Severstal has begun installing the world’s largest dry-grinding ball mills at its new iron ore pellet production complex in Cherepovets. The mills, each measuring 6.7 meters in diameter and over 13 meters in length, will support the facility’s planned capacity of 10 mln tons of pellets per year.
Alongside the ball mills, work continues on roasting machines, pelletizers, vertical mills, and auxiliary infrastructure, with over 30pct of the metal structures already in place. Raw material conveyors are also being modernized.
The project will enable Severstal to replace its existing sintering facilities with cleaner, more sustainable pelletizing technology. Three sintering machines at CherMK were shut down in 2024 under the federal Clean Air program, with the remaining four to be decommissioned in early 2027 once the new plant becomes fully operational.
Scheduled for launch in the second half of 2026, the complex marks a key step in Severstal’s environmental transition.
