The range of machines designed for simultaneous separation of metals and off-colour contaminants from the transported material by using combination of two techniques: the CCD optical camera system and selective metal detectors.
PRINCIPLE OF OPERATION
The material to be sorted is fed with a vibratory conveyor or belt conveyor (depending on the sorter type) to the inspection area consisting of the optical camera system and multi-segment metal detection coil. Any metal or off-colour contaminants are immediately detected and their location is determined. The signal is processed by the controller equipped with data evaluation electronics that activates the suitable nozzle of the integrated ejection system. As a result a contaminant is removed with very little loss of good material from the material stream.
APPLICATIONS
• removes off-colour contaminants and/or metals such as aluminium and lead from plastics (shredded PET, PVC and technical plastics) • separates cans and Tetra Pak containers from plastics • simultaneously separates metals and off-colour contaminants from glass cullet (flat glass, light bulb and fluorescent tube glass) • separates aluminium and plastics from wood chips • sorts out metals of similar colour (separation of copper from brass, and aluminium from grey metals)
ADVANTAGES
• simultaneous evaluation of different types of metal • electronic metal detection sensitivity adjustment • evaluation of the entire visible light spectrum • high-speed valves of ejection nozzles • modular design
