100 % pellet inspection and sorting New dimensions in the inspection and sorting of material for the plastics industry
The purity of XLPE pellets as they are used for the insulation of medium, high, and extra-high voltages cables as well as for on- and offshore cables is a decisive characteristic for the quality of the end product. Damages caused by breakdowns due to contaminated material can easily run into the millions. Therefore, the production of highly clean material as well as the continuous detection and sorting out of contaminated pellets before they get into the extrusion process is of essential importance.
Unique combination of X-ray and optical technology
The PURITY SCANNER intelligently combines X-ray technology with an optical system. This allows the detection of metallic and organic impurities of 50 μm in the pellet itself and on its surface to 100%. Contaminated pellets are separated and sorted out in order to ensure that they do not get into the extrusion process. The application of both technologies is unique and is exceeding previous solutions on the market. Due to the specially developed X-ray technology, the PURITY SCANNER is the first system that inspects transparent and colored (e.g. black) pellets as well as semi-conductive XLPE material for impurities and sorts them out automatically.
Innovative Feeding System
The feeding of the pellets is carried out via a vibrating ramp. The material does not come into contact with the ambient air as the transport system is hermetically sealed. Absolute purity is guaranteed. The system is designed for a throughput of 500, 1,000 or 2,000 kg/h and can easily be integrated into existing feeding systems. With the new PURITY SCANNER, the quality and functionality of end products are improved significantly and, thus, the safety and usability for the end user are increased.
