Finnsementti has awarded Gebr. Pfeiffer with a contract to supply 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 mill amounts to 22 tph of 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 of 1.8 m dia., can be operated in two-roller-mode with approximately 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 to select the company’s mill. The plant design is compact, meeting expectations for fast maintenance actions. Finally, Finnsementti appreciated the broad range of services at the Gebr. Pfeiffer laboratory, starting from the determination of relevant grinding parameters via wear examinations up to reactivity tests.
The commissioning of the plant is scheduled for the late summer of 2020.
