Ciments Calcia commences Euro285m Airvault cement plant upgrade
17 October 2022France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO2 emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.
Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the project.
ThyssenKrupp to upgrade Ciments Calcia’s Airvault cement plant
07 December 2021France: Germany-based ThyssenKrupp has won a contract for the installation of a new 4000t/day clinker line at Ciments Calcia’s Airvault cement plant in Poitou-Charentes. The supplier expects the new line to double the plant’s clinker capacity while also reducing its CO2 emissions. It is intended to replace the two existing lines at the site.
ThyssenKrupp will supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 type vertical roller mill and a 10,000t tangential blending silo to process raw materials for the line. A single-string, five-stage Dopol type cyclone preheater with integral calciner will be supplied that is suitable to use with alternative fuels, with the possibility of conversion to oxyfuel in future. ThyssenKrupp plans to preassemble the preheater, reducing anticipated construction time ‘by several months.’ The plant also includes a Polytrack clinker cooler, a solid recovered fuel (SRF) preparation line and dedusting systems. Commissioning is scheduled for mid-2024.
No value for the project has been disclosed by Ciments Calcia or ThyssenKrupp. However, Ciments Calcia previously announced a proposed investment of Euro300m in January 2021.
