From process control to quality prediction:
Artificial intelligence in clinkering process control
Cement production is a complex process from blending various natural and synthetic materials through a high temperature process to clinker and cement. The cement industry took off into a digitized future probably a decade ago. Today there are various tools to compile data from sources and detectors in the plant and transfer numeric data to automated procedures for analyses and identification of factors to improve energy management and maintaining quality of the final products. A new important tool will be automated isothermal calorimetry (polabCal) to assess clinker and cement reactivity online. [Photo: Authors/tkIS]
