Then, the bulk aggregate is placed carefully on the top sieve and the material is screened through the various sieves and subsequently become separated by size. Aggregates that couldn't pass through a ⅜" sieve screen, for example, will stay in that sieve while the others pass through until they're caught in the proper sieve.
