Holcim’s GO4ZERO green cement project with Pfeiffer MVR mill technology
Gebr. Pfeiffer has received an order to supply a vertical roller mill of the type MVR 5000 R-4. The mill is intended for the new 4800 t/d kiln line of Holcim (Belgique) SA in the existing Obourg cement plant in Belgium.
Holcim (Belgique) SA has chosen Gebr. Pfeiffer‘s ultra-modern grinding technology for its GO4ZERO green cement project. A vertical roller mill of the type MVR 5000 R-4 will be used for cement raw material grinding. The mill will grind 370 t/h of cement raw material to a fineness of ≤ 15% R to 0.090 mm. At the same time, the cement raw material is dried in the mill from a feed moisture content of approx. 4% to a residual moisture content of < 0,7%.
In addition to efficient comminution and the associated high power density, MVR mills are also characterised by very smooth running and very low pressure drop. These features increase the technical availability and reduce both emissions and specific operating costs. In this project, the mill is integrated into the pioneering “oxyfuel operation”, with all the resulting requirements. This is, for example, the longest possible uninterrupted mill operation, to achieve the highest possible efficiency in the subsequent “CO2 capture process”.
This project is another example of how Gebr. Pfeiffer supports its customers in green cement projects to meet the current demands for CO2 reduction. The mill will be equipped with a latest-generation SLS 4000 VR classifier. Gebr. Pfeiffer is very pleased to be able to contribute again to reducing the carbon footprint. The contract is being handled by the Chinese general contractor CBMI. The MVR mill is expected to be put into service in the second half of 2025.
