Aug 22 32 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 charg In this process the sample is washed through the Pipette Method Add to the 500 ml measuring cylinder any fine dust which has collected in the base of the sieve set when sieving the sand fraction Fill a deep sink with water and stand the measuring cylinder in it so as to maintain it s temperature as near constant as possible Fill the cylinder with distilled water to the 500 ml mark

The spore extraction was conducted following wet sieving and decanting methods from Gerdemann and Nicolson in 14 and followed by centrifugation techniques from 15 that has been modified How to carry out Wet Sieving Sieve analysis is a simple but proven method of separating bulk materials of all kinds into size fractions and to ascertain the particle size and distribution through weighing the single fractions Usually sieving processes are carried out on dry material However when dry sieving cannot produce an adequate degree

Wet sieving is an ideal sample preparation process for specimens with a high fraction of granular materials and enough fines content present to make sieving difficult The fines can stick together in clumps preventing an accurate assessment by sieving Wet sieving is also useful for direct particle sizing of problem materials including The appropriate sieving method depends on the degree of fineness of the sample material fig 1 Dry sieving is the preferred method for the size range between 40 181 m and 125 mm However the measurement range is limited by properties of the sample such as a tendency to agglomerate density or electrostatic charging Vibratory Sieving
