Sensor Based Sorting & Characterization
Sensor Based Sorting & Characterization lab
The MICA laboratory, began its activities by mineral characterization using optical microscopy digital imaging.
Its activities have expanded from characterization to sorting, controlling both the development of machine vision instruments, robotic sorting systems and pneumatic ejection systems, as well as complete industrial chains comprising sensors, PLC and grippers working in real time and at high speed.
Characterization remains the center of competence of the laboratory using the most advanced tools of this branch of artificial intelligence that is machine learning, starting from support vector machine to deep learning on GPU.
The studied materials were also diversified starting from traditional ore samples (crushed ore or drill cores) to recyclable materials. Last cases studies include battery sorting through 3D and XRT, metals alloys sorting using LIBS, sorting of plastics in PP, PE, PVC using SWIR, … but also flame retardant plastics using bromine.
An multi sensor industrial sorting bench, gathering on the one hand a conveyor belt rotating at speeds of 1 to 2 m / s, 3D scanner, hyperspectral VNIR and SWIR cameras , multi-energy X-ray linear sensor and an analytical LIBS scanner and on the other hand 5 delta robots and pneumatic ejectors.
Other instruments include hyperspectral core scanner, multispectral optical microscope, dry and wet powder size and shape analysis systems from 1µm to 1mm, 3D scanner for sand and aggregates…
Automated multispectral Imaging
An automated microscope with filterwheel allows registration and mosaicing of multispectral images of polished sections.
The main output is the modal analysis of the phases in the sample.
