Wet Sieving

Some difficult-to-screen materials can be handled successfully by wet sieving techniques. Apparatuses are available to handle a single sieve or a stack of sieves. Ultrasonic wet sieving devices are also available. Wet sieve analyses are cumbersome to perform and require the sieve fractions to be dried before weighing. Difficult-to-screen materials are usually very fine powders, such as silicon or aluminum, that agglomerate poorly and may not separate completely using many dry sieving techniques.
