The material is passed through sieves of progressively finer mesh and each fraction is weighed.
(a sieve is a net , grid or parallel arrangement of wires/plates that lets particles of dimension finer than the mesh size pass while sorting coarser particles into a dedicated container.
The most simple method is sieving.
Depending on the sizes of the particles, you could use a funnel with filter paper, or perhaps a screen sieve.

winnowing is the separation of solid-solid separated by size and weight whereas sieving is the separation solid-liquid judged by shape and size.
crystallite is the average size of the particle whereas the particle size denotes the individual size of the particle.
When used as a size indicator, "nano" means that the object is so small that its size is best expressed in nanometers.
A sieve analysis test is a procedure to separate fine material from course material by means of a series of woven or perforated surfaces. The proportion of different size particles are recorded. This record is the conclusion of the analysis. Art Gatenby agatenby@cscscientific.com

The mass and size of an alpha particle compare with the masa and size of beta particle in the sense that the alpha particle is significantly larger in both size and mass that the beta and gamma particles. This is why it is called the alpha particle.
Particle size depends on the type of particle.
The most simple method is sieving.
