Sieve testing
Place 3 rubber balls on sieve #30 and 3 rubber balls on sieve #60. Stack all the sieves in order with the lowest number on top. Place the bottom pan under the lowest sieve. Measure out 100–130 grams of grain (about 1 cup) and record the weight. Mill the sample and then place all of it on the top sieve, and add the lid.

The Basic Principles of Sieve Analysis
The sample is placed on the uppermost sieve in the form of a suspension. Rinsing is carried out until the sieving liquid leaving the sieve stack outlet is no longer turbid with solid particles. In wet sieving, the sieving liquid must not alter the physical or chemical properties of the sample. How can an optimal sieve analysis be carried out?

Retsch : Applications : Knowledge Base : Air Jet Sieving
The method used for particle size analysis is primarily determined by the fineness of the material to be sieved. The classic methods of sieving bulk goods with vibratory, horizontal or tap sieve shakers are limited to sizes above 40 microns. When using vibratory sieve shakers for wet sieving, it is possible to push the limit to 20 microns.
