Raw material grinding aid used in cement clinker firing process
The invention is applicable to the technical field of cement production admixtures, and provides a raw material grinding aid used in a cement clinker firing process, the raw material grinding aid is brown liquid and comprises the following components in percentage by mass: 0.1-1% of triterpenoid saponin, 1-10% of aliphatic water reducer, 2-8% of potassium carbonate, 1-3% of sodium carbonate, 2-10% of sodium formate, 20-35% of caprolactam and the balance of water. A certain amount of water is taken to enter a reaction kettle, then stirring is started, heating is conducted till the liquid temperature reaches 70 DEG C, caprolactam is added, hydrolysis ring opening is conducted, sodium formate, sodium carbonate and potassium carbonate are sequentially added, stirring is conducted for 1-1.5 h, triterpenoid saponin and an aliphatic water reducer are added, stirring continues to be conducted for 1 h, the product is obtained, and the product is filtered and guided into a finished product storage tank. After the raw material grinding aid is adopted, the desulfurization efficiency can be up to 98% or above, the desulfurization cost is reduced, the yield of a raw material mill can be increased by 12-25%, the yield in the prior art can only be increased by about 10%, the cement clinker kiln yield can be increased by 10% or above, or standard coal can be saved by 5 kilograms or above, while the yield in the prior art can only be increased by about 5% or coal can be saved by about 3 kilograms.
本发明适用于水泥生产外加剂技术领域，提供一种用于水泥熟料烧制过程中的生料助磨剂，其为褐棕色液体，按质量比例的配方：三萜皂苷0.1‑1％、脂肪族减水剂1‑10％、碳酸钾2‑8％、碳酸钠1‑3％，甲酸钠2‑10％，己内酰胺20‑35％，余量为水；通过先取一定量的水进入反应釜内，随后开始搅拌，加热至液体温度达到70℃，然后加入己内酰胺，水解开环，再依次加入甲酸钠、碳酸钠、碳酸钾，搅拌1‑1.5小时，再加入三萜皂苷、脂肪族减水剂，继续搅拌1小时，即得产品，经过滤，导入成品储罐；采用本发明的生料助磨剂后，可以使脱硫效率高达98％以上，降低了脱硫成本，可以提高生料磨机产量12‑25％，现有技术只能提高10％左右，水泥熟料窑产可以提高10％以上或者节约标准煤5公斤以上，而现有技术只能提高5％左右或者节煤3公斤左右。
