particle size distribution

Particle size distribution describes how many particles of different sizes are present in a sample. It helps us understand whether the material is made up mostly of tiny grains, larger chunks, or a mixture of sizes. This information is important in industries like pharmaceuticals, construction, and agriculture, as it affects how materials behave—like how they flow, settle, or react. The distribution is usually shown as a graph or chart, indicating the range of sizes and their relative amounts. Knowing the particle size distribution ensures the right quality, performance, and processing of materials.
