Lime deep processing: linking calcium method. Calcium chloride solution was treated with hydrochloric acid to give slaked lime, calcium chloride solution was carbonized after inhaling ammonia precipitation of calcium carbonate with carbon dioxide will be obtained. Lime Quality: The lime produced cementitious ingredients are effective calcium oxide and magnesium oxide, its content is the main indicator of the quality assessment of limestone. Lime: limestone particle size. Limestone particle size requirements, from the perspective of the calcined, of CaCO3 (calcium carbonate) heating purposes metallurgical activity of lime, is to remove the particles contained in the CO2 (carbon dioxide). Since CO2 separation is buying metallurgy active lime from the surface of the limestone slowly carried towards the inside, then, if the limestone particles are too large metallurgical activity of lime production, the heat transfer process will be very slow decomposition, CO2 separation will require high temperature to produce higher separation pressure. At the same time, also increases the separation time of CO2.
