MILL SCALE SEPARATION - Nordic Water

MILL SCALE SEPARATION FEWER FILTERS AND LOWER COSTS Mill scale forms during steel production. It is a thin oxide coating that is created when steel is hot-rolled. When the steel is cooled down with water during the rolling process, the mill scale breaks off. The cooling water is re-used over and over again, which means that mill scale and oil

Mill scale separation – Nordic Water

The mill scale contents processed often amount to a full 400 mg/l. This process is also relatively insensitive to oil emulsions and has proved to be very effective at separating them too. A lamella can be used to take care of the wash water from the DynaSand system, or a Sala thickener with a rate of 2 m/h.

Mar 01, 2021  The main impurities in the manganese ore and mill scale are CaO, MgO, Al 2 O 3, and SiO 2. Before roasting, all the raw materials were crushed, ground, and screened to 100 wt% by being passed through a 0.074-mm mesh in advance. The average particle sizes of the mill scale and manganese ore powders are 29.4 μm and 24.2 μm, respectively.

Mill scale is the by-product of iron and steel industry. It can be recycled via sinter plant or solid as sinter feed materials. 85 to 90% of the constituent particles are more than 0.008 inches. The iron content is near around 70 %, with a very small amount of alkaline compounds and non-ferrous metals. Mill scale is polluted and contaminated with lubricants, oils and greases from the equipment.
