摘　　要：钢渣添加助磨剂后利用立式行星球磨机对其进行粉磨并进行粒径分析,利用激光粒度分析仪对粉磨后制得的钢渣粉粒径分布D10、D50、D90进行分析。研究分散介质、待测物质量、超声分散时间,搅拌速度,分散剂添加量对检测结果的影响。研究表明,分散介质选用无水乙醇检测结果较为准确,过滤充分的无水乙醇可重复使用;待测物质量控制在0.05~0.1g,超声分散时间控制在30~45min,分散剂添加量在0.2~0.5m L时,检测结果较为准确。搅拌速度对结果数值影响不大。Steel slag after adding grinding aid using vertical planetary ball mill for grinding and particle size analysis,using laser particle size analyzer for grinding the steel slag powder produced after the particle size distribution D10,D50,D90 analysis.Research on the dispersing medium,the mass of the material to be measured,ultrasonic dispersion time,stirring speed,dispersant additive on the test results.The study shows that the results are more accurate when anhydrous ethanol is used as the dispersing medium,and the filtered anhydrous ethanol can be reused;the mass of the material to be tested is controlled at 0.05~0.1g,the ultrasonic dispersion time is controlled at 30~45min,and the amount of dispersant added is at 0.2~0.5mL,and the test results are more accurate.The stirring speed has lttle effect on the result value.
