Improving the Control of the Cement Making Process by ...

2017-12-17  The objective of this work is to improve the control of the cement making process by developing a fast and auto-matic multivariate method to calculate the amount of fer-rous iron of the calcium aluminate cement. Rapid deter-mination of the ratio Fe+3/Fe+2 provides useful information on the operating conditions of the kiln and improves the control of its atmospheric conditions. Therefore, the qua-lity of the final product can be improved.

Energy optimization in cement manufacturing

2021-2-16  Cement manufacturing is a complex and energy-intensive process. A key stage in this process is the conversion of ground raw materials (CaCO 3, clay and/or shale) into clinker (synthetic cementitious minerals) in the kiln. A typical operation uses kiln exhaust gases to preheat the raw materials before they enter the kiln. Further
