The resulting particles are between 250-475 μm in size [13]. Supriyono et al. [14, 15] developed a new design of ball milling machine and studied the effect of cycle number and ball diameter on the final particle size and morphology of bamboo charcoal. The final particle sizes are in the range of 250 nm to 500 nm.

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.

With the increase of ball milling time, the particle size of PBG decreased rapidly and then stabilized, and the specific surface area gradually increased and then started to rise back. Ball milling can significantly reduce the standard consistency water requirement of phosphogypsum, resulting in a shorter setting time and higher strength of phosphogypsum.

Ball milling is a size reduction technique that uses media in a rotating cylindrical chamber to mill materials to a fine powder. As the chamber rotates, the media is lifted up on the rising side and then cascades down from near the top of the chamber. With this motion, the particles in between the media and chamber walls are reduced in size by

The size reduction is achieved by a combination of abrasive and impact forces between the particles and the milling media as well as the walls of the mill (Wills, 2006).
