Advanced, third generation sensors are used for metal and color separation, but the FLAKE PURIFIER is also equipped with a high-performance module to recognize other contaminants, including different types of plastic.
This innovative multi-spectrum sensor enables three simultaneous sorting functions. For difficult applications, the FLAKE PURIFIER combines information from each sensor to make highly precise sorting decisions.
Separation by Polymer Type
PET flakes can now be separated from PVC flakes and other organic material eg PLA, polyactide acid, (known to dramatically reduce the quality of recycled and even make high quality recycling not viable).
For basic sorting with distinct color contrast, high resolution greyscale sensors are an affordable solution. However, more demanding sorting, such as the separation of light blue and light green PET fractions, requires the use of real-color sensors, which effectively discriminate between similar colors with only small dissimilarities. To update from greyscale to real-color sensors is easily achieved with minimal modifications to the system.
Inductive sensors consistently detect metal particles as small as 0.6mm. Advanced microprocessor technology enables the FLAKE PURIFIER to identify the position of metal impurities precisely and effect separation with minimal material losses.
