行星式球磨破碎CLRS-1模拟月壤可以获得与月尘粒度分布相似的模拟物质。该方法具有出料物颗粒直径十分细微、损耗率低、操作条件容易控制的特点。本文探讨了CLRS-1模拟月壤研磨后粒度分布受物料比、研磨时间和组分影响。物料比为1∶1∶2时,细化程度最好;随着球磨时间的延长,CLRS-1模拟月壤的中值粒径下降速度减缓,粒径分布范围不断缩小;研磨时间达到6 h,物料达到最细,中值粒径约0.30 μm。由于主要组分火山玻璃、斜长石和橄榄石之间在硬度方面存在明显差异,CLRS-1模拟月壤经研磨后的粒度分布呈现双峰模式。 |

The particle size distribution of lunar dust can be simulated by using planetary ball mill on the CLRS-1 lunar soil simulant. Fine particles of milled product, low attrition rate and easy to control are the advantages of the planetary ball mill. The proportion of grinding balls, CLRS-1 lunar soil simulant and dispersant, grinding time and component are the major factors controlling the particle size distribution of the milled product. In our experiment, we used 50 mL grinding jars, 550 r/min rotation rate, 1 mm grinding balls, and alcohol as dispersant. We find that CLRS-1 is best refined at the proportion of 1∶1∶2, and that the median size of CLRS-1 rate is reduced and the particle distribution is narrow with the grinding time increasing, and that milling CLRS-1 for 6 h can make the finest size particles with a median 0.30 μm. Because of difference in hardness between volcanic glass, plagioclase and olivine, the size distribution of CLRS-1 after milled presents a bimodal pattern. |
