VCS-A/B (13-25mm, 25-50mm) vertical separator is a new type of dry automatic coal preparation equipment based on advanced imaging and artificial intelligence technology. The dual-energy X-ray scanning imaging system is used to collect images of free-falling/chute-falling materials, and deep learning image recognition technology is used to analyze the images, determine the type of materials, and accurately control the high-pressure wind to spray gangue, impurities (or coal), To achieve accurate, efficient and energy-saving automatic coal sorting.
