Title Ten drying expertise of copper focus dryer device
Description Construction Waste Crusher would be the particular device utilised for drying widespread steel ores; it has the benefits of large drying effectiveness, quick velocity, and strong ongoing procedure potential. Its drying outcome is remarkable for that business ores including copper concentrate, hematite, and so on. Copper is among earliest metals that be found and utilised by human beings, it really is aubergine, with the specific gravity of 8.89, and melting point of 1083.4℃. Copper and its alloy are extensively utilized due to its good electrical conductivity and warmth conductivity, powerful resistance to corrosion, easy processing, favorable tensile energy and fatigue resistance. It ranks only 2nd to steel and aluminum in metal materials intake, and become the obbligato base material and strategic provides of nationwide financial system, people’s livelihood, defense engineering and even advanced technology. It's got commonly applications in the industries of electric powered, machinery, chemical, defense engineering, and and so forth. copper concentrate could be the focus that processed by the low grade copper contained raw ore, it can be used to smelt copper directly. At present, the raw materials to refine copper in China mainly are towanite, chalcocite, bornite, malachite and etc. According to the technical conditions of smelting, the copper ore can be divided into three classes based on the proportion of copper oxide and copper sulphide, that is, sulfide ore, which contains less than 10% copper oxide;oxidized ore, which contains more than 30% copper oxide; mixed ore, which contains 10%~30% copper oxide. Raw materials of copper ore have the following characteristics: 1) raw materials of copper ore that suitable for smelting are stored in multiple deposit types. Among them, the deposit types of important exploitation values are magma copper nickel sulfide deposit, porphyry copper ore deposit, skarn type copper and polymetallic deposit, Hydrothermal vein copper deposits, Volcanic sedimentary sulfide copper deposits, and Depositional layered ore deposits and etc. 2) The ores are complex ore structures, unevenness disseminated granularity, nonuniform disseminated, mineral assemblage, subtle fabric disseminate, complex composition, and different to dress. 3) Ore chemical compositions are complex, accompanying and inter growing with many beneficial and harmful component, so, its smelting process conditions are very complex.
