Iron ore crushing machine: introduction of the iron ore Iron ore is an important raw material of steel producers, iron ore after crushing, grinding, magnetic separation, flotation, re-election and other procedures select of iron. Iron ore is economies of iron or iron compounds containing mineral aggregates. Common iron ores are magnetite, hematite, limonite, siderite, and other pyrite, blue iron ore. The first four types are usually used to make iron and pyrite is mainly used for production of sulfuric acid and sulfur extraction, with the production of iron , while the blue iron is one of the world's most famous gems, easily oxidized in air, is a very precious materials. Introduction of various iron ore Magnetite: mainly Fe3O4, is the highest grade of iron ore. Hematite: the main component of iron oxide, i.e. Fe2O3.Also has the high grade. Siderite: low grade, ferrous carbonate. Blue Iron: hydrated iron phosphate. Pyrite: FeS2 , sulfur content is high. How to choose the iron ore crusher Iron ore crushing and grinding machines, mainly include primary crushing, middle crushing, grinding equipment, jaw crusher is the most common primary mineral processing equipment, PE1200 * 1500, PE1000 * 1200, PE900 * 1000, PE600 * 900 are widely used mining equipment, according to different yield, you must make a reasonable choice(our sales manager will based on years of experience give you useful suggestions).Jaw crusher is the main design of simple structure, easy to understand the principle, easy maintenance, large feed opening, the cost is low, very suitable for crushing operations. It is very popular. Cone crusher is usually used for medium and finely crushing, generally in the crushing of iron ore will be divided into two crush stages, mainly the medium broken section, you can take the standard type cone crusher which has large feed opening, the output size of material is in 20mm or more, in the finely crushing process can use the short head type cone crusher, fineness of output can be well controlled, reaches 13mm or less, the minimum output size currently can reach is 6mm.
