Sieving - an overview | ScienceDirect Topics

A quantity of the powder is placed on top of the sieve, which is usually vibrated so that the smaller particles fall through the holes in the sieve. Alternative procedures are to lift particles from the sieve by an air jet or in wet sieving to pulse the water. The net effect is the same.

How To Conduct Wet Sieving - Precision Eforming

Aug 29, 2018 · What is wet sieving Wet sieving is a method to separate the coarse material with water or another type of liquid before drying, identifying and analysing. It is a method that can be used to prepare samples, for example, removing the fines, breaking down agglomerates or negate static charges.

Different Sieving Methods for Varying Applications

Aug 11, 2017 · Wet sieving: Wet sieving is a special case of vibratory sieving. The sieving process may be complicated by electrostatic charging, agglomeration, or a high degree of fineness of the sample. In such cases wet sieving may be required. In this process, the sample is washed through the sieve stack in a suitable medium which is generally water.
