Automated cement plant quality control

Increasing production and quality demands in the cement industry have resulted in the need for improvement in the speed and accuracy of quality-control results. This need has been addressed many technological advances in quality-control automation in recent years. Two distinct methods of sampling and analysis, in-situ and extractive, have gradually developed. In-situ analysis occurs in the field at the process equipment, with the results transmitted through a computer control system. This article discusses the characteristics and differences in analyzer and control technologies that utilize the two different methods of obtaining a result.
