Particle size

The use of sieves is a common measurement technique, however this process can be more susceptible to human error and is time consuming.

Technology such as dynamic image analysis (DIA) can make particle size distribution analyses much easier.

They still lack the capability of inline measurements for real time monitoring in production environments.

[4][5] This line of research can yield low-cost and real time particle size analysis.

In all methods the size is an indirect measure, obtained by a model that transforms, in abstract way, the real particle shape into a simple and standardized shape, like a sphere (the most usual) or a cuboid (when minimum bounding box is used), where the size parameter (ex.

The particle size of a spherical object can be unambiguously and quantitatively defined by its diameter.
