MVR vertical roller mill for slag grinding

Slag grinding with Gebr. Pfeiffer mill in Sweden

Gebr. Pfeiffer has been awarded a contract for the supply and construction of a complete granulated blast-furnace slag (GBFS) grinding plant with a Gebr. Pfeiffer mill type MVR 2500 C-4. The plant is in Oxelösund, located on the eastern coast of southern Sweden.

The new business partner is Swecem AB, part of the Peab corporate group, one of northern Europe’s leading construction companies. Swecem AB operates in the field of cementitious materials for concrete production and intends to produce its own environmentally friendly cement.

The contract includes the supply and installation from the top of the foundation up. It comprises the complete process equipment, electrical equipment and automation system as well as the complete building on EPC basis.

The throughput of the Gebr. Pfeiffer mill type MVR 2500 C-4 with its four equal-sized grinding rollers and a table diameter of 2.5 m amounts to 25 t/h slag powder (dry-base). The mill is driven by an electric motor with 750 kW.

The start of operation is planned for the spring of 2020.

“The success of having sold numerous MVR mills for cement and slag grinding and the experience gained in the field of medium-scale cement and slag grinding vertical roller mills were decisive reasons for Swecem AB to select Gebr. Pfeiffer’s proven vertical roller mill. This order once again demonstrates Gebr. Pfeiffer’s capabilities and competences of delivering full scope systems. Furthermore, Gebr. Pfeiffer’s core competence in grinding technology and corresponding services are constantly being improved and further developed. In this instance, Gebr. Pfeiffer offers a service agreement, starting from mechanical inspection via process optimization up to replacement of main wear parts.” says Ludwig Zetterström, CEO Swecem AB.
