12.5.1.2 Iron Production - Iron is produced in blast furnaces by the reduction of iron bearing materials with a hot gas. The large, refractory lined furnace is charged through its top with iron as ore, pellets, and/or sinter; flux as limestone, dolomite, and sinter; and coke for fuel. Iron oxides, coke and fluxes react with the
5.1. A primary gyratory crusher was required to crush iron ore at the rate of 3000 t/h. The largest size of the run-of-mine ore was 1000 mm. The required product size was less than 162 mm. Manufacturer's data indicated that the nearest size of gyratory crusher would be 1370 mm × 1880 mm with a cone angle of 18°.

The raw material is processed further in a secondary crusher after being first crushed by a first crusher. The main crusher reduces bigger rocks or boulders into smaller, easier-to-handle fragments. Secondary crushing is used to further reduce the material's size and get it ready for additional processing steps.
The role of the secondary crushing circuit, like every other stage in mineral processing flowsheets, is to prepare the feed material for the next stage of the process. The …
Hematite and magnetite are the most prominent iron ores. Most of the high-grade hematite iron ores (direct shipping ore (DSO)) are subjected to simple dry processes of beneficiation to meet size requirements. This involves multistage crushing and screening to obtain lump (− 31.5 + 6.3 mm) and fines (approximately − 6.3 mm) products.

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
output of secondary crusher becomes feed for grinding process in common way. Thus, the size of feed for grinding o r milling stays in the range o f 5 - 250 mm (Wills, 2006).
Innovation has an important role in improving the productivity, safety and sustainability of mining operations. Historically, ore transport was done by diesel trucks, but with the commitment to reduce CO2 emissions and increase mine safety, mining companies have invested in innovative, more sustainable ore transport technologies. The innovative …

Their machines are designed to handle a wide variety of materials and are suitable for use in different …
Rock Crusher History. History tells us, it was in 1830, the first US patent was issued on a rock crushing machine. It covered a device which, in a crude way, incorporated the drop hammer principle later used in the famous stamp mill, whose history is so intimately linked with that of the golden age of mining. In 1840, another patent was …
The fines from the grizzly and the crusher discharge pass by gravity and/or conveyor to a Combination Scrubber and Trommel. Here, further scrubbing and washing takes place to separate the ore into two fractions, usually plus and minus ½ inch. The coarse washed fraction is further reduced in a Secondary Cone Crusher without difficulty.
Secondary crushing, as you can imagine, is the second stage of material processing following its initial reduction. At this stage, material will flow through perhaps a second impactor or even a cone crusher, which is effective at breaking down these types of material. There are also tertiary and even quaternary stages of crushing that exist to ...
Secondary crushing (or intermediate crushing) accepts the material from the primary crushing stage and reduces it even further, whether for final product sizing or in preparation for final product sizing in …

The third step in crushing, or tertiary reduction, depends upon what is required. Two-inch or smaller pieces from the secondary crushers may be fed direct to stamps, rod mills, or ball mills, but it is more usual to use a third dry crusher to reduce the ore to ½- or 5/8-in. size before wet crushing, particularly in the case of ball milling.
