The different types of sieving include:

1. Throw-action sieving: This is a method where the sample is subjected to vigorous motion to ensure effective separation of particles. The motion helps in the relative movement between the sieve and the particles, allowing smaller particles to pass through the mesh while larger ones are retained.

2. Single sieve and sieve set sieving:

   • Single sieve sieving is used to determine the percentage of undersize and oversize particles. It involves using only one sieve with a defined mesh size and is typically used for preliminary assessments or orientation purposes.
   • Sieve set sieving involves using a stack of several sieves with varying mesh sizes. The sieves are arranged with the largest mesh openings at the top. The sample is placed on the top sieve, and as the sieving process occurs, particles are sorted into different sieves based on their size.

3. Dry and wet sieving:

   • Dry sieving is the most common method and is used for dry materials. It involves the use of a sieve stack where the sample is placed on the top sieve, and the sieving process separates the particles based on their size.
   • Wet sieving is used when dealing with materials that are already in suspension or when dealing with fine samples that tend to agglomerate. In this method, a sieve stack is used, and the process is supported by water from a spray nozzle. The sample is placed on the uppermost sieve in the form of a suspension, and the sieving is continued until the liquid leaving the sieve stack is clear.

Each of these sieving methods is chosen based on the specific requirements of the material being tested and the desired level of precision in the particle size analysis. The principles of sieving involve the use of sieve apertures as gauges that either reject or pass particles based on their size, ensuring a thorough and accurate separation of particles.
