— Sieving should not be confused with sieving. It is important to understand that sieving is the separation of solids as determined by size and size, and sieving is the separation of solid liquids as determined by shape and size. Sifting is used to separate the heavy and light components of a mixture by wind or blown air.

— Air entrainment or air jet sieving is used when only the portion of sample greater than or less than one sieve is required. It is the recommended sieving technique for fine particulates due to the ability of the air flow to disperse them. PTL has sieves varying from 1,400 µm (14 mesh) down to 20 µm (635 mesh) for this technique. Wet Sieving
