Purifier Performer This Sesotec sorting system offers double-sided views of plastic flakes. In the process, plastic flakes are distributed via a vibrating conveyor chute and transferred to a slide that accelerates the material. While the flakes are in free fall, the system’s color cameras and hyperspectral near-infrared technology evaluate their material type and color; a metal detection bar removes ferrous and non-ferrous metals. The system sorts the materials into two fractions using short air blasts. Maximum capacity is about 2.2 tons per hour for the smallest machine and reaches nearly 10 tons per hour for the biggest machine, which is 10 feet wide.
What’s next? The Purifier Performer, unveiled at the K show.
Benefits High-throughput sorting of opaque flakes, including plastics covered with inks, labels, label adhesions or imprints; and adaptability of material detection. Also, the system offers flexibility with the sensors that are used, and users can retrofit it with different sensors.
