Method for producing white Portland cement by replacing fluorite raw ore with fluorite powder
The invention discloses white Portland cement produced by replacing fluorite raw ore with fluorite powder, and relates to the technical field of cement production. The method comprises the following steps: S1, raw material pretreatment: selecting high-quality feldspar powder, aluminum slag, limestone raw materials and fluorite powder, and air-drying in a dry place to obtain dry feldspar powder, aluminum slag, limestone raw materials and fluorite powder; s3, grinding treatment is conducted, specifically, the feldspar powder, the aluminum slag, the limestone and the fluorite powder obtained after crushing treatment are mixed according to the proportion of 10%-14%: 1%-4%: 82%-90%: 0.6%-0.9% to be put into a vertical mill to be ground and dried; the fluorite powder is used for replacing fluorite raw ore to produce the white cement raw material, the mixing amount of the fluorite powder is 0.6%-0.9%, half of raw materials can be saved in actual production, the purchase cost of the fluorite powder (waste residues) is 240 yuan/ton lower than that of the raw ore, the production cost of each ton of raw material is reduced by about 7.22 yuan/ton after conversion, the production cost of each ton of clinker raw material is reduced by 12.23 yuan/ton, and the production cost of each ton of clinker raw material is reduced by 12.23 yuan/ton after conversion. And the economic effect is very considerable.
本发明公开了萤石粉代替萤石原矿生产白色硅酸盐水泥，它涉及水泥生产技术领域；它包括以下步骤：S1，原料预处理：挑选优质的长石粉、铝渣、石灰石原料和萤石粉，将其放置在干燥处进行风干，得到干燥的长石粉、铝渣、石灰石原料和萤石粉；S3，磨粉处理：经过破碎处理后的长石粉、铝渣、石灰石和萤石粉按10％‑14％：1％‑4％:82％‑90％:0.6％‑0.9％的比例配料入立磨机中进行研磨及烘干；它用萤石粉代替萤石原矿用于生产白水泥生料，且萤石粉的掺量为0.6％‑0.9％，实际生产中可节约一半的原材料，且萤石粉(废渣)的采购成本要比原矿低240元/吨，折算后的吨生料原料的生产成本下降7.22元/吨左右，吨熟料原料生产成本下降12.23元/吨，带来的经济效果非常可观。
