable raw materials and initial materials of all kinds.
Steinert has been researching and developing separation techniques for many years. Practical experience has shown us the limitations of magnetic processes for particular separation activities, such as when bulk goods comprising several different materials must be separated out into their constituent elements, as is the case, for instance, in recycling. In such cases, certain constituent elements must be reclaimed and cleaned of any contamination to produce a perfect end product. Steinert has therefore developed the FSS colour sorting system. This can separate out from the material flow particular constituents that are visually different from the rest of the material. The relevant criteria are colour, brightness, granular size and shape. Our long experience in recycling guarantees that our colour sorting system also benefits from Steinerts usual high level of quality - in other words, robustness, long life and efficiency.
In the Steinert colour sorting system, a colour camera recognises distinct differences in colour, shape or size in the material to be separated. The material is compared on the built-in feeder conveyor and thinned out by a chute. After passing through the area covered by the in-line camera, the particles arrive at the ejection nozzles, which blow out the particles that are to be separated out.
