摘　　要：以河南某地白云母为原料,采用正交试验方法,研究了助磨时间等因素对白云母粒度和比表面积的影响。试验结果表明：助磨时间与搅拌速率对白云母超细磨产品粒度和比表面积的影响最显著。在助磨时间为75 min,搅拌速率为600 r/min,六偏磷酸钠用量为0.02%,4~5 mm、3~4 mm和2~3 mm瓷球磨介比例为3∶5∶2的条件下,可获得-13μm含量为82.60%的超细白云母粉。The influence of the factors, such as grinding time, on the muscovite size and specific area was researched through using muscovite produced by Henan province as the main raw material and the orthogonal experiment. The results showed that the effects of grinding time and agitation speed on the ultra-fine grinding size of muscovite and specific surface area are highly conspicuous. The particle size of 82.6% superfine muscovite obtained was less than 13 μm when the processes were grinding for 75 min, 600 r/min of agitation speed, 0.02% sodium tripolyphosphate in the muscovite, 3∶5∶2 for 4~5 mm, 3~4 mm and 2~3 mm ceramic balls respectively.
