Smaller particles have more surface area and their bulk density, porosity, flow, and solubility considerably vary from large particles. All these properties will influence the formation, packaging, and processing of dosage forms. Thus, comminution is considered a key step in manufacturing of pharmaceutical products.

Comminution refers to the process of reducing the size of solid materials through mechanical means.

Abstract In granular media, the crushing of individual particles is influenced by the number of contacts with neighbouring particles. This well-known phenomenon of "cushioning" shields the individual particles from crushing when the number of contacts is high. However, in open systems that involve extensive granular flow and bulk motion, like those found in …
