• Effects of wet ball-milling on particle dispersion and ...

    1996-2-1  Three different routes were used to fabricate ceramic particle dispersed epoxy composites. Only the wet ball-milling technique was found to be effective for homogeneous dispersion of ceramic particles. Mechanical properties were evaluated for the composites fabricated by three different routes and the results were compared. Good mechanical results ...

    In this study, experimental data for wet- and dry-ground coal samples under wet and dry grinding are characterized by commonly used distribution functions. First, both the R-R and Swrebec functions have superior fitting performances for cumulative particle size curves compared to the other studied functions.

    2020-1-1  Fig. 2 depicts the cumulative particle size curves for the wet and dry grinding under different grinding times. As the grinding time increased from 1 min to 10 min, the dry grinding indicated a faster reduction of the average particle size (d 50) compared to the wet grinding. This is caused by the difference in breakage energy and mill environment between the wet and dry conditions.

    2021-1-22  In terms of mill operation, it was also found that a higher stirrer tip speed and ball filling rate promoted particle size reduction. However, the distribution index k was independent of the ball filling rate, which suggested that the ball filling rate had no obvious effect on the width of the PSD. In addition, for the different stirrer tip speeds, a slight difference in width of the PSD was observed.
