Witton Cement Group Co., Ltd. to share: a cement clinker formation process, water evaporates: free water with the temperature of the material gradually evaporate cement clinker plant, when the temperature is raised to 100 ~ 150 ℃, the raw meal all free water were excluded. Wet process, the slurry up to 32 ~ 40%, therefore the drying process yield, quality and great influence on heat consumption. 2, clayey material dehydration: When raw material temperature rose to 450 ℃, kaolin off chemically bound water. At 900 ° ~ 950 ℃, the amorphous material into crystalline again, and release heat. 3, carbonate decomposition: calcium and magnesium carbonate are beginning to decompose at 600 ℃, magnesium carbonate at 750 ℃ ??decomposition i.e. vigorously proceeds, and calcium carbonate at about 900 ℃ when rapid decomposition. MgCO3 = MgO + CO2CaCO3 = CaO + CO24, the solid phase reaction: cement clinker minerals can be generated mainly by solid-phase material react with each other when at 800 ~ 1300 ℃. 800 ~ 900 ℃ when, CaO and Al2O3, Fe2O3 reaction of CA, CF; 900 ~ 1100 ℃, the resulting C12A7, C2F, C2S; 1100 ~ 1300 ℃, the resulting C3A, C4AF. Release some heat over the reaction proceeds, the material itself is the temperature rise quickly. 5, tricalcium silicate (C3S) formation and sintering reaction: tricalcium silicate can be a lot to be formed in the liquid phase. When the temperature rises to near 1300 ℃, C3A, C4AF, R2O and other minerals into the liquid cement clinker flux standard, C2S and CaO is dissolved in a high temperature liquid phase, react with each other to generate C3S; C3S formation rate and the firing temperature and reaction time related. Its generation temperature range is generally 1300 ~ 1450 ~ 1300 ℃. After the clinker burning, the temperature began to drop, C3S formation slowed until the liquid solidifies. Witton Cement Group Co., Ltd. Share: cement clinker production steps crushing and pre-homogenization (1) broken cement production process, most of the material to be broken, such as limestone, clay, iron ore and coal. Limestone is the largest amount of raw materials for cement production, cement clinker larger size after mining, high hardness, thus crushing limestone in cement material crushing plays more important role. Crushing grinding process than the process of economic and convenient, reasonable selection of crushing and grinding equipment and the equipment is very important. Before the material into the grinding equipment, as the bulk material crushed to small, uniform particle size, in order to reduce the load on the grinding equipment, increase production 黂 machines. After crushing the material can reduce the separation of materials of different particle size in the transport and storage process, something to obtain raw ingredients evenly, to improve the accuracy of ingredients. (2) pre-homogenization of raw materials technology is pre-homogenization of raw materials in the deposit, whichever is the process of applying scientific stacker reclaimer technology, materials preliminary homogenization, the raw material yard along with storage and homogenization capabilities. Feed pre-homogenization basic principle is that when the material stacked, coming from the stoker to continuously feed a certain manner stacked parallel to each other as much as possible, and the same thickness of the upper and lower overlapping material layer. When dispensing, in the direction perpendicular to the material layer, cut at the same time as all the material layer, in turn cut until the finish to take, or "tile straight to take." Meaning folding Edit this paragraph (a) all of the ingredients in Shanxi cement clinker, reduce quality fluctuations, in order to facilitate higher production quality of clinker burning system and stable production. (2) expand the use of mining resources, improve mining efficiency, maximize coverings and mezzanine mine, no less a waste rock in the process of mining. (3) can be relaxed mining quality and control requirements, lower mining costs mines. (4) on the sticky wet material adaptability. (5) to provide long-term stability of the plant material can also be in the yard of the different components of raw ingredients, making it a pre-dosing yard, create the conditions for stable production and improve equipment operation rate. (6) a high degree of automation. Shan Xi Wei Dayton cement _ Witton cement (certified) _ clinker cement provided by the Wheaton Group, LLC. Witton Cement Group Co., Ltd.
