Comex AS delivers innovative and cost-effective solutions for processing, sorting and refining of a variety of materials. We deliver sustainable and environmentally friendly solutions for the improvement of processes in the mining, recycling and material processing industries. The core activities are related to the technologies for production and classification of fine powders and sensor based sorting of large particles. Comex' efforts and accomplishments in R&D result in the latest state-of-the-art equipment together with know-how for industrial process solutions. Sorting technologies. Comex has developed a new optical sorting system based on a complex image analysis. The system separates materials by recognition of many different properties in the same unit: color, shape, size, surface texture, density, transparency, X-Ray transmission and X-Ray fluorescence, thermal transfer, conductivity, electromagnetic induction. It provides an efficient mineral purification before grinding. The same system can be used for both material sorting and identification or characterization without necessary separation. Powder technologies. Comex offers equipment for production and classification of fine particles that incorporate unique world patented air classifiers and jet mills providing powdered materials in size from 300 to 2 microns. These materials are very widely used today for different applications like: fillers, pigments, coatings, medical products etc. In addition to the newly developed equipment, the complete solutions for fine particle production include other necessary elements as: grinding mills, dust collectors, automatic control and monitoring systems. On-line analyzers. Comex offers equipment for on-line particle size analysis which can be used in laboratory scale or on-line in the production process. It includes multi-channel on-line particle size distribution analyzers working in wet and dry modes.
