Investigation on Agglomerate Mechanism of Quartz Sand Ultra-fine Comminution

This paper introduces the principle of ball mill manufacture of quartz sand ultra-fine comminution and the characteristic of particle size distribution of powder, analyses the mechanism of particle agglomerate on ball mill manufacture of quartz powder, proposes increasing the dispersant and disperse medium to restrain the agglomerate, and researches the relationship of the dispersant and disperse medium rationally. Based on the ultrasonic technology, the method of ultrasonic disperse is studied and the best time of ultrasonic disperse is determined. This study has important guiding significance for both theory and practice in solving the problem of the particle agglomerate of ultra-fine quartz powder and enhancing the milling efficiency on ball mill manufacture of ultra-fine particle and the precision of ultra-fine quartz powder.
