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 1002.5 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.
