Abstract

The particle size distribution of zircon sand after ball milling at different time was measured and its fractal dimen-sion was calculated,and the fractal characteristics of powder during ball milling were studied by observing the particle mor-phology.The results showed that when the ball milling time was short,ellipsoid sand was broken into irregular shape with sharp edge angle,which reduced the difficulty of further breaking and improved the breaking efficiency,so the fractal dimen-sion increased continuously.However, the formation of a large number of fine particles not only increased the difficulty of further fragmentation,but also hindered the crushing of coarse particles,so the increasing of fractal dimension became slower after ball milling for a longer time.At the same time, the difficulty of fragmentation of the zircon sand with different sizes in ball milling process was different,which led to a rapid increase in the dispersion of particle size distribution with the increas-ing of fractal dimension,which was not conducive to the preparation of powder with grain size distribution.
