Particle size reduction is one such method that increases the surface area of the pharmaceutical compounds and subsequently leads to a higher dissolution rate and bioavailability. Conventional processes such as milling, high-pressure homogenization, and spray drying are well established and widely used for particle size reduction.

sized particles. The 30 mm ball diameter milling still performed better than the small ball diameters, but the performance for this ball size had decreased for the -2 mm +1.4 mm mono-size feed compared to the bigger -4 mm +2.8 mm mono-size feed. This therefore shows that should the material feed size continue to decrease, the smaller balls will

The ball milling will break the particle to small size or powder. The main factors that influence the particle size reduction for ball milling is speed and also the time taken. From the results that we get from the experiment, it shows that the higher the speed and the longer the time taken the more the particle reduce the size.

Ball Milling Effect: Morphological Changes. Figure 1 shows effect of milling time on particle size of the Al powder. One observes that BM up to 1 hour increases the particle size. More BM after 1 up to 4 hours sharply decreases the particle size, while further milling after 4 hours does not significantly change it.
