Sinter Base Blending System. This circuit comprises of the raw material preparation and handling system for feeding raw materials from stock yards to sinter plants SP2 and SP3, conveying product sinter to the blast furnace stock house, coke and lump ore to blast furnace stock house and handling coke/sinter fines generated in stock house.
Bulk raw materials handling plant and sintering plant preparatory plants are established to receive, blend, stockpile, prepare and supply specified grades of raw materials for smooth operations of iron making plant (Blast furnace), steel making plant Influence of limestone particle size on iron ore sinter properties and productivity. 2010
Under the longterm interaction between coalbearing strata and groundwater, particularly in highsulfur coal mining areas with large amounts of hematite and pyrite exposed, acid mine drainage (AMD) is easily formed, as shown in Fig. 1 [3], [4].Acid mine water contains sulfuric acid, Fe 2+, Fe 3+, Mn 2+, etc., may also be enriched with some traces of toxic
Lime Component Limestone: Common forms of calcium carbonate used as raw material for cement manufacturing are limestone and chalk.Limestone is of predominantly fine grained crystalline structure, its hardness is between 1.8 to 3.0 of the Mohs scale of hardness and specific gravity 2. To 2.8. Limestone usually contains admixtures of clay substance or

sintering machine. Other raw materials may be added, including iron, silica, limestone flux, coke, soda, ash, pyrite, zinc, caustic, and particulates gathered from pollution control devices. The sintering feed, along with coke, is fed into a blast furnace for reducing, where the carbon also acts as a fuel and smelts the leadcontaining materials.
