Most sieving processes are carried out on dry materials. However, there are many applications in which wet sieving cannot be avoided, e.g. when the material to be tested is already present as suspension or when a very fine sample that tends to agglomerate has to be sieved. As in dry sieving, a sieve stack is assembled on a sieve shaker.
