Processing of electrosmelting slag in a ball-packed drum

The processing of steel-smelting slag involves discharge of the slag melt from the furnace, its transportation, cooling, and solidification, the extraction of large nonmetallic aggregations, crushing, sorting, magnetic separation, and storage of the final products. It requires energy-intensive equipment and special buildings: slag doors, gantries, pits, crushing and sorting systems, and stores, which occupy considerable space in the production buildings and require the attention of qualified staff. A much simpler approach is to process molten electrosmelting slag.
