| 摘 要： | 以乙二醇与三乙醇胺为原料、无水乙醇为溶剂配制复合助磨剂。将复合助磨剂分别与滚筒渣、脱硫渣和热闷渣进行混合后,利用行星式球磨机进行粉磨。研究钢渣的化学成分与矿物组成、不同助磨剂对钢渣超微粉粒度分布的影响、复合助磨剂对钢渣超微粉的作用机理。结果表明,当乙二醇、三乙醇胺与无水乙醇按体积比2∶2∶2配制复合助磨剂,以钢渣∶复合助磨剂质量体积比为450 g∶6 mL时,钢渣超微粉的粒度分布最佳,即d90为9.14~9.28、d50为3.31~4.20、d10为0.99~1.04和d90-d10为8.11~8.24 μm,其中复合助磨剂对脱硫渣的助磨效果最佳。 |

| Abstract: | Compound grinding aids were prepared with ethylene glycol and triethanolamine as raw material, absolute ethyl alcohol as solvent. The compound grinding aids were minxed with bssf slag, desulfurized slag and hot braised slag respectively, and then grinded by planetary ball mill. The chemical composition and mineral composition of steel slag, the influence of different grinding aids on the particle size distribution of ultrafine steel slag powder, and the action mechanism of composite grinding aids on ultrafine steel slag powder were studied. The results indicated that when ethylene glycol, triethanolamine and absolute ethyl alcohol were used to prepare composite grinding aids according to the volume ratio of 2∶2∶2, and the ratio of steel slag to composite grinding aid was 450 g for 6 mL, the particle size distribution of ultrafine steel slag powder was the best, that is, d90 was 9.14-9.28 μm, d50 was 3.31-4.20 μm, d10 was 0.99-1.04 μm and d90-d10 was 8.11-8.24 μm. And the compound grinding aid had the best grinding effect on desulfurized slag. |
