  • Wet Sieving: A Practical Guide - Gilson Co.

    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:

  • Sieving - Definition Process Sieving Method Of ...

    Sieving is defined as a method in which two or more components of different sizes are separated from a mixture on the basis of the difference in their sizes. Thus, it cannot separate two substances in a mixture which have the same size.
