New Era of Cement Production

Integration of new technologies with sustainability goals and environmental protection initiatives is essential for addressing global challenges. Here at Rieter Morando we stand for continued innovation and collaboration across sectors for a more sustainable and resilient future. That is why cement producers choose us as a preferred supplier of a clay treatment machinery for the pre-calcination stage.

SUPPLEMENTARY CEMENTITIOUS MATERIAL (SCM)

Using clay as an SCM in cement production is a sustainable approach that can help reduce carbon emissions and minimize the environmental impact of concrete. By incorporating clay as an SCM in cement manufacturing, producers can not only improve the performance and durability of concrete but also contribute to environmental conservation efforts by reducing carbon emissions and conserving natural resources.

LC3 - A low-carbon alternative

Limestone Calcinated Clay Cement (LC3) is a new low-carbon blended cement that allows cement manufacturers to reduce the CO2 emissions from production. Funding from the Swiss Agency for development and cooperation (SDC) helped bring the LC3 technology from the lab to large-scale commercial production. The SDC supported the development of the scientific basis for LC3 and the testing of production, and is promoting the adoption of LC3 standards and supporting global outreach.

Starting from the clay quarry, Rieter Morando offers different types of machines depending on the characteristics of the material. The photo shows a crusher installed directly in the quarry on a mobile platform to reduce the most manageable block sizes up to 1 meter.

Here is an example of a project we implemented in 2023 for a cement industry. With the scope of CO2 emission reduction, our client began to use clay as a supplementary cement material. We designed a clay pre-treatment line together with the client based on characteristics of a raw material. Coming from a primary crusher the clay is treated and extruded to meet required characteristics for the subsequent calcination process.
