Powder is loaded on to the coarsest sieve of the assembled stack and the nest is subjected to mechanical vibration for, say 20 minutes  After this time , the particles are considered to be retained  on the sieve mesh with an aperture corresponding to the minimum or sieve diameter.  A sieving time of 20 minutes is arbitrary and BS 1796 recommends sieving to be continued until less than 0.2% material passes a given sieve aperture in any 5 minutes interval Advantages :  1. This method is very simple.  2. Not expensive 3. Easy to operate  Disadvantages : 1. Not too much precise  method.   2 .  Not applicable for all disperse systems.
