Finnsementti (CRH group) has awarded Gebr Pfeiffer a contract for the supply of a MVR 1800 C-4 slag grinding mill type. The new slag grinding plant will be built next to a steel works in Finland.

Gebr Pfeiffer will supply 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. The German equipment supplier will also be responsible for the plant design and process engineering.

The MVR 1800 C-4 has a grinding capacity of 22tph 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 1.8m is a proven mill type and can also be operated in two-roller-mode with approximately 60 per cent of its maximum capacity during maintenance, claims Gebr Pfeiffer.

The commissioning of the plant is scheduled for the late summer of 2020.
