subject: Spiral Classifier Is Used For Purification [print this page] Spiral classifier.html">classifier is refining equipment, it is mainly used for the classification of some ores, purification of the above, common equipment vibrating feeder, belt conveyor, and other iron ore beneficiation equipment.
Why do I need to iron "purification," This is mainly because the pig iron is more brittle, little flexibility, is not easy to machining, casting, not welded, it is mainly used for less demanding of the machine bed, casing, base, wok. The steel has good toughness, plasticity, weld ability, which can be calcined to play, rolling, spinning, ease of machining, wide range of uses. Since the pig iron and steel formula is Fe, why they have such a huge difference? The original pig iron, high carbon content, and contains the right amount of impurities such as silicon (Si), manganese (Mn), sulfur (S), often called the carbon content higher than 2% of pig iron, carbon content in the identify 03 to 29 is steel, called wrought iron below 0.03%. Well, in fact, the steelmaking process is to reduce the carbon content of pig iron, and the process to remove the right amount of impurities. Of workers and often this process is briefly summarized as follows: lowering carbon, transfer of manganese, to parathion.
In everyday life, steel has become a use of the most common demand to be called champion of the metal, a huge machine tools, agricultural machinery, automobiles, trains, ocean liners, heavy tanks, as well as stationery, iron pots, pens need iron and steel to cast. Steel is an iron and steel, collectively, First of iron ore after smelting in the blast furnace pig iron, pig iron and then into the steelmaking furnace by tempered only steel. Steel is how change is made? First mining a wide variety of iron ore, these are hematite, magnetite, limonite, and siderite etc. The most commonly used are hematite (including Fe2O3) and magnetite (Fe3O4). Of iron in iron is a compound form, how to get the elemental iron? In ancient China, the earliest iron smelting is with the help of charcoal and ore role, but it is inefficient. Open a furnace iron fireman, burning charcoal workers more than a thousand.
Purification such as hematite are the focus of attention, spiral classifier, magnetic separator, and mineral processing equipment containing iron ore has been highly efficient purification these ore for ore pre-grading work is indispensable for the necessary equipment, such as hematite ore purification process.
