Challenges with DPI formulation design. It is well recognized that in DPI formulations, the drug particles in the aerodynamic particle size range of 15 μm have the potential to reach the lower respiratory tract [].However, the fine particles in this size range are extremely cohesive and adhesive, which usually causes poor aerosolization performance.

Fig. 2 shows the timewise evolution of the cumulative PSD experimentally obtained from the laboratory batch ball mill with different single ball sizes (, d B = 20, 30, and 40 mm) using steel balls and alumina balls. As milling progressed and finer particles were generated by breakage, the PSD shifted to the left monotonically even in the fine particle size domain (1100 μm).

Usually, the milling takes place in a grinding chamber, at the bottom of which a nozzle is mounted. The disadvantage is that fluid energy mills have high energy consumption. On the plus side, they provide a very fine powder. Turbo mills/hammer mills; Hammer mills are fairly common. Their crushing chamber houses a shaft with knives mounted on it.

Mineral liberation from ores is an important step in mineral processing. It is necessary to grind the ore to extremely fine size to liberate the mineral from such ores. The planetary ball mill is promising in that it makes grinding to submicron sizes possible by imparting high energy to the ground powder. In this context, there is a need to understand the dynamics of ultrafine grinding within ...
