Cohesion

Cohesion refers to the force that holds particles of the same material together, influencing the behavior of powders and bulk solids. This property plays a critical role in industries like pharmaceuticals, food, and chemicals, where material flowability, packing density, and processing efficiency are directly impacted.

On this page, explore the principles of cohesion, its effects on material performance, and strategies to optimize particle behavior for improved industrial applications.
