Flowability refers to the ability of a material, often in powder form, to move and fill a space easily. This property is crucial in various industries, such as pharmaceuticals and food processing, where powders need to be mixed, transported, or packaged efficiently. Good flowability ensures that materials can be handled without clumping or sticking together, which can lead to production issues. Factors affecting flowability include particle size, shape, and moisture content. For instance, fine powders may have poor flowability due to increased surface area and cohesion, while larger, spherical particles typically flow better. Understanding flowability helps in optimizing processes and improving product quality.
