Sensor based sorting 2014

More about the book

Hand picking is the oldest sorting method for purifying raw materials, but the demands of industrial processes have pushed manual sorting to its limits. The rapid development of data processing since the 1980s has enabled significant advancements in automated sorting, particularly benefiting the recycling industry through the recognition of material properties and pneumatic sorting of material streams. Multi-sensor technologies effectively address the challenges of identifying both low and high mass particles, as well as complex material compositions. While sensor-based sorting has thrived in recycling, its potential in the minerals industry is still emerging. The integration of traditional processing methods with sensor-based systems is paving the way for more applications in this sector. Sensor systems enhance human senses, delivering consistent results and extending perception into electromagnetic ranges beyond human capability. Innovations in the chemical, medical, and food industries have influenced the state-of-the-art sensor technologies in raw materials. The sixth expert conference on "Sensor-Based Sorting" explores new developments in automatic separation techniques for raw materials, focusing on systems that analyze feed material with sensors for selective discharge of components. Advances in sorting industrial minerals, metal ores, plastics, and more are discussed. However, limitations in current sensor technology h
