C/CLAY: the Greenkey to clay calcination and grinding

High clinker substitution rates and worldwide abundance make calcined clays the next generation of supplementary cementitious materials (SCMs). The key to exploit their potential lies in careful process design and the selection of equipment suitable for both greenfield plants and kiln retrofit projects. With their C /C L AY  toolkit, Loesche and Dynamis take a technology-independent approach that offers solutions for kiln and flash calcination and includes process upgrades to maximise the capacity of existing lines.

Calcined clays represent the next generation of supplementary cementitious materials (SCMs). This is not just a sketchy outlook but can be deduced from the yearly increasing number of industrial projects worldwide that seek to leverage their benefits. Calcined clays possess several properties that can be utilised in cement production to reduce carbon emissions. Due to their abundance, they can be employed instead of increasingly scarce materials such as fly ash and slag. In the case of the LC3 mix, they achieve optimal synergy effects when combined with limestone, thereby expanding the range of clinker substitute materials.
