27.04.2019· For example, reduction to one-half of the original particle size requires about 4-3 kg cm per gm by impact as compared to 18.5 kg-cm by ball mill; that is, the energy requirements are less than 25 percent as much for impact crushing as for ball milling. For great size reduction the application of energy by a single impact becomes less effective so that there would be no advantage in applying

After ball milling for 4 h, the particle size distinctly reduced to approximately 2 μm, with a relatively uniform morphology . As the ball milling was prolonged to 8 h and 10 h, the particle size further reduced to below 1.5 μm, and even particles smaller than 1 μm were observed with good particle dispersion in the sample ( Fig. 2(c) and (d) ).

Ball milling and ultrasonication were used to reduce the particle size and distribution. During ball milling the weight (grams) ratio of balls-to-clay particles was 100:2.5 and the milling operation was run for 24 hours. The effect of different types of balls on particle size reduction and narrowing particle size distribution was studied. The milled particles were dispersed in xylene to disaggregate the clumps. Again, ultrasonication was done on milled
