Abstract

In Kaspi cement plant (Heidelbergcement group) the new 5 stage pre-calciner kiln (3000 TPD) was erected in 2016 and commissioned in 2018. It was a brownfield project, the existing wet plant was stopped with 3 long wet kilns, only cement grinding mills remain in operation. It is quite common thing to upgrade old process equipment with new installations but in this case source of main material, limestone was also changed, it was quite challenging.
My PHD work is related to the new production process and control concepts which were necessary to implement for keeping high production, low power and heat consumption and most importantly excellent quality to build the future.
