1, continuous production, short cycle, yield, high quality. 2, countercurrent principle work, therefore, high thermal efficiency, fuel economy, because the use of heat retention and heat very well, so it saves fuel. 3, the firing time is shorter, the more common large kiln from the kiln fitted to the air takes 3-5 days, and tunnel kiln, there was about 20 hours to complete. 1, continuous production, short cycle, yield, high quality. 2, countercurrent principle work, therefore, high thermal efficiency, fuel economy, because the use of heat retention and heat very well, so it saves fuel. The impact of impurities in chemical composition of limestone ore, in addition to containing the active ingredient than CaCO3, lime kiln offer, but also contains a variety of harmful impurities. There are three main ways to impurity sources: (1) self-contained mineral impurities, such as: SiO2, Al2O3, Fe2O3, K2O, Na2O, P, S and the like. (2) ore in the mining process, ore wall rock or mezzanine mixed impurities. (3) ore in mining, transportation, loading and unloading, ore adhered to the surface of the soil, sand and other impurities. No matter where it comes from impurities, will be on the lime kiln to produce great harm. Calcium-containing compounds such as impurities in the SiO2, Al2O3, Fe2O3, and began firing in lime CaO occurs at a lower temperature (900 ℃) reaction, in the firing zone is easy to form a liquid phase, with a low melting point adhesive, such as silicon limestone (CaO · SiO2), dicalcium silicate (2CaO · SiO3), iron and calcium (CaO · Fe2O3 and 2CaO · Fe2O3), etc., lime kiln, with increasing reaction temperature. These low-melting compounds generated, resulting in mutual bond between the lime particles clogging the particle surface pores, not only reduces the activity of the lime, can also block the escape of CO2 decomposition pathways, lime kiln, so that incomplete decomposition of limestone, lime kiln advanced equipment calcined lime with "core, forming a green burnt lime, resulting lime activity decreased, affecting its quality. When the impurity content is too high, and lime CaO reaction after the formation of agglomerates kiln tumor, causing the furnace operation disorder. When SiO2, Al2O3 Fe2O3 and total or Na2O, K2O is at least 4 to 5%, or 0.1 to 0.2%, respectively, is easy to cause harm to furnace conditions. lime kiln factory, blue sky kilns, lime kilns by the Linyi City Luozhuang Blue Sky kiln Limited.
