This paper will highlight the innovations associated with a new dry line which will substitute two (2) existing semidry lines for grey clinker production first started-up in the middle of the 1960s. Important reserves of high quality limestone guarantee long life for the new installation which is designed to fulfill both the present and future needs of a sustainable production — in particular related to the minimization of local environmental impacts and total energy consumption. The new line combines several innovative solutions, some of which have a limited number of installations (such as the installation of a roller press in the finishing configuration of the raw meal grinding installation) while some are entirely unique to the cement industry (such as the installation of a ceramic bag filter for the direct dedusting of the cooler vent air and the reuse of its hot, clean air for multiple energy recovery systems).
