Crusher, A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.Energy Efficiency and CO Reduction in the Iron and Steel Industry, Energy Efficiency and CO2 Reduction in the Iron and Steel Industry SETIS In brief The iron and steel industry is one of the big - gest industrial emitters of CO 2, accounting for between 4 % and 7 % of anthropogenic CO 2 emissions globally. In the past 40 yearsFerroalloys, Today, almost all ferroalloys are produced in submerged arc furnaces (Fig. ), where raw materials (ores), reductants (coke, silicon-based ferroalloys, aluminum), iron additions (iron ore or steel scrap), and fluxes (lime, magnesia, dolomite, limestone, fluorspar, etc.) are loaded and smelted, followed by the tapping of slag and metal.energy saving iron crushers, Energy Saving Crushers For Scheelite In Oman. . is a iron ore machine manufacturer in China and supplies rock crushers and grinding mills for iron ore beneficiation plant.
