Machinery Technology Co., Ltd., Henan Rueiguang ball mill, energy saving ball mill www.hnruiguang.com, dry mill, wet ball mill, ball mill drum, high-energy ball mill, mixing mill, mining ball mill, rotary kiln, dryer www.rgdryer.com, industrial drying machine, dryer and other external heat processing equipment for your mining development to provide strong protection. I want to know more information, please call us 0371 -68,591,228 massive siderite in the rotary kiln temperature is higher than 800 ℃, the weak reducing atmosphere roasting, siderite into magnetite and hematite mixtures. By adjusting the temperature and the reduction potential of the atmosphere (CO / (CO + CO2) ratio) to adjust the content of magnetite in the calcine. Siderite kiln firing technology has the following characteristics: (1) the calcination temperature is greater than 800 ℃ (if less than 800 ℃, can not remain stable in the rotary kiln flame). (2) Use only lump ore. (3) for further combustion of coal and coal have special requirements, such as volatile matter, ash melting, bonding and so on. (4) huge investment, require complex, bulky transmission. (5) inefficient, small amount of processing. (6) high energy consumption, exhaust contains CO gas can not be recycled; calcination temperature is high, causing other carbonate decomposition. (7) operational difficulties, easy to knot ring (Xinjiang to build an annual processing capacity of 500,000 tons of kiln production line, has been not normal, regular and ring). Mechanical Technology Co., Ltd., Henan Rueiguang engineer in a rigorous scientific attitude, the spirit of seeking truth from facts for your mining development to provide scientific analysis, and prospects plan. For your ore for experimental analysis, investment analysis, profitability analysis, beneficiation process analysis, equipment selection analysis.
