The tool used in the process of sieving is called a sieve or a test sieve.
A sieve is a meshed or perforated device primarily used for separating fine particles from coarse ones.
It operates on the principle of allowing particles smaller than the mesh size to pass through while retaining larger particles.
Sieves come in various sizes and configurations, including single sieves and sieve sets, and can be used in both dry and wet sieving processes.
4 Key Points to Understand Sieves Better
1. Types of Sieves
Single Sieve: This type is used for basic orientation purposes to determine the percentage of undersize and oversize particles.
It involves only one sieve with a defined mesh and a collector pan.
Sieve Set: This involves a stack of several sieves with varying mesh sizes, used together with a collector pan.
The stack is arranged with the largest mesh openings at the top, and the sample is placed on the top sieve.
2. Sieving Processes
Dry Sieving: The most common method where the material is sieved without any liquid.
It can be enhanced using machines like air jet sieving machines, which use air pressure to help in the sieving of fine particles.
Wet Sieving: Used when dealing with materials that are already in suspension or tend to agglomerate.
Water is used to support the sieving process, and the sieving continues until the liquid leaving the sieve stack is clear.
3. Sieve Shakers
Throw-action Sieve Shakers: Also known as vibratory sieve shakers, these devices use an electromagnetic drive to create a three-dimensional movement that distributes the sample uniformly across the sieve.
They are adjustable and can provide precise and reproducible sieving parameters.
Horizontal Sieve Shakers: These move the sieves in horizontal circles and are particularly useful for handling needle-shaped, flat, long, or fibrous samples.
They prevent quick blockage of the sieve mesh and are suitable for large sample sizes.
4. Applications and Importance
Sieves are widely used in various industries for quality control and particle analysis.
Their simplicity, efficiency, and cost-effectiveness make them a fundamental tool in laboratories and industrial processes for profiling particle dimensions.
Despite the availability of more sophisticated instruments, sieves remain crucial due to their reliability and the ability to correlate with historical data.
In conclusion, the sieve is a versatile and essential tool in the process of sieving, offering a practical solution for particle size analysis across diverse applications.
