Micronization is a special grinding technique in which the size of the resulting fragments is in the micrometer range. For larger sizes, we speak instead of pulverization (100 µm) and crushing (50-10 mm).
This process of particle size reduction allows for improved functionality. This type of reduction meets the requirements for the size of the particles of active ingredients and excipients:these parameters are often critical for the formulation of the finished product. The micronization process takes place by placing the material to be processed into a grinding chamber under high pressure. The particles are dragged at high speed by a gaseous fluid (which may be compressed air or nitrogen), and by colliding with each other and with the walls of the chamber, they undergo changes in direction and speed, and as a result, size reduction occurs.
