SPEKTRUM CE-G 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.
