Dimensional measurements
Fragmentation - Theoretical aspects

Any dimensional measurement requires a definition. This is straightforward for particles with simple geometries (such as spheres, cubes, etc.), but problematic for particles with complex shapes, such as non-convex polyhedra or branched particles. These measurements can be used to monitor plant operation or the quality of fragmented products.

A particle has given physical dimensions, and a population of particles is described by their distribution, which has very different meanings depending on whether it is weighted by number, mass or surface area. A narrow distribution is said to be monodisperse; otherwise, it is...
