Denmark: A Tec upgrades calciners at Aalborg Portland Cement
09 March 2017


Two new calciners have been designed and delivered by A TEC to Cementir's Aalborg Portland cement plant at Rørdal during the annual kiln stop in February/March 2017. The project aims to increase the production of grey clinker by modifying the 4500tpd semi-dry kiln system which was originally commissioned in 1988.

A TEC will adapt the flow pattern of the calciner system to improve gas flow behaviour and operation of the system significantly. The design will be configured for the usage of 100 per cent SAF with the lowest possible emissions. Additionally, the number of kiln stops due fall through cyclone blockages will be reduced. A TEC is carrying out the detail engineering, supplies the equipment and is responsible for the erection and documentation.
