摘要： 由于超細礦物材料的應用日益廣泛,粒度分布的測定將是檢驗產(chǎn)品性能的重要技術(shù)手段。本實驗利用粒度分析儀測定超細礦物粉體的粒度分布,通過不同分散介質(zhì)類型、分散時間、分散初始濃度和最大粒徑定值等參數(shù)對粒度測定結(jié)果影響的實驗研究,提出了超細礦物粉體粒度測定的最佳實驗條件。 As the ultra-fine mineral materials are applied more and more extensively,the measurement of the particle size distribution will be an important method to check the product properties.In this test,the method for measurement of the particle size distribution of ultra-fine mineral powder by granulometry is experimentally studied.The effects of dispersant type,dispersing time,concentration of powder sample and maximum size of the powder on the measurement are discussed.And the optimum experimental conditions a...
