Comminution of ferroalloys

Ferro alloys are produced in solid blocks and crushed into smaller grain sizes for use in steel production. Due to their extreme hardness – for example in Ferrochrome, ferromanganese or ferronickel – wear-resistant grinding media are used. In the laboratory, mortars, sample mills, and ball mills utilize multi-stage processes (impact mill, ultrafine grinding < 100 µm). At the pilot plant level, combined systems (jaw crusher, roller crusher, impact mill) automate batches of up to 1 tons to achieve final finenesses of 50–XNUMX µm. For the extremely hard – such as ferrotitanium or ferrozirconium – special ceramic or carbide materials are often used as grinding media to minimize wear.
