Lime: limestone particle size. Limestone particle size requirements, from the perspective of the calcined, of CaCO3 (calcium carbonate) the purpose of heating limestone desulfurization price, is contained in the CO2 removal of particulate (carbon dioxide). Since CO2 separation is a quote from the surface of limestone desulfurization limestone slowly carried towards the inside, then, if the particles are too large limestone desulfurization of high quality limestone, the heat transfer process will be very slow decomposition of limestone desulfurization, CO2 of Separation would require too high a temperature to produce higher separation pressure. At the same time, also increases the separation time of CO2. The use of lime is very extensive. Common in many areas of construction, building materials, metallurgy, chemical industry, light industry, environmental protection, medicine and agriculture. Especially in the steel, iron, sintering, copper, aluminum smelting and other industries, the lime as respect slagging agents, solvents or sintered materials, it has played a very important role.
