improves quality control at the Hereke cement plant in Turkey

While near-infrared (NIR) analysis is an established technology for the analysis of raw materials and raw meal in the cement plant, it is now being used as an online analysis system for SO3 and clinker phases at Nuh Çimento’s finish mill in Hereke, Turkey.
