The basic sieve analysis consists of weighing an aggregate sample and then passing it through a nest of sieves. The nest of sieves is made up of a stack of wire-cloth screens with progressively smaller openings from top to bottom. The material retained on each sieve (Slideshow 1) is weighed and compared to the total sample mass. ...
