During ball milling the weight (grams) ratio of ballstoclay particles was 100: 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 samples in xylene. An

· Ball milling produced particles less than 10 μm after 15 min. Although airjet milling proved capable of particle size reduction of the relatively soft material Pluronic® F68, limitations to the lower size range achievable were observed. The feed rate of the material into the air jet mill was a significant factor and slower feed rates lead to smaller sizes by allowing more time for particle
