Three-component Portland cement calcined clinker and preparation method thereof
The invention discloses a three-component Portland cement calcined clinker and a preparation method thereof. According to the invention, 82.6%-86.6% of limestone, 10%-15% of clay and 1.4%-4.4% of iron powder are used as main raw materials, siliceous correction raw material sandstone components are omitted, the calcining mode is adjusted, raw material powder is spread to be thin, thin material fast firing and kiln head coal injection duct short flame sudden firing are conducted, crust of the preheater is prevented from being increased, the kiln tail is prone to ring formation, the kiln skin is thickened, the damage risk of refractory bricks in the kiln is increased, clinker is subjected to sudden burning, the air volume of the grate cooler is increased, meanwhile, the grate cooler also conducts uniform thin material layer operation, the clinker discharged out of the kiln can be rapidly cooled in a full-penetration mode in the shortest time, clinker minerals are prevented from being prone to deformation and pulverization, and the clinker quality is reduced. On one hand, the use amount of sandstone is reduced, mining is reduced, and the natural environment is protected, and on the other hand, compared with traditional four-component formula production, the cost of raw materials per ton is reduced by 10000/ton, the cost of the clinker is reduced by 1.54 million/ton, the production cost is greatly reduced, and the production benefit is improved.
本发明公开了一种三组分硅酸盐水泥煅烧熟料及其制备方法，以石灰石82.6％～86.6％、黏土10％～15％和铁粉1.4％～4.4％三组分为主要原料，取消硅质校正原料砂岩组份，调整煅烧方式，将生料粉末摊薄，进行薄料快烧，窑头喷煤管短焰急烧，防止预热器结皮增多、窑尾易结圈窑皮增厚以及窑内耐火砖受损风险变大，熟料进行急烧，增大了篦冷机风量，同时篦冷机也进行均薄料层操作，能在最短的时间内对出窑熟料进行全渗透的快速冷却，防止熟料矿物易于变型，粉化，降低熟料质量。一方面减少砂岩用量，进而减少矿山开采，保护自然环境，另一方面，较以前传统的四组分配方生产，生料吨成本减少1万/吨，熟料成本减少1.54万/吨，极大降低了生产成本，提高了生产效益。
