Caiman ore mining equipment manufacturer supply complete Iron ore mining equipment for Iron ore mining process

Iron Ore Processing Plant

Iron ore is the important mine ore, and plays an important role in our life. It also is an important iron and steel producers of raw materials, natural minerals (iron ore) after crushing, grinding, magnetic separation, flotation, gradually re-election and other procedures selected iron. In iron ore concentrator, crushing, screening and grinding machine is very important.

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.

Iron Ore crushing Machine

The primary crusher is Jaw crusher and Cone crusher. Our jaw crusher can reach the crushing ratio of 4-6 and the shape of final product is even. They are widely applied to crush high hardness, mid hardness and soft rocks and ores such as slag, construction materials, Iron ore, etc. The pressure resistance strength is under 200Mpa, that is, suitable for iron ore primary crush. It can be used in mining, metallurgical industry, construction, road and railway building, conversancy, chemistry, etc.

Iron ore grinding machine

Grinding is a powdering or pulverizing process using the rock mechanical forces of impaction, compression, shearing and attrition. Main machines in ore grinding process are ore mill equipment. The most common iron ore grinding mills in mining are ball mill, Raymond mill and high pressure suspension mill.

The belt conveyor and vibrating feeder used in Iron ore mining process

The crushed material is transferred by belt conveyor 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.

Concentrating

The crude taconite is now roughly the size of a football or smaller. A series of conveyor belts continuously feed the ore into ten large 27-foot-diameter, semi-autogenous primary grinding mills. Water is added at this point to transport it (94 percent of the water is recycled, while the rest is lost through evaporation).

Mixing with the Binding Agents

Once the filter cake is complete, it is deposited into a surge bin. It then travels onto a feeder belt and from there to a conveyor where bentonite, a bonding agent, is added. Bentonite is a clay from Wyoming used to help iron ore concentrate stick together when rolled into pellets. About 16 pounds of Bentonite are added to every ton of iron ore concentrate.

Pelletizing

A pellet plant contains a series of balling drums where the iron ore concentrate is formed into soft pellets, in much the same manner that one rolls a snowball, to make a pellet about the size of a marble (between 1/4″ and 1/2″). Pellets are screened to meet the size specification, with undersized or oversized pellets crushed and returned to the balling drums.

Pellet Loadout and Shipping

The pellets are now ready for shipping by train to customers or to ore docks. They are sent to blast furnaces and steel mills, where they will be turned into finished steel.

The selection of machine is according to customers’ requirements and the nature of the minerals.

According to the various sources of iron as well as certain economic and safety aspects in regards to its extraction is included, we provide you with a suitable iron ore mining equipment.
