Refractory iron ore belongs to poor fine miscellaneous ores with complex composition, there is a lot of difficulty to improve ore grade by traditional dressing recovery way, while grinding fineness is a key factor. For example, Qidong iron ore asks grinding fineness -38 um 95% ~ 98%, Shanxi Yuanjiacun iron ore asks -38 um 95%, as well as Shizhuyuan solid non-ferrous metal ore and Ruyang molybdenum mine ask grinding fineness in tailings recovery - 38um 95%. Therefore, regrinding or fine grinding equipment is essential. Many of our mining industry produce iron ore by ordinary horizontal ball mill, while the ordinary horizontal ball mill has low efficiency, the product particle size and mineral monomer dissociation cannot reach requirement.Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite, hematite , goethite, limonite or siderite. Ores carrying very high quantities of hematite or magnetite (greater than ~60% iron) are known as "natural ore" or "direct shipping ore", meaning they can be fed directly into iron-making blast furnaces. Most reserves of such ore have now been depleted. Iron ore is the raw material used to make pig iron, which is one of the main raw materials to make steel. 98% of the mined iron ore is used to make steel. Indeed, it has been argued that iron ore is "more integral to the global economy than any other commodity, except perhaps oil".
Energy-saving measures for new dryer: (1) Transform the dryer tail at low temperature drying at about 1/3 of the L-shaped lifting plate. Generally, L-shaped lifting plate is vertical fixed in 90 , and the plates around can be welded in 30 , 90 , 120 angle respectively; Thus, the spreading area enlarges by industrial dryer rotating. Consequently, the heat exchange rate is higher; Be noted that the transformation of the industrial dryer should consider comprehensively. If the ventilation is good, the exhaust gas temperature is over 100 C, we can add a few X-shaped center sets. On the contrary, if poor ventilation, the exhaust gas temperature is below 70 C, we need to reduce groups of the X-shaped lifting plate center; It is very important to control exhaust gas temperature. When temperature is too high, on the one hand, it will cause high energy consumption, on the other hand it will burn the dust bag; The other way around, it will cause a bag paste, which affects ventilation, and makes production decline, severe dust internal component corrosion and high maintenance costs.
After our introduction, our customers will not have big problems and troubles in the operation and maintenance of dryer machine. It will also increase the relative safety factor of dryer, save the cost and guarantee the safety production.
