摘　　要：这是一篇矿物加工工程领域的论文。根据机械力化学原理,采用振动磨的方式对水淬硅锰渣进行粉磨,通过研究粉磨时间对水淬硅锰渣粉比表面积、粒度分布、活性评价等影响,并使用比表面积和激光粒度分析仪、XRD和SEM等表征方法对水淬硅锰渣粉的比表面积、粒径分布、难磨物相和颗粒形貌进行了探讨,同时也研究了不同粉磨时间的水淬硅锰渣粉作掺合料对地聚物抗压强度的影响。结果表明,随着粉磨时间延长,硅锰渣粒度分布逐渐左移,颗粒粒径逐步细化,石英相逐渐向无定形结构转变。从成本角度考虑,当粉磨时间为25 min、比表面积为1.8281 m^(2)/g时作粉煤灰地聚物掺合料时,28 d抗压强度可达26.79 MPa。并确定出难磨物相为直锰辉石晶体结构,以及不同的含锰物相。This is an article in the field of mineral processing engineering.According to the principle of mechanochemistry,the water-quenched silico-manganese slag is ground by vibrating mill.The effect of grinding time on the specific surface area,particle size distribution and activity evaluation of the waterquenched silico-manganese slag is studied,and the specific surface area is used.The specific surface area,particle size distribution,phase analysis and particle morphology of water-quenched silico-manganese slag powder were discussed with laser particle size analyzer,XRD and SEM and other characterization methods.At the same time,the water with different grinding time was also studied.Effect of silicomanganese slag powder as admixture on the compressive strength of geopolymers.The results show that with the extension of the grinding time,the particle size distribution of the silicomanganese slag gradually shifts to the left,the particle size is gradually refined,and the quartz phase gradually changes to an amorphous structure.From the perspective of cost,when the grinding time is 25 min and the specific surface area is 1.8281 m^(2)/g as fly ash geopolymer admixture,the 28 d compressive strength can reach 26.79 MPa.And it is determined that the difficult-to-wear phase is the orthomanganese pyroxene crystal structure,and different manganesecontaining phases.
