Air-swept mill Air-swept mills with one grinding compartment are used for the combined grinding and drying of very moist materials because large quantities of low-temperature gas can be passed through its drying chamber. This mill can accept ores up to a lump size of 15 mm (in special cases up to 30 mm) and a moisture content of up to 15 %.
What exactly is Mill Scale and what is done about it
2005. A. Mill scale consists primarily of magnetite, Fe 3 O 4, of characteristic blue-gray "steely" color. An extremely thin outer film of hematite, Fe 2 O 3, is invisible to the naked eye. The inner portion of the magnetite contains fine metal grains and sometimes, residual black FeO (see below), which contribute to the roughness of descaled metal.
