Brief description of iron ore crushing and grinding mill and beneficiation process flow

Iron ore belongs to the important smelting raw materials, from the first half of the market development market, although the development of the state has improved significantly, but the second half of the metallurgical raw materials market is facing more contradictions, for the iron and steel industry is a challenge but also an opportunity, so this requires both from the iron ore mining to crushing and grinding, and then smelting and processing both the quality of the pursuit of the method to pay attention to the strategy of the development of the iron and steel industry by raw materials, environmental protection requirements, The development of the iron and steel industry by raw materials, environmental requirements, market conditions, government decision-making and other uncertainties, the development of suffering but there are opportunities everywhere.

Processing equipment: vibrating feeder, jaw crusher, cone crusher, vibrating screen, ball mill, spiral classifier, magnetic separator, dryer and so on.

Crushing and screening: Because of the hardness of iron ore, the choice of crushing equipment is also slightly required, large iron ore can be sent to the jaw crusher by the vibrating feeder for coarse crushing, the right size of the material pieces and then sent to the cone crusher for secondary crushing, by the cone crusher crushing the fineness of the material can reach 0-12mm, after the vibrating sieve mountain screened to be the next step of the milling process grinding.

Grinding: Iron ore mill selection is mostly based on the ball mill, the upper level of crushed materials evenly and orderly sent to the ball mill crushing, and then screened by the spiral classifier, qualified materials excluded, unqualified materials back to the grinding room to regrind.

Note: here have to deliberately emphasize, iron ore mill choose ball mill is appropriate, Raymond mill, high pressure mill, European version of the mill, although it can also be crushed, but from the demand for finished products, production, the next level of auxiliary selection and other process considerations, the ball mill is the most appropriate, in the majority of mills instructions are also clearly stated, Raymond mill vertical structure with the help of grinding rollers and grinding ring grinding equipment, is not a metallic minerals, flammable and explosive ores. The crushing.

Magnetic separation process: Because of the more impurities in the iron ore, it is necessary to remove impurities, magnetic separator can effectively remove impurities, to protect the quality of the finished product.

Precautions: iron ore impurities within a variety of complex removal, and some magazines for harmful impurities, not only will destroy the iron ore itself, but also seriously affect the late use of iron and steel products performance, such as sulfur, phosphorus, arsenic, potassium, sodium, fluorine, phosphorus in iron ore smelting is easy to rupture, the occurrence of cold embrittlement, there are a number of manganese, nickel, chromium, vanadium, titanium, etc. belongs to the beneficial elements, and to a certain extent, to improve the performance of the finished product.

Drying treatment: drying treatment is the final process of iron ore processing, drying iron powder can get high quality iron powder.

Ironmaking process has a long history of development in China, and steel is a necessary raw material for production and life.
