Airvault cement plant modernisation.

Location
France.

Project Owner/s
Ciments Calcia, subsidiary of HeidelbergCement Group.

Project Description
The project involves the construction of a turnkey cement production line.

The line, with a production capacity of 4 000 t/d of clinker, is to be built at the Airvault site to replace the two existing lines.

The project will almost double clinker production at the Airvault site.

The plant is designed to allow for conversion to oxyfuel technology in the future to efficiently separate carbon dioxide and, thereby, facilitate carbon capture and storage at a later stage.

Equipment for the raw material preparation includes a double-shaft hammer crusher with a capacity of 1 200 t/h, a longitudinal blending bed, a vertical roller mill with a throughput of 370 t/h and a tangential blending silo
with a storage capacity of 10 000 t for the raw meal.

The kiln line comprises one string, a five-stage cyclone preheater with integral calciner suitable for using alternative fuels and a three-support rotary kiln, followed by a clinker cooler.

The plant also includes a preparation workshop for alternative fuels (solid recovered fuels) and proven and reliable dedusting systems.
