The impact of impurities in chemical composition of limestone ore, in addition to containing the active ingredient than CaCO3, buy green lime kiln, 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., with increasing reaction temperature. These low-melting compound after generation, 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, so that incomplete decomposition of limestone, lime firing zone "core , forming a green burnt lime, resulting lime activity decreased, affecting its quality. When the impurity content is too high, and after the reaction, CaO lime kiln tumor mass formation, resulting in furnace operation disorder. When SiO2, Al2O3 and Fe2O3 or Na2O , respectively, when the total amount of K2O more than 4 to 5%, or 0.1 to 0.2%, easily cause harm to the furnace conditions cloth system: system consists of cloth material cup, fabric composed of material cup timer switch door, four cloth distributor a peripheral, so that even fabric ash system: ash system consists of a gray turntable, star of the gray machine and a gray belt composed of small green lime kiln, in order to start, reverse stop, to protect the ash smooth temperature measurement. systems; temperature measurement system consists of 11 high precision measurements accurate thermocouple measurement accuracy of 0.01 degrees Celsius temperature to ensure the accuracy of .1 blowing and the wind blowing and the wind system, the system has a blower, blowing converter. and induced draft fan, the wind frequency converters, environmental protection lime kiln, according to the size of the blast pressure and the wind pressure to adjust the frequency converter and the wind blowing converter 2, the control system; control system by the German Siemens original Imported PLC computer control system, display system using Purple golden bridge configuration software displays real-time data, and record keeping.
