how to calculate mill size of a particle

Improving particle size distribution and flow properties

Flow properties of samples showing uneven particle size cannot be compared, as particle size and the resulting specific surface have a large influence on flow properties . Another reason is that particles larger than 3035 μm create a sandy mouthfeel in sensory perception and should therefore be avoided.

The first estimates for the size of the nucleus came from the Rutherford experiment. However, not all nuclei are the same size and to get an accurate measurement, we use a version of the Rutherford experiment with electrons rather than alpha particles. First, let's see how Rutherford deduced the size of the nucleus.
