The most important approach to obtain APInanoparticles is wet bead milling of aqueous API suspensions containing polymer(s) and/or surfactant(s) for particle stabilization ( avoiding of reagglomeration) (Junghanns, 2008). As the name suggests, wet bead milling requires only water but no organic solvents as media, which is of great advantage.

Introduction. Size reduction of solids involves creating smaller mass units from larger mass units of the same material. To bring this about, the larger mass units need to be subjected to stress by the application of force. Three types of force may be applied, compression, impact and shear.

Abstract. The generation of grinding media wear during wet stirred media milling of organic particles was studied in dependence of product formulation parameters. It was shown that targeted product formulation leads to the reduction of ceramic grinding media wear for a certain product quality. Solids concentration and agglomerate size of ...

It ensures that formulations are consistent from one batch to the next, and it can improve an API's ability to mix with excipients. Milling is one of the most common techniques used to address poor solubility in a new drug compound, not only because it's effective, but also because it's inexpensive compared to other methods.

Dry grinding, as in a jet mill, uses a single pass process; material enters the mill, passes through, and is expelled, reduced in size. In contrast, wet grinding uses a process of recirculation. The slurry is exposed to the grinding media over and over, for hours if necessary, until the desired particle size is achieved.

A mash feed is prepared from a mixture of ingredients, such as grains, protein source, minerals, vitamins and drugs, according to a specified formulation. In most feed mills the mash feed is pelleted in a rolleranddie press (McEllhiney, 1994).
