Recently, the Finnish cement company Finnsementti awarded Gebr. Pfeiffer with a contract for the supply of a slag grinding mill type MVR 1800 C-4. The new slag grinding plant will be built next to a steel works in Finland. The order comprises the supply of the complete equipment from the slag dosing and conveying system to the outlet of the process filter including the hot gas generator, process fans and all main motors. Furthermore, Gebr. Pfeiffer is responsible for the plant design and process engineering.

The throughput of the Gebr. Pfeiffer mill type MVR 1800 C-4 amounts to 22 t/h slag powder (dry-base), depending on the product fineness with up to 5000 Blaine. The mill with four equal-sized grinding rollers and a table diameter of 1.8 m is a proven mill type and can also be operated in two-roller-mode with approx. 60 % of its maximum capacity during maintenance.

Gebr. Pfeiffer’s expertise and references in the field of medium-scale cement and slag grinding vertical roller mills convinced Finnsementti, amongst other advantages, to select the Gebr.

Finally, Finnsementti appreciated the broad range of services at the Gebr.
