Kenya Crushers For Iron Ore

Kenya Crushers For Iron Ore

Iron ore could be the fundamental waw material for iron & steel making.Of the total domestic consumption of iron ore, about 98% is accounted for by pig iron and stponge iron industries.Lumpy iron ore and agglomerates like sinter pellet from the feed for the production of pig iron in blast furnace,whereas stell scrap,lumpy iron ore ore pellet are the feed for sponge ireon production.

Kenya mining iron ore

Mining iron ore begins at ground level. Taconite is identified by diamond drilling core samples on a grid hundreds of feet into the earth. Taconite rock comprises about 28 percent iron; the rest is sand or silica. These samples are analyzed and categorized so that mining engineers can accurately develop a mine plan.Once the taconite rock is exposed, large drilling rigs drill blast holes 16" in diameter by 40' deep, in some cases. Nearly 400 of these holes are drilled in a blast pattern. Before the blast, the holes are filled with a special mixture of blasting agents.

crushing the ore

The crude taconite is delivered to large gyrator crushers, where chunks as large as five feet are reduced to six inches or less. More than 6,000 tons of taconite can be crushed in one hour.The crushed material is transferred by belt to an ore storage building, which holds up to 220,000 tons of taconite. An apron feeder sends the ore to the concentrator building for grinding, separating, and concentrating.

Kenya iron ore crusher processing

The processing of iron ore into raw materials that are ready to be processed into the material between the general uses of iron ore with iron content is high enough. In many countries of processed raw material is of primary iron ore with Fe content is quite high. In some countries such as India and China, raw materials used are low grade iron ore. This is done to solve the problem of expensive raw materials iron ore and iron ore reserve potential that exists.

One or two stages of crushing could be performed at the mine prior to shipping the raw material to the processing facility. Gyratory crushers are generally used for primary crushing, and cone crushers are used for secondary and tertiary fine crushing. Intermediate vibrating screens remove undersize material from the feed to the next crusher and allow for closed-circuit operation of the fine crushers. After crushing, the size of the material is further reduced by wet grinding in rod mills or ball mills. The rod and ball mills are also in closed circuit with classification systems such as cyclones. An alternative to crushing is to feed some coarse ores directly to wet or dry semiautogenous or autogenous grinding mills (using larger pieces of the ore to grind/mill the smaller pieces), then to pebble or ball mills. Ideally, the liberated particles of iron minerals and barren gangue should be removed from the grinding circuits as soon as they are formed, with larger particles returned for further grinding.
