SIKORA's PURITY SCANNER ADVANCED inspects 100 % of plastic pellets online and automatically sorts out contaminated individual pellets from 25 µm upwards. The system combines X-ray technology with a flexible optical system. In addition to the X-ray camera, up to three cameras can be installed depending on the expected contamination and application. All types of pellets are reliably inspected. The X-ray camera detects metallic impurities in the pellet and on its surface. Color deviations in transparent or on translucent and colored raw materials are detected by the optical cameras. Contamination are automatically sorted out, thus ensuring material quality.
