Raw material grinding aid for cement clinker firing and preparation method thereof
The invention relates to the field of cement production admixtures, and particularly discloses a raw material grinding aid for cement clinker firing and a preparation method thereof.The raw material grinding aid for cement clinker firing is prepared from, by weight, 10-50 parts of a water reducing agent, 8-30 parts of octadecanamide modified biomass charcoal, 5-25 parts of silicate, 10-40 parts of water and 5-15 parts of humic acid. 2-10 parts of ethylenediamine tetraacetic acid and 4-20 parts of ethylene glycol. The types and mixing amounts of all the raw materials are adjusted, so that after the obtained raw material grinding aid is used for sintering cement clinker, the minimum 80-micron grinding aiding effect and the minimum raw material burnability (f-CaO) are 18.69% and 0.55% respectively; the highest yield per machine hour and the highest compressive strength of clinker in 3d and 28d are 439 t/h, 32.8 MPa and 62.2 MPa respectively, which indicates that the raw material grinding aid has a good grinding aiding effect, can reduce the grinding fineness and burnability of the raw material, and can improve the compressive strength and yield of the clinker.
本申请涉及水泥生产外加剂领域，具体公开了一种用于水泥熟料烧制的生料助磨剂及其制备方法，其中，一种用于水泥熟料烧制的生料助磨剂，包括如下重量份原料：减水剂10‑50份，硬脂酸酰胺改性生物质炭8‑30份，硅酸盐5‑25份，水10‑40份，腐殖酸5‑15份，乙二胺四乙酸2‑10份，乙二醇4‑20份。调节各原料的种类和掺量，使得到的生料助磨剂用于水泥熟料烧结后，80μm助磨效果和生料易烧性（f‑CaO）最低分别为18.69%和0.55%；台时产量、熟料3d和28d抗压强度最高分别为439t/h、32.8MPa和62.2MPa，说明生料助磨剂的助磨效果好，能够降低生料的粉磨细度和易烧性，提高熟料的抗压强度和产量。
