MVR vertical roller mill for grinding calcined clay
Green cement for Holcim in the Czech Republic with the help of Gebr. Pfeiffer's MVR technology
One of the biggest challenges the cement industry is facing today is the reduction of carbon emissions in the cement production process. This can be achieved, for example, by substituting certain cement clinker components in the cement with SCMs. This drastically reduces the CO2 footprint of a cement plant, as the chemical process of burning cement clinker already releases large quantities of CO2, which are then saved.
This is precisely where Gebr. Pfeiffer supports its customers with its advanced grinding technology, as this is particularly suitable for grinding supplementary cementitious material. Gebr. Pfeiffer has received an order to supply an MVR 1800 C-4 vertical roller mill for grinding calcined clay to the existing Holcim cement plant Čížkovice in the Czech Republic, which will significantly reduce the proportion of clinker in the cement produced.
The highly efficient MVR grinding technology is characterised by extremely smooth running and high technical availability, even at the highest grinding fineness degrees, which is why it is perfectly suited for grinding such clinker substitutes.
This is one of the examples of how Gebr. Pfeiffer's technology is significantly supporting the cement industry on its path to decarbonisation.
The cements produced by Holcim Čížkovice with reduced clinker content and consistently high demands on product properties can therefore be described as "green cement".
The order to supply the mill was placed by the Chinese general contractor CBMI, which is also providing the technology for calcining the clay.
