Iron ore grinding mill & Grinding plants for Iron Ore

Iron exists in nature as a compound, and iron ore can be gradually selected after natural iron ore is crushed, milled, magnetically selected, flotation, and reselected. Therefore, iron ore is an important raw material in the field of steel production; generally iron ore grade less than 50% needs to go through the dressing before smelting and utilization.

Safe carriage of Iron ore & other iron concentrates in bulk

Mill Scale, a by product of hot rolled steel-making, is a bulk commodity liable to liquefaction, like iron ore fines. Mill Scale and Mill Scale Fines possess a transportable moisture limit (TML) and have thus been confirmed as Group A cargoes, which should not be accepted for loading without the shipper having certified the moisture content and TML.

Mill Scale – IspatGuru

The iron in the primary mill scale is usually present in different chemical forms. The primary scale has three layers of iron oxides consisting of wustite (mostly FeO), magnetite (Fe3O4), and hematite (Fe2O3) from the metal surface outwards. Wustite is the inner most phase of the scale which forms next to the metal and is the Fe rich phase.

Direct reduced iron

Process Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to drive off the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 C (2,190 F)).
