The mill scale is a waste from the iron and steel industry. Due to the high content of iron in the form of oxides, it is an attractive material for the recovery of metallic iron by reduction. The product of mill scale reduction is an iron with a very extended surface and a high affinity for oxygen. The smaller iron particles are, the easier it is for spontaneous rapid oxidation, which can be ...

In the handling of wet, sticky ores such as encountered in tropical areas having distinct dry and rainy seasons, the crushing plant is a section of the mill which must be planned very carefully. Unless this is done, crushing becomes a constant source of trouble resulting in lost production and high milling cost. In some areas rainfall is high for prolonged periods.

Mill scale is a thin layer of iron oxide that forms on the surface of structural steel when it's exposed to oxygen and moisture. You can remove mill scale with a variety of methods, including sandblasting, pickling, grinding, and chemical stripping. Sandblasting is the most common method for removing mill scale from steel.
