Sieving
14.19.4.2.1.1 Dry sieving. The coarsest sieve required is placed at the top of the stack in which the square screen openings become progressively smaller down the stack. Sieving generally gives the intermediate measure of a particle because of the way particles orient themselves to pass through the mesh.

Coffee Particle Size Analysis: What Test Sieves Should I Use?
Coffee has the tendency to become oily, especially when freshly ground. For this reason, the standard W.S. Tyler RX-29 Sieve Shaker will deliver the best result in most cases. This is because the 8-inch sieves that are fitted into the RO-TAP are perfect for the fairly coarse particles that are tested during coffee production.
